Chilled Water Electrical Control Options

Chilled water units have 2 separate controls. One controls the unit itself, and the other controls the Air Handler(s). These systems are all customized; there is flexibility in the design. We recommend you visit one of our Dealers/Distributors for which application will work the best for your yacht. Listed below are the 3 basic types of controls that can be customized for your needs.

Chiller Series

  • MAXX-HZ- also uses the Maxx display, with more customized and programmable options including: frequency drive to control blower noise.
