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.
