This water-cooled screw compressor chiller (120 to 190 tons) features sound pressure levels from 74 to 76 dBA at one meter, per ASHRAE Standard 575. According to the company, the chiller's single main rotor compressor is quieter than conventional twin screw compressor designs and eliminates the need for sound attenuation equipment as well as sound-proofing mechanical rooms. The chiller, which is 35 inches wide to fit through 3-foot-wide doorways, has part-load ratings as low as 0.536 kW/ton IPLV, states the manufacturer. The MicroTech II™ direct digital controls with the Protocol Selectability™ feature allow integration with most building automation systems using LonMark®, BACnet®, or Modbus® communications without the need for costly gateway panels, the company says.
