Compressor Protection
The compressor is protected by the following devices and their combinations.
1. High Pressure Switch: This switch cuts out the operation of the compressor when the discharge pressure exceeds the
setting.
2. Oil Heater: This band type heater protects against oil foaming during cold starting, as it is energized while the compressor
is stopped.
