Advantages of stainless steel plate change cold dryer:- The compressed air pipelines are made of 304S stainless steel,which has no secondary pollution to the compressed air and can be applied to the food and pharmaceutical industries.
- The stainless steel,which plate exchange adopts double counter-current design(cold air and hot air exchange,air and refrigerant exchange),so that the temperature of the air outlet is reheated,which can avoid condensation in the outlet pipe.
- 4-18 cubic meters adopts three-in-one stainless plate exchange(heat exchanger,evaporator and steam-water separator),small size , integrated process with good sealing performance,and high steam-water separation efficiency.
The comparative advantages of the high-pressure plate-changing refrigeration dryer and the high-pressure shell and tube refrigeration dryer :
- The heat transfer efficiency is high,the heat transfer coefficient is 2-3 times that of the shell-and-tube machine,the machine has low energy consumption, small size and compact structure.
- Copper brazed stainless steel material,corrosion resistance,no internal leakage point,excellent pressure bearing performance ( currently optional maximum pressure of 45kg);
- The Heat transfer temperature difference is small,the pressure dew point temperature can be as low as 2-3 degrees,and the temperature difference between the dry air at the outlet and the wet air at the inlet is small,which is beneficial to avoid condensation outside the pipe.
- No pressure vessel certificate is required for export to foreihn countries.
