Answer: The inlet temperature is an important technical parameter of the cold dryer. All manufacturers have clear restrictions on the upper limit of the inlet temperature of the cold dryer, because the high inlet temperature not only increases the compressor load, but also increases the water vapor content in the compressed air.
It is generally stipulated that the inlet temperature of the cold dryer shall not exceed. When the exhaust temperature of the air compressor exceeds, a rear cooler must be added downstream of the air compressor to reduce the compressed air temperature to the specified value before entering the post-processing equipment.
