      In many sectors, such as the food industry, the energy sector, logistics, mechanical engineering or building services, cooling is always system-relevant and decisive for the quality of processes and thus of products. As a manufacturer of high-quality components for refrigeration and air-conditioning technology, we know:

      The credibility of the performance data of the machines used is a decisive aspect in ensuring your quality requirements.

      That is why we have the performance data of our products certified by independent laboratories as part of the Eurovent programme. Eurovent is an independent organisation that ensures that the equipment of the participating companies is tested under the same conditions and is therefore more comparable.

      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.
