Requiring no professional installation, the compact Alliance R410A Portable can be taken home and installed within minutes. Unlike room coolers that rely on the evaporation of water to reduce air temperature - which increases humidity - the Alliance R410A Portable is a true airconditioner, equipped with a flexible exhaust hose to vent via a window. It can thus be taken from room to room, cool in Summer and heating in Winter. It also removes up to 1.2 litres of water per hour, exhausted via the exit hose, thus dehumidifying your environment. For the home or small office, the Alliance R410A Portable is the perfect answer for economical environmentally-friendly climate control.
