Fin-and-Tube Heat Exchanger

Our air-conditioning heat exchangers are copper tube fin-type heat exchangers, utilizing high thermal conductivity oxygen-free copper tubes and high quality aluminum foil. The fins are processed through mature pipe bending technology and specially designed high-precision stamping dies. Through stable tube expansion procedures, the core performance of the copper tube fin-type heat exchanger is realized. Every production process of our products undergoes strict quality inspection.

Our products are defined by their functions in customers' air conditioning systems, with common functional classifications including evaporators, condensers, radiators, and surface coolers, among other heat exchanger types.According to the appearance of the heat exchanger, we make the following definitions:
