Cash Acme, 24639, HeatGuard 3/4' Tank Booster Pro with Corrugated Hose and Integral ChecksCash Acme Tank Booster is a Temperature Actuated Mixing Valve that mixes hot water with cold to deliver tempered water at a controlled temperature to 120°F (49°C).The Tank Booster is intended for installation at the water heater to distribute controlled temperature water through hot water systems in residential and commercial applications. The valve delivers water at 120°F (49°C), allowing the heater to be set at 140°F (60°C) or higher, thus providing a greater effective volume of hot water and reducing the chances of Legionella bacterial growth in the water.It features a robust design based on the expertise gained from years of experience in the design and manufacture of safety valves. Every valve is tested for performance on an automated testing station during the assembly process. The valve is third party listed for distribution applications.The Tank Booster incorporates a fast-acting, high quality thermostatic element that senses the outlet water temperature and reacts to maintain a stable delivery temperature even under changing flows or variations in supply temperatures. The valve also greatly reduces the outlet flow in the event of a cold water supply failure.The Tank Booster is factory set at 120°F (49°C), but can easily be adjusted.The Tank Booster is designed for easy and quick installation and is shipped complete with the valve, flexible connector and water heater tee. Can be used with SharkBite flexible water heater connectors for easy installation while using Copper, PEX, or CPVC tubing. Does not require any transition fittings.Features:Precise temperature control: Safer hot water from all outlets.Allows the water heater to be set at 140°F (60°C) or higher: Greater effective hot water volume and less chance of Legionella within the cylinderEvery valve is tested for performance prior to shipping: Specify and install with confidence!More hot water from the same water heater: Higher storage temperature means a greater effective hot water volume delivered at a safe 120°F (49°C).Robust, low complexity construction: Superior reliability, improved user safety.Adjustable and lockable mechanism: Minimizes unauthorized tampering with valve setting.Factory set at 120°F (49°C) Listed by IAPMO and ASSE: Inspector friendly, peace of mind.Integral recirculation portAllows quick and neat installations in systems with recirculation.
