The frictionless centrifugal compressor chiller operates as low as 0.375 kW/ton IPLV, and its full load performance is as low as 0.62 kW/ton. The compressor design reduces sound levels because the magnetic bearings eliminate the metal-to-metal contact noise of conventional bearings, the company says. Sound pressure ratings are as low as 77 dBA, per ASHRAE Standard 575. The chiller requires less than 5 amps to start and uses R-134a. The MicroTech II™ controls with the Protocol Selectability™ feature allow integration with a building automation system using BACnet®, LonWorks® or Modbus® communications.
