Did you know? Flat ceiling air coolers in the commercial refrigeration/freezing sector are called DLK/T at Roller. The more powerful versions were presented as NEXT units.

For these, a new generation of EC fans (optional) is being launched, which provides information via Modbus in a cloud, e.g. on the operating status and current speed, and enables load-dependent control. As the current back pressure can also be used to draw conclusions about the tyre condition of the evaporator block, precise defrosting on demand is now within the realms of possibility.
