This document summarizes the features and specifications of BOGE refrigerant dryers models ED 3 through ED 137. The dryers use a heat exchanger and integrated separator to maintain a consistent pressure dew point. They include controls for the dryer and compressor operations and a pressure dew point display. Larger models have an air-cooled condenser while smaller models have a static condenser for cooling without additional fans. Specifications include flow rates, pressures, electrical requirements, connections and dimensions for each model.

1. CONTROL
A user friendly control is equipped with an
on/off switch, LED displays for dryer and
compressor operation, and a LED bar
graph display for the pressure dew point.
FULLY AUTOMATIC VALVE
A check valve is designed to proportionally
control the flow of the refrigerant into the
heat exchanger according to the air volume
flow. The R134a and R407c coolants ensure
environmentally friendly operation.
AIR COOLED CONDENSER
Extremely large cooling coils means that
the condenser is able to work effectively
and efficiently even in the most adverse
conditions to cool the saturated compressed
air – for maximum operational safety.
CONSISTENT PRESSURE DEW POINT
The stainless steel 3-in-1 heat exchanger
with integrated separator assures a consistent
pressure dew point under differing ambient
conditions. The low pressure differential ensures
high quality compressed air.
1) Heat exchanger with integrated separator
2) Compact design low corrosion galvanized
steel housing
3) Air cooled condenser (ED 23 - ED 137 only)
4) Control valve for proportional refrigerant
flow into heat exchanger
5) Compressor
Installation instructions
For the standard dryers, the room and/or
ambient temperature may not exceed +49°C
(ED 3 - 17) or +43°C ED 23 - 137), and not
fall below +4.4°C. The refrigerant dryer should
have sufficient free space around it in order
to ensure satisfactory cooling air circulation.
A sufficiently dimensioned drain pipe is
required to take away the condensate.
Design conditions
The max. inlet temperature is +55°C
(ED 3 - ED 17) or +58°C respectively
(ED 23 - ED 137).
Features:
• Dew point bar graph display (ED 3 - ED 40)
and/or LED display (ED 53 - ED 137)
• Timer controlled condensate drain
(except ED 3: type Float)
• Coolant R134a (ED 3 - ED 27)
and R407c (ED 40 - ED 137)
Options:
• Standard bypass line

AMBIENT TEMPERATURE
The design feature of the ED 3 - ED 17 series
is the static condenser which allows the
dryer to be air cooled irrespective of variable
ambient temperatures (see conversion factors).
STATIC CONDENSER
A static condenser means the ED 3 - ED 17
series is air cooled working reliably without
any additional fan or energy consumption.
