The limited number of heat exchanger applications for Roll-Bond is due to existing methods of manufacture. New technology has been developed to change this. By bonding and inflating coils rather than short pieces, continuous Roll-Bonding increases design flexibility. Very long lengths, lighter gauges, straight tubes or groups of tubes are now possible in addition to conventional silk-screened patterns. Greater productivity makes the new product more economical and combinations of continuous Roll-Bond with alcladding and brazing are especially interesting possibilities when designing cost effective, high performance heat exchangers.
