This Lochinvar Expansion Tank is a crucial component in heating, ventilation, and air conditioning (HVAC) systems. It has a capacity of 2 gallons, which allows it to accommodate the expansion of water as it heats up during the operation of the system. The tank is designed to maintain pressure balance within the HVAC system, preventing potential damage from pressure fluctuations. It features a durable steel shell for long-lasting use and a butyl rubber diaphragm separating the water from the air chamber to prevent water logging issues. The tank operates at a maximum working pressure of 150 pounds per square inch (PSI).
