ATS has designed and manufactured a new range of refrigerated compressed air dryers that provide a combination of technology and performance.

FUNCTIONALITY PRINCIPLE

The warm compressed air enters the air/air heat exchanger and becomes pre-cooled by the outgoing cold air. Secondly, the pre-cooled air passes through the evaporator where it is cooled to the required temperature. Thirdly, the condensate, separated from the compressed air in the demister, is discharged automatically by the condensate drain. Finally the refrigerant and the temperature are regulated by a by-pass pressure valve.

Main features
• Low pressure drop
• High technology ultra-compact aluminum heat exchanger
• Easy maintenance
• Oversize components

ULTRA COMPACT HEAT EXCHANGER

The main component of the refrigeration air dryers is the heat exchanger. This compact aluminium unit contains various stages of the treatment of compressed air.

AIR / AIR EXCHANGER

Where the first phase is carried out. In this section the inlet air is pre-cooled and the outlet air is post- heated. This allows the reduction of energy consumption of the chiller circuit and reduces the possibility of condensate forming on the outer surface of the outlet pipe.

FLOW MIXING CHAMBER

Unlike other exchangers on the market, the unit designed has a flow mixing chamber at the air/air exchanger outlet. This passage is very important because the air temperatures at the exit of the air/air exchanger channels are not uniform. The mixing chamber enables the air flow to enter the evaporator channels at a uniform temperature, allowing an optimum exchange.

EVAPORATOR

The air cooled in the evaporator passes through a demister separator which allows the condensate to drain into a large collecting chamber. The design of both module and demister allows pressure drop values to be kept low.
