THERMAL EXPANSION TANKS

THERMAL EXPANSION TANKS TXA-FF Full Flow (Flow-Through) – ASME 14 3 Wessels type TXA-FF tanks are ASME removable bladder type pre-charged tanks designed as a multifunctional bladder for controlling system pressures in Thermal Expansion, Hydronic Expansion, and Hydro-Pneumatic applications. The TXA-FF design incorporates a unique flow-through design that promotes fluid mixing. Mixing of the fluid inside the bladder tank disrupts stagnant water, preventing growth of potentially harmful bacteria colonies. The water is contained in a heavy-duty butyl bladder, preventing tank corrosion and waterlogging. REMOVABLE BLADDER TANK – 150 PSI ASME Syst. Wt. Model Part No. Gal. Accept. Dia. Ht. Conn. (Lbs.)

THERMAL EXPANSION TANKS WESSGUARD ® RETROFIT FOR TXA The bladder-style thermal expansion tank function is to accept expanded water created during the heating process that occurs in a domestic water heating system. The properly sized thermal expansion tank will control pressure increases in the water heating system based on the captured compressible air chamber within the tank to the designer’s acceptable limits. Factors that can affect the pressures in the water heating system: Properly sized thermal expansion tank Properly installed and pre-charge adjusted thermal expansion tank Fluctuations in line pressure Water heater temperature range fluctuations 14 3 Until now the diagnosis of the critical component interaction arises only after expensive damages have been caused by this excessive pressure. WessGuard ® was developed to monitor the fluid within the thermal expansion tank by determining excessive movement of the vessel bladder. WessGuard ® incorporates a capacitive proximity sensor that determines if fluid levels in the thermal expansion tank exceed “normal” operating conditions. Furthermore, if a thermal expansion tank bladder is compromised, WessGuard ® monitors the rising fluid level in the tank. WessGuard ® is designed to monitor these tank conditions and alert the installer or maintenance staff to a potentially unsafe condition by activating a visual and audible alarm. The WessGuard ® monitor also has normally open contact to tie directly to an energy management system. WESSGUARD ® RETROFIT - TXA Sensor Monitor Sensor Monitor Connection Wt.
