The Ultima series compressors from Gardner Denver are the smallest, quietest and most efficient twostage variable speed dry screw compressors on the market. Each airend is individually driven by a variable speed, permanent magnet, water-cooled motor operating at >97% efficiency. This makes Ultima a true direct-drive compressor, completely eliminating the gearbox and its associated energy loss. The intelligent on board controller (Digital Gearbox™) continuously adjusts the speed of each airend independently, delivering the perfect speed ratio that provides up to 13% better efficiency than the competition. Ultima has up to a 37% smaller footprint than competitive machines thanks to water cooling and the elimination of the gearbox. The patented control methodology completely eliminates the need for an inlet valve and the associated pressure drop and maintenance requirements. The fully enclosed water-cooled package offers industry leading noise performance as low as 63 dBA. The GD Pilot XTC™ 8” touchscreen controller provides a user friendly state-of-the-art interface that allows data logging and sequencing capability*. Ultima is truly a revolution in oil-free compressor technology from Gardner Denver.
