      Cold store - KNV - Klüvers

      On the heat discharge side, the available space for the condensers or dry coolers often plays a crucial role. Noise levels and corrosion must also be taken into account. Klüvers opted for a wall-mounted KVN condenser from Roller with gold lacquered fins which are resistant to the salty sea air.
