Oil tempering units

6 to 75 kW heating power

The oil tempering unit is designed as a stand-alone unit for a duty cycle of 100%. The tempering unit can also be controlled by an external controller using the provided interfaces. If necessary, application-specific control parameter sets and additional, customer-specific logical control tasks can be integrated into the unit’s software. 

Additional functions (optional):

•      Two permanently stored temperature PI control parameter sets (“dynamic” and “slow-
•      External preselection and switching of PI control parameter sets (“dynamic” and
•      Bypass valve between flow and return flow lines for quick limiting of heating power
•      Additional heat transfer oil connection in flow and return flow lines for optional pre-
       tempering of oil
•      2-point controller function for oil pre-tempering
•      4-line control panel with function and cursor buttons for specifying setpoint and dis-
       playing actual value of oil
•      Relay output for optional setpoint valve for oil pre-tempering
•      PT100 analogue input for measuring actual value of oil temperature
