e state, this heat exchanger is particularly need longer in hot runner, the process conditions, the use of conventional heat exchanger area and the volume is very big. HANZUN thread plate condenser is based on the requirement of the extended the condensing trip, without any increase in investment of heat exchange area and equipment volume are greatly decreases, and big limit to ensure the solvent recovery.?Second, the enrichment system?In medicine, chemical production, to concentrate processin
