Autoclave Engineers’ Universal Heater Controller is designed to precisely control temperature on all AE pressure vessels. The controller can be configured to control vessel wall temperature or to control process temperature while preventing excessive temperature at the vessel wall.
The UHC utilizes two independently controlled components (a solid state relay and a contactor) to prevent any vessel over temperature condition. This design ensures that the vessel wall temperature will not exceed safe limits.
Electrical equipment used to control any and all reactor functions.
UHC (Universal Heater Controller) : Process Instrumentation
For control of vessel temperature and protection against vessel wall over-temperature
FEATURES
The Autotune function allows the operator to quickly and easily optimize controller operation to process conditions.
Broken thermocouple indication is displayed on the face of the controller
Controls heaters from 200 watts up to 50,000 watts at applied voltages of 115vac, single phase up to 480 vac, 3-phase.
A simple one step ramp/dwell cycle is included for unattended operation.
The user can change the maximum wall temperature to customize control for each individual process (within vessel limits).
The UHC is designed with circuit breakers instead of fuses so the operator never needs to open the panel. No fuses to stock
BENEFITS
The Universal Heater Controller is designed to control the heating of a pressure vessel based on a Process Thermocouple used as feedback to the
PID algorithm in the PLC Controller.
An optional over-temperature control uses a vessel wall thermocouple to disable the heater if the wall temperature reaches the ASME temperature limit of the vessel (or other user-determined value).
