The FKN/FKNT series from Roller is a range of ceiling-mounted air coolers designed to meet the special requirements of small, walk-in cold rooms. These popular air coolers are constantly being improved and their models carefully updated. New in the program are now variants with reduced sound values, as well as for flammable refrigerants.
The FKN/FKNT has already been equipped with a pressure-stable and highly efficient EC diagonal fan for years. Some applications have particularly high requirements in terms of noise emission. For these sound-sensitive applications, a quieter version of the EC fan technology has now been developed. The new, quiet FKN/FKNT air coolers with the additional identification ECDS are characterized by a reduction in noise of 4 DB(A) compared to the models still available.
The further development was also an opportunity to develop additional variants for use with ultra-low-GWP A2L refrigerants and flammable/natural A3 refrigerants. For use with CO2, a so-called COG version with an operating pressure of 80 bar is available.
With a depth of only 120 mm, the FKN/FKNT is frequently used in refrigerated rooms in the gastronomy sector, where a wide variety of often mixed open foodstuffs are stored. In order to meet the requirements for correspondingly increased corrosion protection, the evaporator block is provided with a cathodic dip coating on the standard side. The special design of the FKN/FKNT also allows to use the unit both as a wall-mounted and as a ceiling-mounted unit. As a wall-mounted variant, only an easy-to-mount drip tray needs to be attached. Easy cleaning in both installation variants is ensured by a completely hinged housing.
