GRF Marine Water-Cooled Screw Compressor
The marine workhorse cooled by sea or fresh water, built for continuous nitrogen-feed, instrument and service air duty.
Overview
Engine rooms are hot and compact; water cooling carries compression heat away through sea or fresh water, holding discharge temperature steadier and improving reliability over air cooling for continuous duty. The GRF water-cooled range covers 22–250 kW with three-stage oil separation below 3 ppm — down to 2 ppm on two-stage machines — protecting downstream nitrogen-generator adsorbent. Pressure parts are selected and surveyed to class rules, with material certificates, test reports and class documents supplied.
Key features
Sea/fresh water keeps discharge temperature steady in hot engine rooms.
Three-stage separation < 3 ppm; two-stage down to 2 ppm.
CCS / BV / RS / ABS held, coverage across 10+ society rules.
Available as a complete skid with dryer, filters and receiver.
