York Chiller Motor Provide Maximum Chiller Efficiency On the Job

The industrial age ushered in a period of energy extraction based on the principles of combustion – heat and steam were integral to the process. On the other hand, York chiller motors take advantage of heat exchange, compression, and continuous, condensed flow of cold energy. To achieve maximum efficiency, entering condenser water temperatures (ECWT) target load points including the cooling tower and fan motor.

Single-stage compressor design contains fewer parts which minimizes downtime when accessories need to be repaired or replaced. Design elements incorporate high strength aluminum-alloy and airfoil shaped pre rotation vanes in support of low load management.

By both operation and design, York chiller motors reduce energy costs, keeps installation costs low, and reduces field labor costs with minimum piping and wiring during set up. Solid-State Starter and other units driven by Variable Speed are powered up through three leads transferring energy to the chiller and peripheral parts.

Critical to operations is the precise control of compressor oil pressure. The old-fashioned fixed head and bypass oil pressure control approach disallows adjustments while the chiller is on. Just with air flow, continuous oil flow to the compressor is aided by the variable speed drive oil pump. Low-voltage adaptive capacity control independently adjusts motor speed and compressor pre-rotation vane position, analyzing information fed into the chiller sensors.

Displacement powers handle all load conditions while the variable speed provides smooth drive line acceleration, soft start, and sound level reduction. Key features include over-voltage and under-voltage protection, overtemperature protection, and digital readout.
