Passive Protection & Isolation

Production requirements have caused Process Engineers to find Protection Methods that limit the down time associated with Explosion Protection.  Up to recently Protection Systems used Active Detection and/or Monitoring Systems to ensure the functionality of the Protection System.  This caused process interruptions on a scheduled and unscheduled basis for system maintenance.  With the New ATEX Explosion Valve and Standard Venting Methods the need for these process stoppages can be reduced with the unscheduled ones virtually eliminated.  The systems can use Standard Frangible Vents, Flameless Vents or Explosion Doors based on the needs of the Process and Operation Procedures....Read more

Active Protection & Isolation


Active Protection Options

Explosion Suppression Systems provide an alternate to Passive Venting Systems.  The systems cool the advancing deflagration before destructive pressures can be reached.  These systems provide alternatives for the protection of various size and types of systems.  See information below for individual system benefits...  read more

Active Isolation Methods

To prevent the propagation of a deflagration to other process components reducing the chance of a secondary event active mechanical and chemical methods are used.  The active mechanical methods include mechanical Quick Sliding Valves of Various Designs.  Mechanical valves provide flame and pressure isolation. The active chemical methods use standard suppression system containers for the flame isolation and pressure mitigation of the event. read more

Prevention & Early Detection


In the past all CO systems were developed to compensate for environmental CO changes. Nowadays it proves that this is not working for a wide range of more

The Largest Test Vessel in the World



ATEX has completed the installation of its new test vessel.  The new vessel, we believe, is the largest in the world at 140 cubic meters.  In the past the test vessels were designed around spherical shapes with center firing...Continue Reading


CO Early Detection

ATEX CO Systems can detect the incipient development of a fire by sensing and comparing the inlet and outlet air for CO content. The System monitors the process air for the presence of volatile pyrolysis components, immediately registering these indications of thermal decomposition or of smoulder spot development. The system detects a difference of 1 ppm. Self-ignition processes are detected as soon as they start in this way, and can be stopped effectively. Drying milk in spray towers is one important application.The probes are placed at all air inlets and outlets, continually sending air samples to the CO detection control cabinet where they are treated and filtered. The differential between the sum of inlet samples is compared with the sum of outlet samples. When the CO differential reaches one of three programmable levels, the appropriate alarm is signaled...Read more

Quick Sliding Valve

The ATEX Quick Sliding Valve uses Gas Generators to close the valve if a deflagration is detected as provided with most new systems. But additionally ATEX valves are provided with plant air operated slow stroke functions to allow the manual opening and closing of the valve for maintenance. This ATEX feature provided the operator with an easy check of the valve mechanics since the slow stroke test is more severe than the anger test. This test meets the requirements of NFAP without an anger test that destroys the firing mechanism defeating the purpose of the test. The valve is connected by a removable plug to allow maintenance as required and easy valve disconnection as required without disconnecting wiring. Because of the unique ATEX benefits the entire system can be user maintainable without the high cost of factory service... Read more
