There are 37 specifications of SRL type air heat exchanger, which is composed of steel tube and aluminum fin tube bundle. Therefore, the aluminum fins are in close contact with the steel tube, with good heat dissipation performance and reliable use.

The SRL type air heat exchanger uses steam or superheated water as the heat medium, with a high steam pressure of 8Kg/cm2 and a superheated water temperature of 160 ℃. It is suitable for air conditioning systems and air heating in drying rooms.

The SRL type air heat exchanger is arranged in two rows of pipes and three rows of pipes in the direction of the air flow. The model examples are as follows:

SRL-5 × 5/2- Two rows of pipes arranged in a cross pattern along the direction of airflow.

SRL-5 × 5/3- Three rows of pipes arranged in a cross pattern along the airflow direction.

The heat transfer coefficient and resistance of SRL type air heat exchanger are shown in the following table
