YORK YCAV0457 — 440-Ton Class Air-Cooled Screw Chiller
The YORK YCAV0457 brings four independent refrigerant circuits and four variable-speed twin-screw compressors to the 440-ton rental class. The Style A S / P platform uses R-134a and a 266-gallon direct-expansion evaporator with 10-inch chilled-water connections. Its standard water-flow range is 350–1,250 GPM. Factory engineering drawings, complete technical data and the installation, operation and maintenance manual are included below.
Estimated equipment rental only. Delivery, taxes and applicable fees quoted separately. Final pricing confirmed with dispatch.
