Explosion Suppression Devices
eSUPPRESSOR™
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 out-tag 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.

PistonFire II
The PistonFire suppression tank consists of a pressurized extinguishing agent storage tank and a valve body with a dust explosion-proof, weather-resistant housing in accordance with the requirements of the National Electrical Manufacture’s Association (“NEMA”). The NEMA-compliant housing houses the actuator mechanism, pressure switch, pressure gauge, fill valve, OSHA control switch, and field wiring connections. With a screwed-on cover and a quick-release connector for easy connection to the field wiring, the NEMA-compliant housing is completely sealed. When an incipient explosion is detected, the suppression container receives a switching signal. The actuating mechanism initiates the rapid release of the pressurized extinguishing agent from dry chemicals into the protected area within milliseconds.
Advantages
- DOT and TC approved – pressurized in the factory, leak tested and transported to the point of use, versus on-site pressurization and leak testing
- Monitored and interlocked low pressure switch according to the latest version of NFPA 69
- Non-explosive initial charges, safe to use (no ATF or UN restrictions)
- OSHA locking plate according to the latest version of NFPA 69
- Nozzles can be tested in the assembled state (NFPA 69), against dismantling or opening of the container by external companies
Product Information
E-HRD Suppressors
The E-HRD suppressor is designed for installation on all types of vessels, ducts and pipes for dusts, gases and hybrid mixtures. The suppressor valve is closed with a domed disc and sealing ring and then pressurized with nitrogen. Beneath the domed disc are the actuation devices, comprising a detonator and line-cutting charge. Within approximately 1.5 milliseconds the line-cutting charge cuts a grooved hole approximately 300 degrees around the domed disc. Once the domed disc is cut, the nitrogen presses the disc down and the entire cross section is made available for the suppressant powder to flow out. Through a special nozzle system, optimal deployment of the suppressant powder is achieved.

PHRD Suppressors
These suppressors are used for explosion suppression of gases, solvent vapours and combustible dusts. The suppressors deliver high rates of suppressant that quench an explosion flame in its early stages, thus preventing a pressure rise from reaching dangerous proportions.
A cylindrical alloy steel container filled with 3kg, 4kg or 16kg of powder suppressant and pressurised to 60 bar (880 psi) with dry nitrogen. Inside the flange is a hinged flap supported by a beam which is kept closed by a latch. Two piston, non-explosive protractor operated actuators are used to initiate opening. When the actuators are activated by means of an electrical impulse from the associated control unit, pistons move the latch, which allows the flap to open. The nitrogen then expels the suppressant at high rate through the spreader assembly into the protected volume.
