Extrol hydronic expansion tanks effectively maintain positive pressure in closed hydronic heating systems. These tanks range in size from 8 to 3963 gallons, and up to 300 PSIG ASME certified.Air separators separate and remove entrained air from fluids by creating a low velocity vortex.Air & dirt separators remove both entrained air and dirt particles from fluids in closed loop, heating and chilled water systems.Buffer tanks add capacity to improve temperature control for chilled or hot water applications, reduce cycling, and provide consistent operation.Compression tanks offer maximum pressures of 125 and 150 PSIG and maximum operating temperatures of 450 degrees Fahrenheit.

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.
