Energy
Efficiency |
|
Energy efficient operation remains of
paramount importance with regard to any
industrial machine and the process it
supports. With the introduction of Buran
cycling refrigerated air dryers with
Ultrapulse technology, Ultrafilter has
made a major stride in reducing the
power required to dry and filter
compressed plant and process air. |
| |
|
Real-World Operation |
|
Standard refrigerated air dryers are
designed to operate around a set of
fixed conditions regardless of actual
dryer load, changes in ambient
conditions, or the needs of the process
the dryer supports. In real-world
applications this results in inefficient
operation, unnecessary power consumption
and higher operating costs. |
|
|
|
Intelligent Design |
| The components of
Buran cycling dryers have been designed,
specified and integrated to take
advantage of new developments in
compressor life, heat exchanger design,
computer control and real-world
operating conditions. |
|
|
|
Intelligent Control |
| Ultrafilter’s
Ultrapulse control technology not only
cycles the dryer’s compressor on and off
in reaction to load changes, but also
tracks and then proactively anticipates
load trends and adjusts the cycle
accordingly. This control logic avoids
dew point spikes (sudden increases in
dew point beyond acceptable limits)
commonly associated with cycling dryers. |
|
|
|
Intelligent Operation |
| The combined outcome
of intelligent design and control is
intelligent operation. Buran dryers with
Ultrapulse technology provide the user
with three modes of operation –
Standard, Summer and Flex – giving the
highest level of flexibility at the
lowest possible energy consumption, while
maintaining the required level of
compressed air quality. |
|
|
|
Refrigerant Compressor |
| Lower quality
refrigerant compressors cannot tolerate
the on-off cycling that often results
from changing loads on a dryer. Standard
dryers utilize a hot gas bypass valve
which allows the compressor to run
continuously regardless of load. While
this avoids a reduction in the life of
the compressor, it results in
unnecessary power consumption relative
to actual load as the compressor runs
continuously. |
|
|
|
Buran dryers are built with the latest in high quality compressors whose service
life is not shortened by power-reducing cycling. This has allowed for system
designs that take advantage of the fact that most dryers are not required to
operate at full capacity all of the time. The hot gas bypass valve is no longer
needed and an operating cycle has been developed that turns the compressor on
and off based on the actual load. This in turn provides the user with lower
operating costs through reduced power consumption. All Buran cycling dryers use
environmentally safe R134a refrigerant. |

Trisab
Heat Exchanger |
|
Buran dryers (models SD 0050 AP-60 through SD 1000 AP-60) are built with
Ultrafilter’s proven TRISAB heat exchanger technology and take advantage of its
aluminum mass for energy storage. The ability to store and use cooling energy
adds to the power efficiency of Buran cycling dryers. |
| |
| TRISAB is a
three-stage aluminum block heat
exchanger with integral pre-cooling of
the process air, final cooling to the
required dew point, and internal
condensate collection. |
|
|
It incorporates these additional features:
- Large heat exchanger surface area for rapid heat transfer
- Large smooth flow channels for very low pressure drop and energy
conservation
- Discharge air is reheated as it pre-cools incoming process air,
preventing pipe sweating and lowering energy consumption
- Corrosion resistant aluminum construction
- Condenser cooling air flows through front of dryer and out at the top
allowing for flexibility in dryer location |
