Cash 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 deg F (49 deg 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 deg F (49 deg C), allowing the heater to be set at 140 deg F (60 deg C) or higher, thus providing a greater effective volume of hot water and reducing the chances of Legionella bacterial growth in the water. The Tank Booster is a high quality mixing valve incorporating the latest in thermostatic technology. 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 deg F (49 deg 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.
