Oil filter & oil
The high efficiency oil filter provides superior filtration compared to conventional filters resulting in cleaner lubricant. The thermostatic bypass valve ensures that the compressor quickly reaches optimum operating temperature and maintains temperature during periods of low load. The lubricant is specifically formulated to provide limited dilution with hydrocarbon gases and features excellent protection against hydrogen sulfide in the gas stream.

Energy recovery
The energy recovery system consists of a built-in heat exchanger and thermostatically controlled system to recover the heat from the compressor in the form of warm water without any adverse influence on the compressor performance.
