3.18 Liquid injection valve kit (optional)

3.18.1 Operating logic

In order to reduce the exhaust temperature of the Road compressor, the liquid injection valve injects liquid

into the suction line.

As soon as the compressor discharge temperature reaches 100°C (230°F), the thermostat installed on

the compressor discharge line opens the injection valve to lower the exhaust temperature and protect the

Road compressor.
