Installation instructions
To install the standard designed dryers,
the room and/or ambient temperature
may not exceed 120°F and not fall
below 35°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 14.7psi):
Compressed air temperature 95°F
(max. 140°F possible), operating
pressure 100psi, ambient temperature
80°F (max. 120°F possible), pressure
dew point 38°F.
Options:
- Standard bypass line
- Water cooled
- Multicel plug and play installation
Flow Capacity: 800 - 4000 cfm
SOLID PERFORMANCE
With the Introduction of BOGE’s new Digital
Scroll refrigerated air dryers, the bar has
been raised and a new performance
standard has been set for Cycling dryers.
The user no longer has to accept dryers
with a large, heavy footprint, circulating
pumps, unpredictability and uncontrollable
Dew Points as found in typical cycling dryers
utilizing 30 year old technology. The BOGE
Digital Scroll is 40% lighter and 32% more
efficient than typical thermal mass designs.
FLEXIBILITY AND CONTROL
BOGE’s Digital Scroll is a truly energy
efficient dryer design that provides the
precise dew point control that industrial
processes demand. The Digital Scroll is
available in SingleCel modules ranging from
800 scfm to 2000 scfm and Multicel
models ranging from 2500 scfm to 4000
scfm offering total installation flexibility to
meet your specific needs.
DIGITAL SCROLL TECHNOLOGY
The Digital Scroll operates in two stages -
the "loaded state", when the solenoid valve
is normally closed and "unloaded state",
when the solenoid valve is open. During
the loaded state, the compressor operates
like a standard scroll and delivers full
capacity and mass flow. However, during
the unloaded state, there is no capacity
and no mass flow through the compressor.
It provides variable capacity output from
0% to 100% seamlessly.
END USER BENEFITS
The Digital Scroll has more consistent
performance during load variations and fan
cycling to prevent freeze-ups. Because of this
the dryer can maintain a steady pressure dew
point at all loads, thus ensuring dry clean air
at the point of use. That, coupled with a small
footprint and lightweight design makes the
Digital Scroll appealing in all applications.
Energy Efficient Cycling Refigerated Air Dryer:
BOGE’s new Digital Scroll is a
truly energy efficient dryer design that provides precise dew point control
that industrial processes demand. The Digital Scroll is used in both heavy
industrial to high technology environments. There is true, sustainable
energy savings with capacity control between 0% - 100% and models
ranging from 800 to 4000 scfm.
