GRF Marine Air-Cooled Enclosed Screw Compressor
The blue canopy is the air-cooled build: low noise and integrated control for retrofits and space-restricted positions.
Overview
The air-cooled enclosed package seals compressor, cooler and control system inside a sound-attenuated canopy. No cooling-water system is needed, so installation is more flexible — particularly on retrofits where water piping is hard to route. The GRF air-cooled range covers 7.5–110 kW; the canopy lowers running noise and access doors simplify routine service. Recommended for ambient up to 45 °C with good engine-room ventilation.
Key features
No water piping needed — more flexible on retrofits.
Lower running noise improves the engine-room environment.
Controller and protection built in, simple wiring.
Well-placed service doors for routine maintenance.
