The PistonFire explosion suppressor is a dry chemical suppressor that is designed to meet the new stringent requirements of NFPA 69 (Standard on Explosion Prevention Systems). It is equipped with a supervisory OSHA lockout feature that allows safe entry into protected vessels and prevents arming of the suppression system if a suppressor is locked out. The suppressor is also equipped with a pressure switch that continuously monitors suppressor pressure and alerts operators if the pressure is out of range. The unit discharges an explosion suppressant into a process vessel in milliseconds without the use of explosive actuators, eliminating the need for explosive storage. The suppressor’s five-year actuator service life reduces maintenance costs. Its field-rechargeable design minimizes production downtime in the event of a suppressed explosion and saves on recharge costs.
