Expansion
Tanks

Closed-loop diaphragm expansion vessels for HVAC chilled-water and hot-water systems, condenser-water loops, and solar / domestic hot-water installations.

Expansion Tanks for Closed-Loop Systems

Water expands when heated and contracts when cooled — closed-loop HVAC and hot-water systems need an expansion tank to absorb that volume change without spiking pressure into relief valves. SMPC supplies pre-charged diaphragm expansion tanks rated for chilled-water and hot-water service, sized from 12 L residential to 1500 L commercial central plant.
