Refrigerated Air Dryer Manufacturer

 

• The aluminum plate fin structure provides a larger heat exchange area, allowing for efficient heat transfer within a compact size.
• Compared to traditional shell-and-tube heat exchangers, the aluminum plate fin design is more compact and saves space.
• Easy maintenance and longer component replacement intervals help reduce long-term operational costs.
• Seamlessly integrates with different compressor models and industrial equipment.

 

 

♦ Good heat exchange performance, saving refrigeration energy consumption

The heat exchange performance of the aluminum plate-fin heat exchanger is much greater than that of the conventional shell-and-tube heat exchanger. The air inlet and outlet temperature difference can reach 2℃, reducing the required refrigeration capacity, thereby saving the energy consumption of the dryer.

 

 

♦ Large heat exchange area

Aluminum plate-fin heat exchangers are made of multiple layers of corrugated fins and partitions. The fin spacing is very small and the number of layers is large, so the heat exchange area is large and the heat exchanger structure is compact.

 

 

♦ Stainless steel wire mesh filtration separation

The air-water separation of aluminum plate-fin heat exchangers is mostly done by stainless steel wire mesh filtration separation, which has the advantages of simple structure and high air-water separation efficiency. Stainless steel wire mesh is generally made of SST304 material, which is strong and corrosion-resistant.

 

♦ High-end and efficient refrigeration accessories

The models with a processing flow rate of ≤13.5Nm³/min use a constant pressure expansion valve design, and the models with a processing flow rate of ≥17m³/min use a capillary tube as a throttling device design, which has strong reliability, ensuring a continuous supply of refrigerant inside the evaporator, and a constant evaporation temperature of 2-3℃. Shanghai Fengshen/Danfoss/Emerson hot gas bypass valves are used to ensure that there is no icing in the system.

 

♦ Automatic cooling water regulation

Danfoss WXF series water flow regulating valves are used to automatically adjust the cooling water injection amount according to the refrigerant pressure inside the dryer to ensure constant pressure stability of the system and stable compressor load.

 

♦Three-dimensional optimization design reduces welding points of refrigerant pipelines

As shown in the three-dimensional figure below, the refrigerant inlet and outlet evaporator interface has been replaced by a locking process instead of welding. After years of optimization design, the welding points of the refrigerant external circulation pipeline have been reduced to 5. Compared with the shell and tube refrigeration dryer, which has more than a dozen welding points, the probability of refrigerant leakage is extremely low.
