The Advent Balanced Pressure Foam Systems are designed for use with WILLIAMS FIRE & HAZARD CONTROL® (WILLIAMS) THUNDERSTORM®, T-STORM®, and Class A foam concentrates for emergency response to both Class A and Class B fire hazards. With proper calibration, the Advent system may also be used to proportion many other commercially available AFFF, AR-AFFF, and protein foam concentrates.

The Advent system utilizes a positive displacement pump for foam concentrate delivery. The pressure is regulated via the foam concentrate by-pass flow which is returned to the suction side of the pump. A foam-to-water heat exchanger (shell and tube type) keeps the foam cool in the event of a prolonged deadhead pump operation.
