High Capacity Air Conditioning in a compact package

All models offer direct expansion operation in a compact, low-profile unit, with a seawater-cooled condenser and choice of controls. Compact units are designed for installation under a settee or berth, in a locker or cabinet, or other convenient location. Compact systems feature high-velocity (HV) blowers. All blowers are insulated to prevent secondary condensation, and are fully rotatable for flexibility during installation. A stainless-steel chassis is standard on all Compact models. The 30,000 BTU/h model features dual evaporator coils and a single compressor on a single chassis. The dual high-velocity (HV) blowers can be ducted to two or more interior spaces.
