Cuddly warm room temperatures or a refreshing breeze: with the oneConcept CTR-1 Heat 4-in-1 air cooler and heater you get the perfect airflow 365 days a year. The smart mobile device combines four functions: air cooler, fan, humidifier and heater all in one.

As a mobile fan, the oneConcept CTR-1 Heat continuously emits a powerful air flow to the room and helps the body's own temperature regulation in an uncomplicated manner. Even if it is not actively cooling the air, it still provides refreshment. With 3 fan speeds and operating modes, it can respond to individual refreshment requests and achieves an air throughput of up to 360 m³ per hour. In a very natural way, it can also cool the air flow as an air cooler for even more freshness. For this, water is evaporated from the 8-litre tank into the air flowing through it. This cools the air flow purely physically and ensures pinpoint refreshment regardless of whether you are at the desk, on the couch or at the kitchen table.

When the days are getting shorter and the demand for heat is increasing, the oneConcept CTR-1 Heat does its job as a powerful heater. It then heats up the air flow in two stages with powerful 1300 or 2000 watts and thus provides cosy warmth. It also works well as a humidifier in winter and provides relief to troubled mucous membranes when the heated air is dry.

All functions can be called up quickly and easily using the remote control or the LED-supported operating section. The four floor rollers make the CTR-1 Heat fully mobile to bring it to any desired location in the home or office.

Ready for use 365 days a year - four smart functions make the oneConcept CTR-1 Heat air cooler an all-rounder when it comes to fan technology.
