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.
OPTIONS
The following optional features may be included in your water heater. Reference included drawing specific to
your heater for further details.
Low Temperature Alarm Dry Contacts
A low temperature thermostat is available with dry contacts to remotely alarm when the tank water temperature
falls below a specified setpoint. The low temperature thermostat is adjustable from 30-110°F.
High Temperature Alarm Dry Contacts
High temperature alarm dry contacts are available with the optional immersion high limit cut-out switch to
remotely alarm when the tank water temperature rises above the high limit setpoint.
Outdoor Weather Package
The optional outdoor weather package includes a 304 stainless steel outer protective jacket, a weather resistant
electrical housing, and 6” high tank legs to raise the entire unit off the floor.
Flow Alarm
An optional flow alarm may be included to signal that there is tepid water flow.
Explosion Proof Construction
The system may be constructed for installation in a hazardous location.
Mixing Valve Enclosure
An optional fiberglass enclosure provides added protection for the mixing valve in outdoor environments.
Multiple Units
Multiple units may be piped together to meet the needs of larger demand systems.
Alternate Heat Sources
An optional heat exchanger may be factory installed to utilize steam or boiler water as the heating source.
