BOGE AIR. THE AIR TO WORK.

BOGE AIR. THE AIR TO WORK.

Over 100,000 compressed air users expect more when it comes to their compressed air supply.

If it is BOGE AIR then you can be assured that it is quality air “Made in Germany.” This not only applies to the first class energy efficient compressed air systems manufactured by BOGE but also to the top quality compressed air treatment products.

BOGE compressed air treatment products have been designed to work in perfect harmony with the compressor range to provide the optimal, most effective and efficient compressed air quality with options available to meet the highest air quality requirements.

BOGE air provides them with the air to work.

Moist compressed air

Dry compressed air

Cooling

Condensate

FUNCTION Warm, moisture saturated compressed air is cooled down to a temperature of +37˚F. The

generous dimensions of the heat exchanger promote especially effective cooling, while flow

resistance is reduced to an absolute minimum.

Contrary to conventional systems the air follows a downward path through the heat exchanger.

The force of gravity results in a particularly high droplet separation of almost 99%. Within the

oversized condensate collection area, the flow velocity is greatly reduced, so the carryover of

previously separated droplets is reliably prevented.

The dried, cold compressed air is re-heated in an air-to-air heat exchanger before being expelled

downstream from the dryer. During this process, the relative humidity of the air is lowered

considerably and up to 60% of the cooling energy is recovered.

Any resulting condensate from the cooling process is discharged from the BOGE RA unit through

the electronic level-controlled condensate drain in order to maximize energy savings. The condensate

can then be safely treated with an appropriate treatment system, such as the QWIK-PURE® oil/water

separation system.

The comprehensive BOGE RA range makes it possible to select a treatment system that is ideally suited to the actual operating conditions.

Efficiency in every detail: The RA series refrigerant dryers.

The BOGE efficiency edge: a total cost comparison shows that reduced pressure losses and low energy consumption ensure a rapid pay back period on the RA series dryers – a clear advantage for both the environment and your investment.

4 BOGE AIR. THE AIR TO WORK.

ENVIRONMENTALLY FRIENDLYThe R134A refrigerant does not have any ozone

depleting characteristics. It is safe for normal

handling as it is non-toxic, non-flammable and

non-corrosive. The BOGE RA dryer has a direct

effect on reducing energy consumption (for

every 2-psi drop saved across the dryer, the

customer saves 1% in energy costs) and

displays maximum respect for the environment

because nearly every component can be

recycled.

LOWEST POSSIBLE PRESSURE LOSS All dryers are characterized by their extremely

low pressure differential due to the downward

path through the aluminum heat exchanger.

This means that the generation pressure

upstream of the compressor can be optimized

and all aspects of the customer’s processes will

run smoother and much more efficiently.

INTELLIGENT DESIGNThe specially-designed aluminum heat

exchanger represents an innovative vertical

profile concept that allows the force of gravity

to result in high droplet separation and

self-cleaning. The BOGE RA series dryer has

a large cross section of flow channels for low

velocities and reduced power input. All

components are time proven and field tested.

RELIABLE PRESSURE DEWPOINTThe all new BOGE RA series dryers are built with

a Varioflow hot gas bypass valve, which utilizes a

special, gas charged capsule that operates

independently of power or electronic support.

This provides users with a 100% stable dew

point, no maintenance, and zero freeze-ups.

Installation instructions To install the standard designed dryers,

the room and/or ambient temperature

may not exceed 122°F and not fall below

40°F. Sufficient clearance must be

provided on all sides of the dryer

to ensure good cooling air circulation.

A suitably dimensioned drainage pipe

must be installed to remove condensate.

Design conditions The flow capacity rate is determined

in relation to the air intake condition

of the compressor (70°F and 14.7 psi):

Compressed air temperature 100°F

(max. 160°F possible), operating

pressure 100 psi, ambient temperature

100°F (max. 122°F possible), pressure

dew point 37°F (higher dew points

possible).

Features: • Varioflow hot gas bypass valve

• Zero loss condensate drain

• Vertical aluminum heat exchanger

Options: • Standard bypass line

• Special voltages

• High pressure

Flow capacity: 10 – 5000 cfm

Refrigerant Dryers RA 10 – RA 5000 Series

5 Compressed Air Treatment | Dryers

The most efficient method of drying compressed air: when compressed air is cooled near to freezing point, water and oil vapors create condensate. This method of drying is expensive for the end user as it uses energy and creates pressure losses. Because of its energy saving components, RA series is capable of substantially reducing such costs over the entire lifetime of the compressed air system by combining savings potentials with maximum reliability.

7 Compressed Air Treatment | Dryers

High Temperature and High Pressure conditions: when compressedair entering the dryer is not ideal, BOGE has the perfect solution. For every 20˚F raise in temperature, you double the moisture in the system. The BOGE RA HT is specifically designed to remove this excess moisture with inlets as high as 212˚F. The BOGE RS HP has specially developed stainless steel heat exchangers and condensate systems to deal with pressures up to 725 psig.
