The Therm-O-Mix® is designed to supply tepid water delivery for one shower/eyewash combo at a time. This water heating system should be installed in close proximity to the shower and piped into a facility’s steam and cold water supply lines.

When an emergency shower or eyewash is activated, the pressure drop on a diaphragm opens the steam control valve (V-3). Water and steam flow are established instantly heating the water and condensing the steam. After exiting the heat exchanger, the hot water enters the tempering valve (V-5) and then the mixing valve (V-1) where it is blended with cold water to produce an outlet of 80°F water. The steam valve remains closed should the water supply be interrupted.

Typical Applications

OSHA and ANSI require all your emergency fixtures to provide tepid water for a minimum & continuous 15-minute cycle. Tepid is defined to be between 60°F (16°C) and 100°F (38°C). The Therm-O-Mix® Tepid Water Delivery System can ensure your emergency equipment will meet these code requirements by providing 80°F water to protect personnel from scalding or freezing temperature. Since the station does not require any electric power, it is suitable for explosion-proof environments and outdoor installations.
