EWTC Thermoregulator Range
The Eaton-Williams range of Thermoregulators has been designed to provide close temperature control for plastic/rubber injection mould tools, extrusion barrels and other industrial processes that require accurate heating/cooling.
The heart of each unit comprises of solid state relay controlled immersion heaters and an indirect heat exchanger to provide process cooling. The use of solid state relays for heating element control ensures quiet, reliable and long life operation. Process fluid circulation is by immersible centrifugal pump providing constant pressure and flow rate. The process temperature is continually monitored and regulation of better than ±1°C is achieved by a micro-processor controller with proportional, integral and derivative control in both heating and cooling modes.
There are 7 model sizes in the Thermoregulator range from 9 to 72kW heating capacity. Models up to 24kW are suitable for water or synthetic oil. Also available is a high temperature water unit up to 160°C
The controller has an easy to read red LED display for the process temperature
with the process set point displayed below in green. Red LED arrow indicators
show whether the unit is in heating or cooling mode.
All the Thermoregulators are supplied set with optimum PID loop settings to suit most applications, however all parameters are fully adjustable. For oil applications, the controller can be re-rogrammed to give 30% power output on a short cycle time to control heating element film temperature, ensuring the oil does not carbonise.
Set point limitation is built into the controller programming.
The units are designed with service/maintenance in mind. The EWTC 09, 18 and 24 units have a hinged top cover for easy access to the filling pipe (for oil based systems), the manual auto-fill inhibit valve and for checking pump rotation.
The side and end panels can be easily removed for servicing of the main components such as the pump and solenoid valves.
