Chapter 1: General Information
1-1 Introduction
MICRO Series 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 MICRO Series 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 250°F
(121°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 MICRO Series water temperature control unit is a self-contained system
consisting of a centrifugal pump, electric immersion heaters, 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 cut-
out switch, branch fusing, and non-fused lockable rotary disconnect.
A properly installed, operated, and maintained MICRO Series system provides
years of reliable operation. Please read and follow the instructions in this manual
to get the most satisfaction from your MICRO Series system.
