How a Marine Chiller System Works
Marine chiller systems - also known as chilled water A/C systems - are a great choice for boats with several cabins. If three or more independent areas in a yacht need to be air-conditioned, a central marine chiller system is the right choice.
The chiller unit is placed in the engine room, providing chilled water or glycol to all cabins via a chilled water circuit. Air handlers are fitted in each cabin providing the required cooling capacities to the rooms. The system offers one control for the unit itself as well as separate panels for each cabin.
