Whenever three or more independent areas of a yacht need to be air-conditioned, this central cooling system is the right choice.   The extremely compact units in the BlueCool C-Series are usually located in the engine room and supply all cabins with pleasantly cool air via a chilled water circuit and air outlets. They cool with an output of 16,000 to 27,000 BTU/h (4.7 to 7.9 kW) and can also heat via a reverse function. Vibration dampers and soft-start accessories are optionally available. Benefits of BlueCool C-Series Highly efficient and quiet The BlueCool C-Series units are very powerful and quiet, even in challenging tropical conditions. Vibration dampers and soft-start accessories increase comfort if required. Easy installation A USB and other interfaces (optional CAN bus) enable simple installation and integration into the boat system as well as fast diagnostics. High-quality epoxy protection Epoxy resin protects the appliance and makes it particularly durable and resistant.
