Key Benefits
  • Simple to install and highly reliable
    This chiller offers easy installation, application flexibility, high reliability and optimized energy efficiency due to its direct-drive compressor design that uses fewer moving parts than gear compressors.
  • Precise temperature control
    Our chillers are uniquely suited for both industrial and commercial applications that require precise temperature control while also eliminating the need for expensive buffer tanks.
  • Compact size reduces installation challenges
    Chiller replacement is faster, less expensive, and less disruptive due to it is compact size, it easily fits into most existing mechanical rooms without requiring additional floor space or wall tear-outs, most units can pass through a standard door opening.
