Chaper 2: Functional Description
2-1 Introduction
Open Resevoir water temperature control units are reliable, accurate, and easy-to-use process
temperature control units. They are self-contained, portable, and shipped ready to use.
The water temperature control unit is designed to circulate water through your process and to
precisely, automatically, and reliably maintain it at a specified temperature. Standard unit
operating range is from 0ºF (-17ºC) to 180°F (82°C). The unit is suited for use with city
water, water from portable or central chillers or towers, or well water.
These units are designed for rapid recirculation of a relatively small amount of water to
provide close and uniform temperature relation between delivery and return lines. This
performance, of course, depends on the configuration of your process and any restrictions
within the mold. The recirculation, combined with the large immersion heater and cooling
capability, gives fast and accurate response to bring the water up to temperature or to changes
in the settings when needed.
The Open Resevoir water temperature control unit is a self-contained system consisting of a
centrifugal pump, electric immersion heater, cool/vent solenoid valve, and electrical control,
including a PID microprocessor controller and thermocouple. It is designed for use in process
temperature control applications using water or a water/glycol mix. Any other use or fluid is
prohibited.
Some standard safety devices include a mechanical overtemperature safety thermostat, a
pressure relief valve, motor overload protection, a low pressure cutout switch, branch fusing,
and non-fused lockable rotary disconnect.
A properly installed, operated, and maintained temperature control system provides years of
reliable operation. Please read and follow the
instructions in this manual to get the most
satisfaction from your Open Resevoir system.
