Series PLT potable water expansion tanks are designed to absorb the increased volume of water created by thermal expansion and to maintain balanced pressure throughout the potable water supply system. Series PLT tanks feature a pre-pressurized steel tank with an expansion membrane that prevents contact of the water with the air in the tank. This prevents loss of air to the water and ensures long and trouble-free life for the system. These tanks may be used with all types of Direct Fired Hot Water Heaters (gas, oil or electric) and hot water storage tanks.

• Heated water expands, and in a domestic hot water system, the system may be closed when the potable water system is isolated from the public water supply by a one-way valve such as pressure reducing valve, backflow preventer or check valve
• Rugged flexible butyl diaphragm
• Field adjustable pre-charge
• Can be used with most standard hot water heaters and storage tanks
• It shall have a Butyl diaphragm separating the air chamber from the water containing chamber
• Stainless steel inlet connection
• The potable water expansion tank shall be of drawn steel construction
• Materials of manufacture for the diaphragm shall be FDA approved
