Q70L Variable Speed Centrifugal Compressor

The two-stage variable speed centrifugal Quantima provides unmatched efficiency due to its low level of energy consumption and it’s incredibly low off load power consumption. At 400 HP, the Quantima off-load power is 2.5% of full load power or 7.5 kW while comparable compressors have an off load power of 15 to 70% of their full load power. These off load power savings, along with better efficiency result in up to 25% lower energy consumption when compared to a two-stage variable speed oil-free rotary screw compressor. This lower energy consumption can translate into annual energy savings of $10,000/year or more.

The design of the Quantima features only one rotating part suspended in air by a magnetic field. There are no rotor timing gears, no gearbox to drive the compression stages and therefore no oil required for lubrication. As a result, there is no oil or oil filter to replace and dispose, providing significant savings on maintenance costs. With standard rotary dry screw technologies the airend elements have a limited life span and will lose performance over time and may require replacement in as little as 40,000 hours of operation. For a plant that operates 24/7 that can occur in just 6 years! The elements can cost upwards of $50,000 not to mention the labor and downtime to install them. Quantima does not lose performance over time, and will not require an element change to maintain efficiency. This translates into savings of up to 25% on maintenance costs.

The Gardner Denver Quantima Series compressor designs feature high-quality, sound-insulating enclosure panels and a vibration-free design. These features reduce the sound levels and eliminate the need for a separate compressor room, saving money on installation costs and providing installation location flexibility
