The KDC ceiling air cooler creates a pleasant environment for people due the low speed of the air and quiet operation. It has outlet blowers on both sides and is suitable for use in normal cooling as well as low temperature commercial cooling applications. A wide range of application areas, simple installation, easy to maintain and high quality are the features that make this unit the perfect solution for cooling your workspaces.
- Smooth surfaces: Easy to clean
- Optional 45/50 bar CO2/R744 version
- Optional CAL distributor available
- Fans can be operated at a high or low speed
- Guides air along the ceiling so that it spreads further across the room
- Foldable drip tray on both sides allows easy access for cleaning and maintenance
- EC fans deliver significant energy cost savings with long service life
- Draught-free air circulation and quiet operation for a pleasant environment in workplaces
The Kelvion KDC guides air along the ceiling so that it spreads out throughout the room due to the Coanda effect. The Kelvion KDC can therefore achieve top air flow with a very low air speed. Power range from 1.4 kW to 23 kW. The folding drip tray also allows for easy cleaning. All installation parts are easy to access and easy to clean. The fan can be replaced quickly and easily. The drip tray can be removed easily for carrying out maintenance and cleaning activities on the air cooler. Folds out on both sides. If the optionally available condensation water pump is installed, the drainage pipe must not be removed.
