air-to-air heat exchanger

air-to-air heat exchangerProduct Overview:
The SRZ and SRL spiral fin radiators produced by our factory are mainly used for air heating in drying systems and are the main equipment in hot air devices. The heat medium used in the radiators can be steam or hot water, or thermal oil. The working pressure of steam generally does not exceed 0.8Mpa, and the temperature of hot air is below 150 ℃.
The finned radiator of an air heat exchanger is mainly composed of three rows of parallel spiral finned tube bundles in the air flow direction. The processing technology of the SRZ type finned tube bundle is to mechanically wrap a 0.5 × 10mm steel strip around an 18mm seamless steel tube, and then hot-dip galvanized. It can also be made of stainless steel tube and stainless steel strip to form a fully stainless steel radiator. The SRL type radiator is a finned radiator rolled from steel tube and aluminum strip, with a larger heat dissipation area per unit length than the SRZ type.
Due to the use of mechanical winding, the contact surface between the heat dissipation fins and the heat dissipation tubes is large and tight, with good and stable heat transfer performance and low air resistance. Steam or hot water flows through the steel tube, and the heat is transferred to the air passing between the fins through the fins tightly wound on the steel tube, achieving the effect of heating and cooling the air.
