- Industry / Applications
Fire-X-Trol sprinkler system expansion tanks are designed to accommodate a higher volume of system fluids due to temperature changes, and thereby prevent fire protection systems from being damaged. These expansion tanks are designed for use with water, glycerin, or propylene glycol.
Surge-Trol sprinkler system surge tanks absorb surges from pump start-up and shut-down, with a replaceable bladder that eliminates the expense of replacing tanks.
HOW ARE EXPANSION TANKS USED ?
In a closed loop heating system or cool water HVAC system, expansion tanks limit pressure by absorbing fluid as it expands. By using compressed air, an expansion tank maintains system pressures, accepting and expelling the changing volume of water as it cools and heats. Proper sizing ensures that the system will not exceed critical pressure limits.
