YORK® YVAA Variable Speed Drive Screw Chiller

Description

The YORK® YVAA Air-cooled Chiller has been proven globally in some of the world’s most challenging conditions. With a patented, liquid-cooled, variable-speed drive that produces 15-25% annual energy savings, IPLV as high as 21.3 EER, and up to 0.25 kW/TR reduction in energy use when replacing existing chillers, YORK® has the experience to tailor and tune the YVAA specifically for you.

• Patented YORK® liquid-cooled, variable-speed drive technology
• Screw compressors designed and manufactured by Johnson Controls
• Patented, stepped VI (volume ratio) technology to match compressor operation to conditions

Benefit:

• Lower annual energy costs
  • Reduce annual energy costs as much as 50% with a liquid-cooled, variable-speed drive for lowest kw/ton at design and off-design conditions.
• Trusted reliability
  • An efficient motor design provides a wide operating range while refrigerant cooling and thermal protection increase compressor reliability.
• Greater value
  • The yvaa can be tailored and tuned to match the capacity, efficiency, sound and footprint of specific applications.
• Optimized design
  • More flexibility and configuration options for maximum performance with a smaller footprint.
