Expansion Tanks

Expansion tanks are required in closed loop heating or chilled water HVAC systems to absorb expanding fluid and limit the pressure within a heating or cooling system. A properly sized tank will accommodate the expansion of the system without allowing the system to exceed critical pressure limits. Most of our expansion tank inventory is designed using a pre-pressurized vessel with an internal bladder or diaphragm to manage fluids under pressure. Custom tanks can be created for high pressures and/or special materials for severe duty requirements.
