Expansion Tanks
Expansion tanks keep fluid circulating and maintain minimum pressure. They’re required in a close loop heating or chilled water HVAC system and absorb expanding fluid and limit pressure. The compressed air maintains system pressure to keep the system from exceeding pressure limits. Most possess diaphragms to separate air from system water.
