About

  • Fire Protection expansion & surge tanks: ire-X-Trol ASME expansion tanks prevent damage to fire protection systems by accommodating the expanded volume of system fluids that result from temperature changes. This keeps the system pressure below the pressure limitations of the components. Fire-X-Trol can be used with water, glycerin and propylene glycol systems.

Application

Fitted on wet sprinkler systems and particularly on dry and antifreeze systems in unheated spaces, where a sealed pipe network has nowhere to expand when ambient temperature rises. Fire-X-Trol is supplied from 1.5 to 90 gallons and built to ASME Section VIII, Division 1, and works with water, glycerin and propylene glycol. Without a tank the trapped volume lifts pressure until a fitting or a gauge fails, which shows up as an unexplained leak in a system that has never once operated.
