BL26 series Refrigerated Air Dryer Excellent Thermal Performance for Air to Air
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
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
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
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)
