Access control, the first security measure

We are specialists in the manufacture of access control cabinets that are characterized by their finish and high precision. Our products adapt to any type of company, purpose and size. The purpose of access control systems is none other than to grant permission for authorized persons to enter a building, office or warehouse.

Virtually all companies need to control the people accessing the inside of their facilities. In this sense, technology has made it possible to create electronic access systems. Physical security is often one of the main reasons for the need to install such controls. Most companies or organizations use different levels of access control depending on security levels, from access to property to that involving entry into specific areas. Devices including mechanical, electrical or biometric systems are installed for this purpose.

In general, we can say that access control devices will be installed at all entrances and exits. An important aspect is the durability of these controls. In this sense, at Delinte we are not only capable of manufacturing any prototype that is proposed to us, but we always use the best materials.

We manufacture the structures of the access control cabinets in galvanized steel or stainless steel. We rely on the fact that these materials offer the necessary resistance to atmospheric agents and also to possible acts of vandalism. In any case, we ensure that all our access control cabinets use materials that have passed the most rigorous tests for resistance to water, dust and, especially, the corrosive maritime environment.

But among our functions is also the realization of other types of equipment such as auxiliary equipment for tunnels, toll parking, road signs, etc.

Control of the number of people, essential

Controlling the number of people entering a certain space, be it a parking lot or a public show, has always been very important, but today with the pandemic it has become essential. In this sense, control systems that use the emission of ticktes are among the most widely used. Our cabinets are specifically designed to house both the hardware and software required to perform these functions.

In this regard, it is very important to be able to guarantee the continuous operation of the machines for as long as possible, regardless of the weather and the atmospheric factors they have to face.

At Mecanizados Delinte we have been specializing for more than 30 years in providing our customers with the best possible solutions. We sit down with them to get to know their ideas and needs in order to develop the prototypes they need. Designs that our professionals then manufacture with care, taking care of all the details, from the quality of the materials to all the processes inherent to the work.

At Delinte we strive to ensure that both the service provided and the product manufactured meet our customers’ expectations. To this end, we continually strive to maintain and update our technical resources. And in the appropriate selection of our suppliers by means of objective criteria for the evaluation of their products and/or services.

A fundamental characteristic that they must have is their resistance. The shelter type cabins are made to measure, according to the needs indicated by our customers. It is important that they adapt to the climatic conditions of the area where they will be located. But they must also be able to withstand transportation and be able to house the equipment that needs to be installed in them.

In stainless or galvanized steel, higher resistance

Other variables that must be taken into account are that they have the capacity to dissipate the heat of the equipment, that they comply with the technical requirements and that they have safety and control systems, in addition to allowing energy supply.

As we can see, there are many conditions and variables to take into account for their design and manufacture. Adapting to the required standards and customer needs is very important. Shelter cabins range in size from 2000x1500x2500 (WxDxH) mm to 14000x2800x2700 (WxDxH) mm.

In terms of materials, we focus on strength. That is why we use galvanized steel or stainless steel. The cabins are insulated with rock wool and internally lined with stainless steel, galvanized steel and then painted or plasticized chipboard. Galvanized steel is characterized by a zinc coating that makes it more resistant to rust, since it protects it from the action of water and humidity.

In addition, zinc is a metal that is highly resistant to scratches and provides a satin appearance that makes steel more aesthetically pleasing. Depending on different factors, a piece of industrial galvanized steel with a zinc layer thickness of only one millimeter can last up to 70 years without maintenance. In addition, it is an inexpensive material that can be recycled several times.

Rock wool is a material made of volcanic rock. It is one of the most widely used as thermal insulation and fire protection in buildings. It is a material that was discovered at the beginning of the 20th century and, shortly thereafter, it was manufactured artificially.

Individually designed cabins

In order to meet the demands of our customers, the cabins are individually designed according to the characteristics and plans they request. Subsequently, they are manufactured by studying their use, their final location and the required durability. The cabinets can withstand extreme environments in terms of temperature, humidity, tightness, cooling or vandalism, since the instruments they contain are generally of great value.

Numerous companies such as Repsol, BP, Cepsa, Exxon Mobile, Lukoil, Tecnicas Reunidas, PEMEX, have valued satisfactorily the quality and finish of our cabins for more than 30 years, making us a benchmark in the sector.

Shelter cabins allow for easy and effective installation and handling of electrical power systems, which will be protected in a pressurized and thermally controlled enclosure rather than exposed to the elements.

There are more than 600 fixed measuring stations throughout the country, in addition to several analyzers. The Ministry for Ecological Transition (MITECO), through the State Meteorological Agency, the EMEP/VAG/CAMP network, is also responsible for collecting data to obtain information on transboundary pollution and to comply with Spain’s obligations under the Geneva Convention on Long-Range Transboundary Air Pollution.

Located in representative spaces

The emission measurement booths are responsible for measuring the concentrations of tropospheric ozone and other atmospheric pollutants such as sulfur dioxide (SO2), nitrogen oxide (NOx), carbon monoxide (CO), hydrocarbons (BTX) and heavy metal particles that may remain suspended in the air. The purpose of these facilities, in addition to adequate control, is to be able to warn the population so that they can take protective measures.

Emission measurement booths can be fixed or mobile. The latter are usually used for temporary campaigns or research work. They can also serve as auxiliary cabins when there is a failure in one of the fixed cabins.

One of the first issues to be taken into account is the geographic space in which they are to be placed. It should respond to an environment that is representative of the area. In addition, they have to be equipped in such a way that their design requires certain aspects to be taken into account.

Characteristics of emission measurement cabinets

The internal temperature of the station should be maintained between 18 and 20 degrees. This implies the need for an air conditioning system. If toxic gases are handled, the cabins must also be equipped with fans or extractors. Analyzers, calibrator, communication equipment etc. should be placed on shelves or cabinets.

Sampling equipment should be fixed to the wall with metal fittings. The cab must also have space for a shelf or desk for the operator to work at. If explosive gases are to be handled, the corresponding safety measures must be taken. In any case, you must always have a fire extinguisher.

Measuring booths can be made of different materials. We focus on their manufacture in galvanized steel or stainless steel for their high resistance. Galvanized steel is steel that undergoes a hot-dip process with molten zinc. This generates a zinc layer on the surface that prevents oxidation. In addition, they are insulated with rock wool and internally lined with stainless steel, galvanized steel and then painted or plasticized chipboard. In terms of space, we manufacture shelter cabins from 2000x1500x2500 (WxDxH) mm to 14000x2800x2700 (WxDxH) mm. Always adapted to the type of equipment they must contain.

For more than 30 years, numerous institutions and private companies have chosen to rely on us for the use of shelter cabins.

There are different types of heat treatments depending on the objective to be achieved and the reactions that are achieved are obviously also different. This type of treatment hardens or softens a product, modifies its structure or changes some of its characteristics so that the final result meets our needs.

The different heat treatments include carburizing, nitriding, tempering, carbonitriding, annealing, normalizing, isothermal annealing and quenching.

Tempering, the main treatment in the industry

Tempering is one of the most widely used heat treatments in the machining field. Basically, it consists of heating a material, usually steel, above its transformation point. We are talking about temperatures that may well exceed 800 or 900 degrees Celsius, and cool it quickly in water or oil. The purpose of this whole process is to obtain a much more resistant piece, in which its degree of fragility is reduced.

The tempering process seeks to achieve a balance between hardness and strength in the product.

Although it may seem strange, the use of tempered steel has been used for centuries. Already in feudal Japan, blacksmiths were in charge of making katanas, swords and other weapons with this material. To do this they smeared clay on specific parts of a steel blade and heated it in a forge, then cooled the blade in water.

Obviously today’s work processes have evolved, but at the core, the objective and principles remain the same.

Of course, steel is not the only metal that can be tempered, but it is one of the metals that offers the most possibilities, since by doing so, very attractive qualities can be achieved. For example, it is made to have a higher degree of hardness, to be less fragile, to withstand greater forces, to relieve stresses, etc.

How and why steel is hardened

To harden it, the steel must be heated to a temperature that exceeds its transformation point, which is called the quenching temperature. In this way it is possible to vary its structure, obtaining a crystalline structure that is ideal for rapid cooling of the piece. The cooling must be carried out in a certain way that will vary according to the composition of the steel in order to obtain the desired equilibrium.

To obtain different types of hardening , other elements such as carbon, nitrogen, cyanides or other compounds can be added.

The process of heating steel is called austenitization. What is achieved by heating it is to accommodate much more carbon in its structure, forming austenite, which is nothing more than a certain arrangement of iron and carbon atoms. Upon rapid cooling, martensite is formed, i.e., a crystal that gives the steel its maximum possible strength.

A complete part, including its core, can be hardened. Or only its external surface can be hardened, giving the core a different degree of hardness and flexibility.

In short, steel tempering provides this material with the properties we need to be able to manufacture parts that are resistant and suitable for the work for which they are intended, such as swas frames.

We install control cabinets all over the world.

At Delinte, we have been manufacturing traffic regulators for SpainThe company’s products are also used in Europe, the Middle East and Latin America. As a base material we use galvanized steel or stainless steel that offer adequate resistance to atmospheric agents and also to possible acts of vandalism. In any case, we ensure that all our access control cabinets are made of materials that have passed the most rigorous tests for resistance to water, dust and especially the corrosive maritime environment.

At Delinte we always add top quality raw materials to the experience and to the experience and know-how of our team, so that our control cabinets stand the test of time very well.

In addition, we also manufacture auxiliary equipment for tunnels, toll parking, road signaling, etc.

Tailored to the needs of our customers

Obviously the function of the control cabinets is to protect the equipment containing the protect the equipment they contain. Electronically controlled access provides users with great flexibility. All the compartments of our cabinets are specially designed to house and protect the different electronic systems, but they can also be adapted according to the needs and requirements of our customers.

The cabinets for the control of gauging control are becoming very important in the times we live in. The pandemic caused by Covid-19 means that access to different locations and venues must be more tightly controlled. Having automatic control mechanisms is a great advantage.

The access control systems can be located in communities of neighbors, in garages, in companies or in other types of spaces that need to manage who enters and who does not. These control systems are designed to function in such a way that the technology they house can provide sophisticated security solutions. Our access control cabinets have to be effective for to allow the installation of control software, which ultimatelyThe software is ultimately responsible for allowing or disallowing people to enter the protected areas.

The access control system must allow the identification of the user. user identification through different types of methods. These can be personal cards, secret codes, biometric recognition, etc. But they can also provide other types of solutions such as time control, capacity control, localization, etcetera.

In each of the accesses or doors, one of our access cabinets will be installed in which the readers will be placed, which are the ones that check if the userss have access permits to the protected zone or area. These accesses can be by proximity, for example, using identification cards, by radio frequency through a remote control, or even by Bluetooth, which allows cell phones to be configured as identification devices. A more sophisticated solution, which is also used, is the biometric fingerprint.

On the other hand, access control systems can be stand-alone, i.e. there is only one basic control that gives access to the door. Or they can be centralized, whereby several readers are placed and have to communicate with each other.

What are the shelter cabins like?

Shelter is an English word that could be translated into Spanish as “refugio”. Shelter would be a structure that has the function of protecting from the weather. The term is also used in the sense of container, since it is responsible for housing and protecting the equipment that is collected inside it.

The usefulness of shelter cabins extends to virtually all areas of production. Depending on the use to which they are going to be put, the cabins will have a series of needs that we adapt at the time of manufacturing. In terms of sizes we move in dimensions ranging from 2000x1500x2500 (WxDxH) mm to 14000x2800x2700 (WxDxH) mm.

An example of how are the cabins that we manufacture in Delinte can be found in air quality measurement cabins, which are distributed throughout the Spanish geography and also in many points outside our country. This type of cabinets must house all the equipment to measure both chemical pollutants and meteorological parameters. Air pollution has become one of the main concerns in our cities, which is why it is important to have adequate control systems in place. In this sense, our cabins house the equipment that automatically collects the basic information for atmospheric monitoring.

Materials to create the shelter cabins

In order to fulfill their function, shelter cabins must be sufficiently resistant and robust to be able to withstand both weather conditions and possible acts of vandalism. In this sense, at Delinte we work with the best high quality materials from European Union countries. We also use thermal insulators from leading manufacturers that guarantee the required specifications. We have our own manufacturing and assembly method that favors a robust construction.

Depending on the case, we use galvanized steel or stainless steel for their construction. Galvanized steel is steel that undergoes a hot-dip process with molten zinc. This generates a zinc layer on the surface that prevents oxidation. Stainless steel, on the other hand, has a manufacturing process by which, through a series of transformations, the raw materials are melted until the desired thickness and diameter of the parts are obtained. It is a corrosion-resistant material by a unique process that, in a simplified form, causes chromium oxide molecules to immediately restore any scratches to the metal.

Our cabins are insulated with rock wool. It is a mineral-type insulation that uses two raw materials: basaltic rocks, which are of volcanic origin, and coke ore, which comes from coal. The main advantage of this material is its fireproof character. In addition, it is an excellent acoustic and thermal insulator.

The shelter cabins have a painted finish and are always adapted to the environmental and seismic conditions of the areas where they are to be installed. Of course, its construction and dimensions are adjusted to the needs expressed by the customer, depending on the equipment that needs to be housed inside. In addition, this type of cabins can be easily moved.

The regulation affects ATEX enclosures individually, but not only. The detailed guidelines result in the evaluation of all components as well. This is because of the seriousness of an explosion in the workplace. For this reason, special care is taken to ensure that they do not come into contact with particularly susceptible substances or materials.

Possibility of explosion

Explosive atmospheres are defined as those in which there is a mixture of flammable substances in the form of gases, vapors or dusts in the air. Under these conditions, when ignition of these substances occurs, the total propagation of combustion is triggered. They are present in a large number of industries, from agriculture and livestock to timber and chemicals, to give just a few examples.

For an explosion to occur, several conditions must be met simultaneously, such as the mixture of combustible substances with the oxygen present in the air in the precise proportion that creates an explosive atmosphere and that this is in contact with a source of ignition.

It is clear that in this type of atmosphere it is very important that arcing and sparks that may occur due to failures or perhaps misuse of the instrumentation be avoided. separated as far as possible from explosive atmospheresor minimize their contact to the point of avoiding ignition.

Protection in ATEX atmospheres

Directive 2014/34/EU (ATEX 95), which came into force on April 20, 2016, defines the specifications for the equipment and use of electrical and non-electrical equipment in an explosive atmosphere. A classification scheme sets out the essential requirements on safety and health protection for equipment.

All equipment installed in an ATEX zone must be protected against the risk of explosion. The equipment in these zones, such as the ATEX cabinet, must be certified by an organization approved for this purpose in accordance with the aforementioned directive. The certification consists of a specific marking of the product category and the area and atmosphere in which it can be used.

ATEX cabinets are certified as components. They are combined with other ATEX components (electrical, pneumatic, hydraulic, etc.) to form a final solution that must be ATEX certified.

All the ATEX cabinets that we manufacture at
Mecanizados Delinte
comply with the required standards of protection against the risk of explosion. We manufacture cabinets in galvanized sheet metal or stainless steel for the analysis of liquids or gases in ATEX zones. These products can be SAM enclosures, ATEX or pressurized enclosures. They can be heated or insulated with rock wool and meet IP or NEMA standards.

Our company has the technical capacity to create prototypes and industrial metal developments to achieve unique parts for any industrial sector, especially electrical metal cabinets.

What is GRP and what is it used for?

GRP(Glass Reinforced Plastic) is a composite material, consisting of a plastic or resin matrix reinforced with glass fibers. It is a light, rigid and resistant material that offers a good response to corrosion and wear. It is also useful as an insulator, either acoustic or electrical. The truth is that its properties vary depending on the amount of fiber it contains.

Among other uses, it is used in the automotive and aeronautical industries, as well as in structural elements of construction and in water tanks.

The use of steel

Steel is an alloy of iron and carbon. The latter preserves the metallic characteristics of iron but improves its physical and chemical properties. To be considered steel, the alloy of iron and carbon must be less than 1.7%. It is a hard yet elastic material that is malleable to create different types of products.

Steel as a material has very good mechanical properties as it is very strong and also inexpensive. On the other hand, it is also possible to alloy steel with other materials such as chromium, magnesium, tungsten, zinc, etc. to improve its properties.

Stainless steel is an excellent material for its resistance to corrosion and oxidation, mainly due to the presence of chromium, which allows the formation of a thin film that is impermeable and resistant to corrosives. In addition, stainless steel is easy to clean, which makes it hygienic. It has a very low maintenance cost, resists well to both high temperatures and temperature variation and is a recyclable material, thus contributing to the care of the planet.

At Delinte we manufacture the products you need

In Delinte we have manufactured since our beginnings in the 80’s, in addition to access control or metallic cabinets, all kinds of metallic steel constructions. Our philosophy is that, after all, almost anything can be created. Our products include protective fences for sidewalks that are highly resistant to corrosion caused by inclement weather, advertising billboards, metal walkways and enclosures for different uses. If you have an idea or need a specific product that you want to be made of steel, Delinte will make it happen.

We could say that the first electric train was the one designed by Werner Von Siemens in 1879 in Berlin. In Spain, the first electrified line is considered to be the Gergal- Santa Fe (Almería) section, which was inaugurated in 1911.

Electrical circuit of the trains

The electrical circuit is responsible for supplying power to the trains. It consists of a series of installations that are in charge of adapting the electricity and the correct operation of the motors, in addition to ensuring that electricity reaches the train from the installations along its entire length.

Trains demand a high power of electricity, we are talking about voltages ranging from 1500 to 3000 Vdc. Originally, the trains had their own power plants, but this was expensive and impractical once power plants began to operate close to urban centers. Even so, it is necessary to convert the high voltage energy with the one that needs to be injected to the catenary, for this purpose there are the substations.

There are two ways for trains to capture electricity, through an electrified third rail, a system used in Germany and other parts of the world. Or through an overhead contact line, called catenary, the system used in Spain. The train or tramway accesses electricity through the friction of the trolley or pantograph located in the power car. Catenaries can be powered with both direct and alternating current.

Train motors are in charge of converting electrical energy into mechanical traction, which is, after all, what produces the movement of the railroad. The motors and the equipment that make their operation possible are installed in the power car.

Finally, the return circuit is the one that facilitates the return of the energy used by the motors back to the substation.

Safety systems

Of course, the circuit is equipped with a series of safety systems that cut off the electricity supply if any anomaly is detected. The main safety systems are located in the substations, which automatically check for problems up to three times. If confirmed, power is suspended until the maintenance team fixes the error.

Extra-fast circuit breakers are the safety system installed on the train itself. In this case, it is up to the driver to reset them if they jump. Of course, lightning conductors are installed along the substations and the catenary.

At Delinte we are specialists in the installation of metallic electrical cabinets and racks for train control. They are installed inside and comply with the UNE-15085-CL2 standard in which Delinte is certified for aluminum, stainless steel and carbon steel constructions. To contact us simply call 916 77 03 64 or fill out the form on our website and we will contact you to inform you and provide you with a quote according to your needs.
