Marvair® Chillers
Models CHA24, 36, 48 & 60
Marvair reverse cycle chillers are currently built in cooling capacities of 24,000, 36,000, 48,000 and 60,000 BTUHs.
The CHA models feature:
- Two cabinets and footprints. For boats going to tropical climates the chiller can be upsized without redesigning the engine room
- 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 feet foot, heavy duty, multi-wire harness allows remote installation of the control box.
- Ease of service. Six strategically positioned screws allow the top, the front and left side panel to be easily removed all from the front of the unit. Refrigerant valves and the flow switch can be accessed without removing the manifold.
- Interchangeable control boards. All Marvair chillers and air handlers use the same control board, reducing the spares requirement. The display automatically determines whether it is connected to a chiller or air handler and displays the appropriate icons and information.
- 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
- Superior Components. Coaxial tube-in-tube cupronickel sea water heat exchanges and stainless steel flat plate chilled water heat exchanger. Rugged, easily accessible paddle type flow switch. To ensure years of dependable performance, all components are housed in a superior corrosion resistant aluminum cabinet.
- Environmentally friendly R410-A refrigerant.
- CE compliant
The CHA chillers can operate in a standalone application or when
additional capacity is required, the chillers can be staged.
Accessories include:
- Pump kits
- Controllers
- Air handlers
