Structure and features: 1.often used for convection heat transfer of steam - steam, steam - liquid, liquid liquid; waste-heat recovery; vapor condensation and liquid evaporation 2.has two detachable channels for cleaning 3.made by two steel rolling, forming two uniform channels for counter-current flowing of two medium, so greatly enhances the effect of heat transfer. heat exchange area(m2)channel spacing(mm) 1m/ceshandling capacity of1m/ces flowm3/hConnection pipe diameter modelweight(kg)I 6BI 6B typeI 16BI 16B type163.8940I 6,I 16B1-0.2/300-64450263.8940I 6,I 16B2-0.2/400-67885468.250I 6,I 16B4-0.4/400-61311351017.380I 6,I 16B4-0.5/450-101291331013.770I 6,I 16B4-0.4/500-10161205868.2150I 6,I 16B8-0.4/500-62122151017.380I 6,I 16B8-0.5/550-102352731020.9080I 6,I 16B8-0.6/500-102372751068.2150I 6,I 16B10-0.4/600-62953551017.380I 6,I 16B10-0.5/650-103154051020.9080I 6,I 16B10-0.6/600-1030539515612.5470I 6,I 16B15-0.6/600-64154901017.380I 6,I 16B15-0.5/760-104055751028.180I 6,I 16B15-0.8/600-104005701439.3100I 6,I 16B15-0.8/700-145056802068.2150I 6,I 16B20-0.4/800-6540710
