The CRF 8 Membran pressure compensating tank from Winkelmann is an innovation with high quality and functionality. The tank is suitable for installation in heating boilers and transfers a technology from the automotive industry to heating systems. Instead of a round tank, the CRF 8 is built in a square form, thus ideally using the installation space of the boiler. The CRF 8 is manufactured with a patented PP bubble diaphragm. By using this material and the square form, Winkelmann can fulfil any requirements of its customers. The result: lower maintenance and service cost.
