Quantech has expanded its line of QTC4 Air-Cooled Variable-Speed-Drive Screw Chillers to a total of 21 models ranging from 150 to 360 tons. With the expanded line, Quantech officials said many models are in-stock ready to ship within three to five days to enable immediate chiller replacement.
The company claims its QTC4 line (150-360 tons) employs advanced variable-speed technology to deliver market-leading part load efficiency (IPLV or NPLV) while meeting or exceeding ASHRAE 90.1-2013 full load efficiency standards. The variable-speed drive capability enables 25% to 50% energy savings. It also dramatically cuts sound levels at off-design conditions by up to 16 dBA. An advanced hybrid falling-filling-type evaporator and microchannel-type condenser optimize heat transfer and minimize the refrigerant charge.
