Manufacturing Plant & Laboratories


Manufacturing Plant

We have our own large and modern Workshops: Mechanical workshop, and clean manufacturing Plant for certified electrotechnical products.

They are equipped with brand new machinery for the production of various sets of electrical switchgear, reinforced shell cabinets, explosion proof boxes and other special equipment.

They can be observed in the photo credits that illustrate this section.

Diversity of equipment for specific works, endowed with the best exclusive manufactured tools and advanced electro-mechanical technology in measuring instruments, with quality control of the latest generation and with personal safety controls, of the quantity and range needed for optimum performance and verification of the products, installations and works entrusted to us.

Overpressure test bench for flameproof enclosures

To ensure compliance of the important and demanding European Directive ATEX 94/9/CE of a huge national impact on its implementation, with entry into force on July 1, 2003 to prevent accidents and remove at source possible causes thereof, setting new requirements to comply by facilities, materials, equipment and/or protection systems intended for use in potentially explosive atmospheres, MONTREL Industrial Group, - a pioneer in this field – has established a complete and modern Test Bench for individual tests  of internal overpressure in flameproof enclosures, in accordance with EN 50018: 2000 + A1: 2002 Standard to verify that the equipment is safe in explosive environments.

This Test Bench complements our accreditation as ATEX product manufacturers under Quality Assurance Notification Certificate. It was the first authorized in Spain, having been approved dated September 10, 2003 by the official laboratory J. M. MADARIAGA with Examination Certificate CE Type LOM 03 ATEX 2127X for Equipment or Protection System: electrical switchgear.

It works in automatic operation, with capacity for a simultaneous test of 2 boxes type EJB/EJW with varying pressures accurately measured – through novel instrumentation - from 11.7 bar to 14.4 bar and held for, at minimum, 11s constant for all the boxes.

It is set in an isolated and secure enclosure appropriate to its function within the manufacturing Plant. In general it is also shown in the photo credits we include in the Graphic Information of our installations. It is of note, that within its short validity and practice, has already produced positive results and important services to detect in certain materials supplied by manufacturers of note, concept shortcomings and/or resistance flaws, which thanks to its analysis, will contribute a lot to increase security in the Spanish facilities with explosion proof protection mode (Ex d), as well as  to a greater respect and strict compliance with the ATEX 94/9/CE Standard.

Industrial laboratory for testing and calibration

To carry out electrical and instrumentation precision measurements and also for testing and assays of all our manufactured products, we have a specific Laboratory and sections for Switchgear and/or electotechnical goods, as well as for Instrumentation and Control equipment and components. Both sections are equipped with latest generation instruments and with high precision ranges that enable us the continuous improvement and safe use of our products. Likewise, this Laboratory enable us to provide assurance of proper manufacturing, to issue Certificates and/or Declarations of compliance and to verify control devices.

The Laboratory, can be seen  in its general features and functional layout, from the observation of the photographic credits that we include in the Graphic Information of our facilities.
