The QTC4 Air-Cooled Variable Speed Drive Screw Chiller line includes 21 models from 150-360 tons. All models meet or exceed ASHRAE 90.1-2013 full load efficiency standards and deliver highly efficient part load operation.
The variable speed drive enables a 25-50% savings on energy and reduces sound levels at off-design conditions by up to 16 dBA. A hybrid falling-filling type evaporator and a microchannel type condenser optimize heat transfer and minimize refrigerant charge.
