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.
Types & Variants
| Type | Description |
|---|---|
| Diaphragm Expansion Tank (Vertical) | Fixed-diaphragm tanks for closed chilled-water and condenser-water loops, typical pre-charge 1.5–2.0 bar. |
| Bladder Expansion Tank (Replaceable) | Replaceable-bladder tanks for larger central-plant duty — bladder field-replaceable without removing the vessel. |
| Domestic Hot-Water Expansion | Small expansion tanks for storage-tank water heaters and solar hot-water systems — potable-water-rated. |
