Roller extends air cooler options

GERMANY: Roller has extended its range of ceiling-mounted air coolers with low noise and flammable refrigerant variants.

The FKN/FKNT series models for small, walk-in cold rooms have long been equipped with pressure-resistant and highly efficient EC diagonal fans, but even quieter versions are now available with EC fan technology for applications with particularly high demands on noise emissions. The new air coolers with the additional designation ECDS achieve noise reductions of 4dB(A) compared to standard models.

The series also now includes further variants for use with ultra low-GWP A2L refrigerants and flammable A3 refrigerants. A so-called COG version with an operating pressure of 80bar is available for use with CO2.

The FKN/FKNT, which is only 120mm deep is often used in refrigerated rooms in the catering trade, in which a wide variety of foods, often open, are stored together. In order to meet the requirements for a correspondingly increased corrosion protection, the evaporator block is provided with a KTL dip coating as standard. 

The special design of the FKN/FKNT also allows the device to be used as a wall or ceiling device. As a wall-mounted variant, only an easy-to-install drip tray needs to be attached. The easy cleaning in both installation variants is guaranteed by a completely hinged housing.
