Air Dryer Brazed Plate Heat Exchanger Low Energy Consumption

 

Detailed Product Description

 
 

Air Dryer Brazed Plate Heat Exchanger Low Energy Consumption

The heating surface consists of thin corrugated stainless steel plates that are compressed together to

form a plate pack. Channels are formed between the plates and the ports are arranged so the media

flows through alternate channels in full counter current flow. Media is directed by a brazed seal enhanced

with contact points to contain the media flow pressure. Convenient location of air in- and outlet on the same

side. Water is separated at the coldest point and then exits through a drain.

Features and advantages

Low energy consumption due to the very low pressure drop over the heat exchanger.

Excellent thermal performance.

Two combined heat exchangers, consisting of both the air to air heat recovery and air to refrigerant.

Integrated connection with heat recovery that requires no additional piping.

Convenient connection locations.

All refrigerant connections are on one side, air and water drain on the opposite side.

Stainless steel for reliability and long life.

Compact: The corrugated compressed plates significantly reduce the total air dryer size

 

Refrigerated air dryers separate humidity from compressed air by cooling the air in an evaporator. This cooling 

effect comes from the evaporation of the refrigerant. As the air cools,  it looses its ability to hold moisture. The 

condensate is then collected and removed in a separator.

A heat recovery air to air heat exchanger that reheats the air to ambient temperature is in the dryer for optimal 

efficiency.

The coldest temperature in the system determines the "dew point". "Dew point" is the temperature at which the 

water vapor in the air starts to condense in the water separator.

This is normally maintained slightly above the freezing point of water,  2-5 °C (35-40 °F).

The humid air enters into the heat exchangers and cools down in the air to refrigerant. This humid air then moves 

into a separator and then dry air is preheated in the heat recovery side. The total air side pressure drop is typically 

20-30 kPa (3-4 psi)
