An ideal climate with rooftop air-conditioning The smallest models of the Cool Top Trail family are suitable for use in parked motorhomes and caravans of up to 8 m length. With their generously sized heat exchangers they have a high efficiency and high performance. Their reliability and high cooling capacity has already been proven in very hot Australian summers with up to 50 °C outside temperatures. The units come with heat pump function as a standard which is also very powerful, working in cold outside temperatures of as low as -5 °C. Very low noise levels allow you to rest and relax inside the vehicle and do not disturb your neighbors in the RV campsite. The use of high-quality components ensures a long lifetime with a minimum expenditure on maintenance. Made from UV stabilized polypropylene, the housing of the units is robust but still lightweight. The units can be operated with an easy to handle remote control which allows the user to access all air conditioner functions from the comfort of the dining area, seat or bed. Besides cooling and heating the units include various extra features such as dehumidification, timer and sleep function. Cool Top Trail air conditioners are delivered with a mounting frame for roof openings of 400 x 400 mm. For the use in smaller cut-outs of 360 x 360 mm an alternative adaptor frame is available as accessory.
