Wessels has developed an excellent reputation for high quality products for hot or chilled water HVAC systems. Mason-Dallas is proud to offer Wessels Tanks.
Smart Thermal Expansion Tanks Wessels Type TXA-WG Smart Tanks are ASME removable bladder type pre-charged thermal expansion tanks with WessGuard® bladder monitor. TXA’s are designed to be installed between a backflow preventor and a hot water heater to accept the expanded volume of hot water keeping the system pressures below relief valve settings.
Compression Expansion Tanks. Compression tanks are designed to absorb expansion forces and control the pressure in heating/cooling systems. This tank is the oldest style design and works well when the air is controlled and kept in the tank, not in the system.
Diaphragm Expansion Tanks. The diaphragm tank has been developed to allow the systems air cushion to be separated from the systems water. No waterlogging of the tank can occur as the air is held between the tank wall and the outside of a bladder placed inside the tank, while the system water is contained inside the bladder. This changes the system to an air elimination system, as any air extracted from the system water is passed out of the system into the atmosphere.
Smart Expansion Tanks. Wessels Type NLA-WG Smart Tanks are ASME removable bladder type pre-charged expansion tanks with WessGuard® bladder monitor. They are designed to absorb the expansion forces and control the pressure in heating/cooling systems.
Shock & Surge Tanks. Wessels Type SSA Tanks are ASME replaceable bladder type pre-charge hydropneumatic tanks for commercial and industrial, municipal, and well water systems, to effectively control water hammer shock, and pump start-up/shut-down water surge.
