York scroll chillers maximise European performance
Published: February 2006
The Tempo range of air-cooled scroll chillers from York offers cooling capacities from 180 to 480 kW and uses R410A. Standard-efficiency models achieve an average EER of 2.74, and high-efficiency units reach 3.1. By introducing multi-scroll configurations to increase full- and part-load performances, these chillers achieve high European seasonal energy-efficiency ratios, which will be part of the European chiller programme during 2006. Leaving-water temperatures can range from 4.5 to 15°C, and down to –10°C with glycol. Tempo chillers can operate in ambient temperatures from –18 to 50°C. The Tempo range includes two low-noise units with options of 2-speed condenser fans and compressor sound enclosure. A specially designed LS model has fans locked into star (slow speed) to reduce sound-pressure levels to 54 dB(A) and 10 m. Other options include an integral Hydrokit with no increase in unit size and active controls to eliminate the need for a buffer tank, power-factor correction, condenser coil protection, high-head fans and a de-superheater to provide hot water at 60°C.
