14. OPTIONS
14.1 Water Circuit
Pressure Gauge
The pressure gauge indicates the pressure prevailing at the water outlet and inlet.
Fixed Bypass
The fixed bypass ensures the minimum flow rate in the water circuit. Evaporator and pump in
the closed recirculating system and the single-circuit system are thus protected.
The design of the fixed bypass is project-specific.
Temperature Limit Values
The water temperatures in the water circuit are monitored by limit values. If the preset limit
values are exceeded or not reached, a common fault alarm is issued on the control panel.
Insulation of Water Pipes and Pump(s)
At water temperatures < 12°C, the water pipes and pump(s) have to be insulated. The
formation of condensation water can thus be avoided.
Flow Control Switch
The flow control switch fitted in the water inlet pipe is designed to control the flow rate in the
water circuit. Any time the preset flow rate is not achieved, a common fault alarm is released
and displayed on the control panel via the appropriate error code.
14.2 Electrical System
24 V Remote Control
The process cooler is switched ON and OFF via a 24 V remote control unit. The 24 V signal is
to be connected in accordance with the circuit diagram.
Connecting Cable with plug
The process cooler is delivered ready for plug-in.
