MIXING VALVE

The mixing valve is a triple redundant, thermostatic pressure balanced valve specifically designed for emergency safety shower/face/eyewash application. The valve is factory mounted and piped to the water heater. The mixing valve meets OSHA and ANSI requirements and is capable of providing 85°F output regardless of inlet pressure and temperature variations, and the temperature setting is tamper proof and can not be inadvertently adjusted in the field. Alternate mixing valve tepid water set temperatures of 70°, 75°, 80°, and 90°F are available.

AUTOMATIC AIR VENT VALVE

An automatic air vent valve is supplied in the highest point of the system to allow trapped air in the system to escape.

DUAL TEMPERRATURE AND PRESSURE GAUGE

A combination temperature (70° - 250° F) and pressure (0 – 200 psi) gauge with 3-inch dial is installed in the tank.

OUTER SHELL AND INSULATION

The tank is encapsulated in 3-inch thick polyurethane foam insulation. The insulation is protected by a high impact non-corroding colorized composite protective jacket.
