Axion® Low Pressure Steam Water Heater

Brand: Haws Corporation
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. This 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. 

This station complies with the ANSI Z358.1 standard and mixing valve is designed to meet ASSE 1071

Prop 65 Warning. For California Residents Warning: This product contains a chemical known to the State of California to cause cancer and/or birth defects or other reproductive harm.
Features
  • Flow Rates: Provides 3 to 25 GPM (11 to 95 LPM) of tepid water.
  • Operation: Low pressure system operates on typical plant steam pressure, 15-30 PSIG (1-2 BAR) is recommended. Steam and water never mix, separated by brazed plate heat exchanger.
  • Designed to meet ASSE 1071 Requirements: Unit employs a paraffin filled thermostatic mixing element with the lowest internal pressure drop where supply pressure is low. The modular brass design with a one piece casting uses internal check stops, oversized valve seats, a shuttle design that eliminates valve sticking, and a funnel design to improve temperature control with better mixing at low flow rates.
  • Installation: Ease of installation, uses existing plant steam and water supply. Union connections are provided for quick installation. Compact, lightweight design, easily supported by pipe connections.
  • Servicing: Durable, protective enclosure can be readily removed for servicing.
  • Medically Superior Response®: AXION’s superior design and technology provide a complete safety solution for increased victim comfort.
