Technical Data | Related Products

Manufactured by: Wessels
Model: NVA Series

Wessels NVA Tanks are ASME removable bladder type pre-charged expansion tanks. They are designed to absorb the expansion forces and control the pressure in heating/cooling systems. The system’s expanded water (fully compatible with water/glycol mixtures) is contained in a full acceptance heavy-duty butyl bladder that prevents tank corrosion and waterlogging problems. All NVA expansion tanks can be installed vertically or horizontally.
