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.

The water is contained in an NSF-listed heavy-duty bladder preventing tank corrosion and waterlogging problems. If the bladder extends beyond the normal movement, Wessguard monitor will activate an audible and LED alarm to notify maintenance staff of a potential system issue. In the case of compromised bladder integrity, water level will rise to activate the alarm.
