Compressor protection

The compressor is protected by the following devices and their combinations:
1 Pressure switch: this switch stops the compressor when the discharge pressure exceeds the set value.
2 Oil heater: this band-type heater protects against the formation of foam on the oil during cold starts and remains enabled when the
compressor is at a standstill.
