Requiring no professional installation, the compact Alliance 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 Portable is a true air-conditioner, equipped with a flexible exhaust hose to vent via a window. It can thus be taken from room to room, cooling 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 Portable is the perfect answer for economical environmentally-friendly climate control.
