The general dew point of the dryer is 2-10°C, which is the temperature of the evaporator section, because if it decreases further, the condensed water will freeze, creating ice gambling, destroying the operation of the equipment and the circulation of compressed gas.
However, in fact, the gas temperature of the dryer is excluded from 20-30°C, because the compressed air passes through the pre-cooler after exiting the evaporator. The low-temperature gas exchanges heat with the gas just entering the dryer, thereby improving the performance of the dryer. Outlet temperature.
The key issue is that the purpose of cold-drying machines is not to be cold, but to be dry. Excluding air drying is the performance of cold-drying machines.
Of course, this is not an unresolved solution. We can recommend the appropriate dryer for the customer based on the temperature requirements of the customer.
