Advent Balanced Pressure Foam Systems

Print Page

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. 

Features

  • Multiple foam injection points 
  • Simultaneous variable proportioning rates 
  • Capable of operation with Class A or B foam concentrates 
  • No additional load on the chassis electrical system (less than 1 amp at 12 VDC) 
  • Automatic pressure control 
  • Manual by-pass capability 
  • All mechanical components 
  • Common manifolding not required 
  • Variable foam concentrate flow rates from 12 gpm to 120 gpm (45 Lpm to 454 Lpm) 
  • Broad range of solution flow rates from 40 gpm to 5,000 gpm (151 Lpm to 18,927 Lpm) 

Available Options

  • Tank-to-pump and tank-fill controls
  • A/B tank selector and flush control
  • Pneumatic tank control kit
