DD Series – Delpet Dryers

Overview
Delpet Series Compressed Air Dryers are specially designed for PET Bottle manufacturing process. Compressed air is used to blow the bottles/containers to the desired shape and size.

How Does it Works

How does it work?

Delair Refrigeration Dryers operate at high pressure upto 40 bar on the method of cooling the air to near freezing point to remove the moisture and the cold dry air is reheated by incoming air to approximately 10°C below the incoming compressed air temperature at nominal conditions.

 

The dryer consists of an air drying unit with centrifugal cum demister pad condensate separator and a refrigeration circuit. The refrigeration circuit consists mainly of a compressor, a condenser, a receiver, a vapour liquid accumulator with liquid refrigerant and an evaporator.

The air drying unit consists of two kinds of heat exchangers, one is air to air heat exchangers and second is refrigerant to air heat exchangers.
