Expansion Tanks



Expansion Tank

Patterson Type NLA 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
heavy-duty bladder preventing tank corrosion and
waterlogging problems. NLA expansion tanks
reduce tank sizes up to 80%.
