TWBS.SHE – Thermostatic Mixing Valve

Model TWBS.SHE, lead-free Emergency Valve (patent pending), thermostatically mixes hot and cold water to provide a safe fluid supply for emergency shower and eyewash equipment. The valve contains a secondary high temperature limit valve to provide additional protection to the user in the event of main tempering valve malfunction. Additionally, to ensure a fail-safe water supply for emergency shower and eyewash stations, a series of cold water by-pass valves open in the event of hot water pressure loss. (No gauges supplied – ASSE 1071 standard recommends gauges be placed 5 to 8 feet (1.52 to 2.44 m) downstream for the most accurate temperature measurement.)

TWBS.HF – Thermostatic Mixing Valve

Model TWBS.HF, lead-free Emergency Valve (patent pending), thermostatically mixes hot and cold water to provide a safe fluid supply for emergency shower and eyewash equipment. The valve contains a secondary high temperature limit valve to provide additional protection to the user in the event of main tempering valve malfunction. Additionally, to ensure a fail-safe water supply for emergency shower and eyewash stations, a pressure sensing diverter valve is provided that sends a pressure signal to open the cold water by-pass valve in the event of hot water pressure loss, main valve thermostat malfunction, or clogged cold water check-stop. (No gauges supplied – ASSE 1071 standard recommends gauges be placed 5 to 8 feet (1.52 to 2.44 m) downstream for the most accurate temperature measurement.)

TWBS.EW.H – Instantaneous Water Heater

Model TWBS.EW.H An on-demand, prepackaged, fully engineered and tested tempering system to provide tempered water instantaneously. System is designed to increase cold water temperature by a minimum of 19° C at 15.1 L flow and 38° C at 7.5 L; thus it is suitable for single eyewash application. Outlet water temperature is factory set at 26° C.

9201EW – Thermostatic Mixing Valve

Model 9201EW Emergency Valve thermostatically mixes hot and cold water to provide a safe fluid supply for a single emergency eye/face wash. Additionally, to ensure a fail-safe water supply for emergency eyewash stations, a cold water by-pass valves open in the event of hot water pressure loss. (No gauges supplied – ASSE 1071 standard recommends gauges be placed 5 to 8 feet (1.52 to 2.44 m) downstream for the most accurate temperature measurement.)

CSA Certifies this product to perform according to the ASSE 1071 standard and applicable sections of CSA B125.3.

9400LPS – AXION® Low Pressure Steam Water Heater

The Haws 9400LPS AXION® Low Pressure Steam Water Heater replaces hot water tanks when pressurized steam is available. When an emergency shower or eyewash is activated, the flow of water opens a steam control valve. The steam enters a brazed plate heat exchanger, instantly heating the water. An ASSE 1071 certified mixing valve blends hot and cold water to produce an output of 80® F (27® C ) tepid water. Additional valves keep the system preheated, freeze protected and scald protected. The steam valve will remain closed should there be a loss of water pressure.
