Variable-speed air compressor

The Quantima variable-speed centrifugal air compressor features oil-free operation and magnetic bearings. The motor and direct-drive compression assembly incorporate the magnetic bearings to provide control both axially and radially of the rotor shaft. Its patented Q-drive compression and motor assembly has just one moving part; it operates with the rotor spinning in a magnetic field at up to 60,000 rpm. Other features include a high-frequency inverter variable-speed drive, high-efficiency inlet air filtration and an acoustic canopy for low noise levels.

Dewpoint transmitter

The DRYCAP dewpoint transmitter DMT152 measures dewpoint in OEM applications down to -112 F. Suitable for use in harsh environments, the compact unit features a polymer sensing technology and comes with a NIST-traceable calibration certificate. Its AUTO-CALIBRATION feature provides dry end accuracy and durability. Applications include air and plastics dryers, dry chambers, pure gases and high-voltage circuit breakers.

Rotary-screw air compressors

The 7500 S-energy Series of lubricated rotary-screw air compressors features energy efficiency system heat recovery. Available in both constant- and variable-speed drive models, the 100-hp compressors offer capacities of 369 to 493 acfm and pressures ranging from 100 to 175 psig. Their air-end design includes a low-restriction air inlet valve, a low-pressure drop air-fluid separation system and a high-efficiency fan. The EES recovers the heat of compression and converts it to recirculating air for comfort.

Oil-injected compressors

The GA range of oil-injected air compressors is equipped with compression elements based on asymmetric rotor profiles to reduce volumetric losses. Radial fans with variable-speed drive regulation, high-efficiency motors and no-loss drains are included in the design to reduce energy consumption. Two elements facilitate air quality: an oil removal system that provides minimum residual oil content in outlet air, and refrigerant dryers, which are available in both integrated and standalone versions.
