IEP Technologies Explosion Suppression Systems
Detect and suppress explosions in milliseconds. IEP Technologies Explosion Suppression Systems are designed to detect, within milliseconds, the pressure build-up of an incipient explosion and deliver an explosion extinguishing agent to the enclosed area before destructive pressures develop. The extinguishing agent inhibits the explosion reaction by withdrawing heat from the burning flame and thus lowering its temperature to such an extent that combustion cannot continue. Furthermore, the explosion extinguishing agent forms a barrier between the combustible particles and thus prevents further heat transfer.

EVN 3.0 Explosion relief valve
Many process vessels are located inside a building or areas where standard explosion venting cannot be safely employed. For these applications, the IEP Technologies EVN3.0 flameless explosion vent may be the best protection solution. When an explosion occurs, the EVN3.0 opens and vents the explosion pressure through a flame arrester, thereby cooling the hot gases and quenching the flame. The EVN3.0 integrated opening detection sensor provides an interface with the process control system and allows plant personnel to respond accordingly in case of an explosion within the protected application. The IEP Technologies EVN3.0 flameless vent is self-closing which can reduce “post-event” downtimes. Also available is the EVN3.0H which includes a food grade silicone gasket. Both the EVN3.0 and EVN3.0H are available in a latching model, EVN3.0NC. The EVN3.0NC opens and latches until manually released and can be used in conjuction with isolation flap valves which have been tested to EN16447 – “Alternate testing procedure”.

IEP Technologies Explosion Venting Systems
Relieve Explosion Pressure Safely. An IEP Technologies Explosion Vent is a relief device that ruptures at a predetermined pressure to allow the fireball and explosive pressure to vent to a safe area. Rupture style vents are economical to install and these highly efficient vents fit into the walls of a process volume. They are available in a variety of sizes, configurations and materials to ensure fast reliable operation during an explosion event. IEP Technologies also offers a range of Flameless Vents which are designed to quench the flame front and relieve the pressure. This vent is typically used in applications which cannot be vented to a safe, outside area. Either vent type is typically installed in conjunction with an IEP Technologies Isolation System.
Atexon® automatic spark detection and extinguishing systems by IEP Technologies
Atexon® spark detection and extinguishing systems by IEP Technologies are designed to protect industrial processes by helping reduce the risk of ignition sources such as burning embers from reaching protected equipment. The system detects sparks and extinguishes them automatically without interrupting process operations. The small amount of water extinguishant used, approximately five liters, will greatly limit any interruption to filters or other production machines. Once the ignition source has been mitigated, the system automatically resets to normal operations and is ready to extinguish new ignition sources.
IsoFlap™ Explosion Isolation Flap Valve by IEP Technologies
The IEP Technologies IsoFlap™ Valve is NFPA 654, 69 and EU ATEX Directive compliant, low cost, reliable explosion isolation solution which mitigates explosion propagation risks to upstream equipment. These are effective, self-actuating devices providing inlet explosion isolation to protected vessels handling combustible dusts such as dust collectors, cyclones, and other process equipment.

IVE Flameless Explosion Vent - Bucket Elevator & Process Vessel Protection
The IVE Flameless Explosion Vent provides an explosion protection solution for process vessels, especially bucket elevators, which are located inside a building or areas where standard explosion venting cannot be safely employed. For these applications, flameless explosion vents may be the best protection solution. When an explosion occurs, the venting device opens and vents the explosion pressure and flame through a flame arrester, thereby cooling the hot gases and quenching the flame. The IVE utilizes a stainless steel explosion relief vent and flame arresting mesh enclosed in a durable carbon steel coated frame. The integrated vent burst detection sensor allows plant personnel to respond accordingly in the event of an explosion within the protected application.
SmartDS - Dynamic Explosion Detector System
Dynamic measuring cells in the detector sense changes in pressure. Once pre-programmed pressure values are exceeded, the detector reacts within microseconds to raise an alarm. The MEX Detector has up to two ceramic sensors within a single, solid housing. This is the only detector with algorithmic-based output and decision-making logic based on full-scale explosion tests, expert knowledge and application experience. The output and decision logic provides the highest detection security by evaluating the difference between an explosion pressure rise and process pressure variations. The ceramic cell sensors make the detector more resistant to mechanical damage and corrosive dusts, gases and liquids. By means of a field terminal box (“FAB”) the MEX Detector can be connected to various control units. Competitive advantages of the MEX Detector include: Dynamic pressure detection based on the characteristic temporal profile of pressure increase associated with confined explosion occurrences. This significantly increases false alarm immunity as well as detection security. Utilizes two pressure-sensing cells to increase detection security and redundancy. Field-programmable unit to accommodate a wide range of hazard and process conditions. Also features a history buffer for programming set point during commissioning as well as diagnosis of incident after actuation.
eSUPPRESSOR™ HIGH RATE DISCHARGE SUPPRESSOR
The IEP Technologies eSUPPRESSOR™ is a high-rate discharge suppressor used for explosion suppression and isolation systems. Its electro-mechanical operation is unique to the industry, as no pyrotechnic devices are required for activation. The eSUPPRESSOR has standard features that include pressure monitoring, lock outtag out capability and LED indication of device status. A key benefit is that all the safety functions are fully monitored, which is not possible for any device employing pyrotechnic actuators. The eSUPPRESSOR design and manufacture has SIL2 third party certification. Upon detection of an explosion event, the Explosion Protection Control Unit sends an actuation signal to the eSUPPRESSOR valve mechanism. The highly specified trigger mechanism allows the valve flap to open extremely rapidly (less than 10ms), which allows the suppressant to be discharged through the nozzle system into the protected volume.
Infrared (“IR”) and Ultraviolet Infrared (“UV-IR”) Detectors
Optical detectors include infrared (“IR”) and ultraviolet infrared (“UV-IR”) detectors which are integrated in explosion prevention systems for specific applications. The IR detector is typically used in interconnected duct work for dust-handling systems. The UV-IR detector is used in combustible gas or vapor protection systems such as aerosol fill rooms and chemical storage rooms.
High Speed Isolation Valve
The High-Speed Isolation Valve provides a solution for vital explosion isolation applications. It operates in milliseconds to provide a mechanical barrier within a pipeline. The High-Speed Isolation Valve has a stainless-steel body incorporating a fully ported stainless-steel valve gate. The valve is designed to withstand a 150 Psi pressure wave from a deflagration without deformation. Closure is achieved in milliseconds by rapidly discharging nitrogen into a piston actuator. The nitrogen is supplied by an IEP Technologies High-Rate Discharge Bottle. Detection is typically provided by an IEP Technologies explosion pressure detector. The detector is monitored by an IEP Technologies control unit which provides supervision, alarm, system actuation, and process shutdown. Typical applications for the valve include explosion isolation on dust collectors, mills, fans, vapor recovery lines, dryers, and other interconnected process equipment.
