• SIRON Fire Protection Valves

Expansion Tanks & Surge-Trol Tanks

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. Expansion tanks can be used with water, glycerin and propylene glycol systems.

Surge-Trol ASME tanks are designed to absorb pump start-up and shut-down surges in fire protection sprinkler systems. Available in sizes from 10 to 528 gallons, Surge-Trol’s replaceable, heavy duty bladder avoids costly tank replacement. Tanks 53 gallons and larger are UL listed. All models are FM approved.
