Klarstein CTR-1 Water Evaporative Cooler 4-in-1 Mobile Air Cooling Unit 65W

Affordable air cooler / fan with air cleaning, humidifying function and three power levels.

Extremely low power consumption with high cooling capacity for medium-sized rooms.

The Klarstein CTR-1 is an elegant and affordable water evaporative cooler that efficiently improves the indoor environment of medium-sized rooms.

The basic function of the Klarstein CTR-1 is an intelligent combination of ventilating and air cooling that delivers a stream of cool air into the room. The cooling of the air is achieved by the evaporation of water / ice from the 8 litre tank. The Klarstein CTR-1 differs from conventional fans as it humidifies and purifies the air in order to improve the indoor environment.

A fundamental advantage of the Klarstein CTR-1 is its superior energy consumption. Despite a low power consumption of only 65W, the Klarstein CTR-1 noticeably refreshes room of up to 50m³. Three power levels and an optional automatic swing motion allow precise adjustment to suit the current weather conditions, room size and preferences.

Another advantage of the Klarstein CTR-1 is the complete elimination of placing restrictions. Mobile air-conditioners require vent hoses to dissipate hot air, and therefore need to be set up near a window. Thanks to the 4 rollers on the bottom of the Klarstein CTR-1, the air cooler can easily be transported to any preferred area.

Furthermore, the Klarstein CTR-1 can be set up in indoor or outdoor areas, and the closing of windows or doors is not necessary.

During operation, little attention needs to be paid to the air cooler. The water consumption is low, at only 1 litre per hour, meaning the device only needs to be filled in the office about once a day. The two supplied ice packs can be used alternately to help cool the air.

Please note that the bottom roller of the device is not mounted. To mount the rollers only takes a few minutes and can be done easily.

A remote control is included to operate the cooler quickly and easily.
