#Quick installation.

Readily accessible terminal strip for power and control voltage. For freeze protection, a brazed pot on the chilled water line ensures accurate sensing of the water temperature. A heavy duty, multi-wire harness is standard to allow remote installation of the control box. (A five foot harness is standard, but custom lengths are available.)

Interchangeable control boards.

All Marvair chillers and air handlers use the same control board, reducing the spares requirement. It is easily configured for use with our various display/thermostats by simply moving jumpers on the board. The board automatically recognizes what display it is connected to and the appropriate icons are shown on the display.

Control board can be set up for operation with a single or two chillers.

For a two chiller installation, either chiller can be selected as stage one by simply moving a toggle switch. Preset time delays and temperature settings automatically configure that chiller as the second stage. On yachts where more than two chillers are required, multiple modules can be staged to meet the required load. Marvair Marine's unique microprocessor controller coordinates the operation of each module in addition to the seawater and loop pumps. In cases where more than two chillers are required, multiple modules can be staged to meet the required load. Marvair Marine's unique microprocessor controller coordinates the operation of each module.
