TECHNICAL DATA SPECIFIC TO J / K COLLECTOR

These collectors are designed for use with J Series tanks, and are only suitable for connection to a closed heat exchanger circuit. When filled with Solahart "Hartgard" solution in accordance with the installation instructions the collector is suitable for use in frost areas. The absorber is made from two sheets of steel, with press formed fluid ways and headers. The formed steel sheets are bonded together by a resistance welding process, steel collector sockets are MIG welded to the assembled absorber plate.
