【new structure】 most of the fin-tube heat exchangers used for clean gas use a new and efficient fin surface structure. 【strong economy】this heat exchanger uses conductive materials, so it is very economical from heat transfer to cooling. 【energy-saving effect】this heat exchanger will automatically heat the water to a preset temperature. during this process, no electricity is needed, so it can have an energy-saving effect. 【wide range of applications】power, chemical, petrochemical, air-conditioning engineering and refrigeration engineering, etc. 【note】copper pipes need to be forged at a high temperature and then cooled with water during the production process. some water stains will inevitably occur during this process, but it will not affect the normal use of the heat exchanger. if you mind this, please consider carefully before buying
