Kelvion KDC


The KDC replaces some long standing product lines from the group including the Goedhart FC38D, Küba DP and the Searle DSR ranges which have over 50 years combined operation in the market. The Kelvion KDC provides gentle cooling and quiet operation for sensitive produce and/or area’s where people are working. The dual discharge air coolers are suitable for high, medium and low temperature applications in the commercial refrigeration sector. Better performance, easy installation, serviceability and high quality make this unit the perfect fit for your working area needs.

Draught-Free air movement and silent operation

The technical cooling demands and spatial conditions are only one aspect. Safety and health are top priority as soon as people need to work in cold rooms. For staff to perform their work without adverse effects their wellbeing must be assured. Noise and air movement in such rooms are a significant contributing factor to a pleasant indoor climate. The demands made on equipment to ensure a constant temperature in rooms where sensitive goods such as cut flowers are exhibited for sale and where people also need to work of course, are high. Draught-free air movement and extremely quiet operation create a pleasant indoor climate for the people and excellent conditions for the processing and short-time storage of sensitive products. The air in the room is drawn in by the fans and exhausted via the heat exchangers on both sides. The Kelvion KDC guides the air towards the ceiling where the Coanda effect carries it far into the room. The Kelvion KDC in this way creates optimal air flow at very low air velocity. Power ratings range from 1.4 kW to 23 kW. The drip tray hinges down to facilitate comfortable cleaning.

Easy installation and maintenance

All mounted parts are easily accessible. Cover plates and drip tray can be removed and mounted again quickly and easily. The use of bolts is reduced to a minium. The fan can be replaced with a flick of the wrist. The drip tray can be removed to inspect and clean the air cooler. It can be hinged on both sides. When the optionally available condensate pump is installed, there is no need to dismantle the drain pipe.
