Did you know?

The GZ oil-free compressor was the first application of an oil-free gas compressor in the Carrier LNG (CLNG) market. The oil-free design offers the user a lower OPEX cost due to the compressor's extended service life and lack of oil filtration equipment

Built for high efficiency

The Variable Speed Drive (VSD), coupled with inlet pressure control, maximizes flow and minimize required horsepower. By working less to do more, VSD consumes less power, while giving greater process control and requiring less maintenance

Low cost of ownership

Implementing gas screw technology and VSD drive, the GG-Series offers you tremendous savings in terms of energy and maintenance. Well-designed circuits, full accessibility and the capability for predictive maintenance also contribute to a low cost of ownership for your machinery

Oil-free operation for zero contamination

GZ compressors can handle tank pressure control, fuel supply or liquefaction duties without any risk of oil carryover or contamination.
