The GBL heat exchanger is a new type of high-efficiency air heat exchanger. It is produced by scientific and advanced composite technology, so that the 
fins and tubes are closely combined to produce the best heat transfer effect and increase the overall performance of the heat exchanger. It is usually 
the best choice for air heating with high temperature steam or heat transfer oil as heat transfer medium. It has been widely used in chemical fiber, 
textile printing and dyeing, chemical industry, rubber, leather, wood, painting and baking paint, food, plastic PVC, printing, pharmaceutical, 
aquaculture and other industries.
