4-7 DUAL OUTPUT COMPRESSORS (AIR/NITROGEN)
Atlas Copco’s GN Dual
Output compressor generates nitrogen and compressed air simultaneously. Unique
in the industry, the GN is one solution for both air and nitrogen.
The right quality
nitrogen
The GN offers
an assured flow and purity of nitrogen, regardless of changing workplace
conditions. With its integrated membrane technology, the GN provides a constant
flow of nitrogen even in high compressed air use.
Reliable
compressed air
The GN’s
efficient engineering maximizes air flow and reduces energy use, while its
integrated dryer provides quality air to preserve tools and equipment. With the
rotary screw compressor’s low noise operation, the GN can also be installed
close to the point of use to reduce piping costs. With the added assurance of
Atlas Copco’s experienced service team, the GN makes light work of heavy
demand.
The dual
output solution
The GN Dual
Output compressor is the single solution to nitrogen and air production. Fully
integrated and unique in the industry, the GN produces the right quality of
nitrogen and air simultaneously from one compact unit.
Why use nitrogen...
Nitrogen is
proven as a strong alternative to air for tyre inflation in a range of high
performance arenas. Now, inflating road tyres with nitrogen also provides a
wide range of cost and safety benefits for everyday use.
Built-in
reliability
Compressor
1. Rotary screw technology
- The GN’s solid, durable and
quiet 4-7kW rotary screw compressor is suitable for 100% continuous duty
in varying demands
- Rotary screw technology
ensures maximum efficiency with the lowest possible energy consumption.
2. Start/Stop control
The start/stop control feature ensures
that the compressor only consumes energy when nitrogen or compressed air is
produced, saving energy when not in use.
3. Easy access service panel
With service points grouped together for
easy access, the GN also features a screw-on oil separator and filter for
quick, efficient maintenance.
4.
Compressor control dryer
The GN comes
with a clear control panel featuring air delivery pressure, hour meter and dew
point indicator.
5. Fully
integrated dryer
A fully
integrated dryer prevents corrosion in the piping system and tools while
improving the efficiency of nitrogen generation.
Nitrogen
6. Nitrogen
membrane
Innovative
membrane technology separates oxygen from the compressed air and allows
nitrogen to leave the membrane to the point of use.
7.
Integrated filters
Integrated
coalescing DD and PD filters remove any harmful particles and oil droplets from
the compressed air to protect the nitrogen membrane – ensuring long life and
efficient generation. With complete access to the filter area, cartridges can
be replaced quickly and efficiently.
8. Heater
A compact
heater warms the compressed air – ensuring an efficient and constant nitrogen
flow.
9. Nitrogen
purity regulation
The GN is
set to produce nitrogen at a purity of 97%. Nitrogen purities of 92%, 95% and
99% can be obtained with optional regulation nozzles.
10. Control
Panel
A compact,
accessible control panel allows easy monitoring of the pressure drop over
individual filters and nitrogen delivery pressure. Nitrogen purity can also be
shown as an optional extra.
11. Filter
gauge
If pressure
drop over the filters goes above 350 mBar, the nitrogen section will
automatically switch off to prevent the membrane being damaged due to oil
carry-over.
Premium performance
- The GN advantage
Dependable flow
With an
internal heater and a nitrogen membrane designed for each compressor, the GN
provides a constant flow of nitrogen in changing workplace conditions. The GN
also produces a stable flow of compressed air even when producing high levels
of nitrogen.
Assured
quality
The GN
provides the right nitrogen purity even in fluctuating conditions or heavy
compressed air usage.
Minimal
installation costs
With dryers,
filters and nitrogen membrane completely integrated into one unit, the GN takes
up minimal space and reduces installation time and costs. The GN’s low noise
also allows it to be placed right at the point of use. This eliminates the need
for a dedicated compressor room and costly piping to the workfloor.
Low energy
use
Innovative
rotary screw technology offers low energy usage even when producing nitrogen
and compressed air simultaneously – saving costs across the production.
Nitrogen : High performance tire inflation
Minimize fuel consumption
A tyre should be
properly inflated at all times to ensure good road contact. Oxygen molecules
escape quickly through tyre rubber. The resulting pressure loss will affect
fuel use as the tyre loses full contact with the road. Nitrogen stays in the
tyre longer, stabilizing the tyre’s shape to lower fuel consumption.
Improve
tyre life
Compressed
air can create oxidization of the rubber which will increase tyre wear. Air
also escapes easily from the tyre - reducing pressure and creating uneven wear.
As an inert gas, nitrogen doesn’t oxidize the rubber, contributing to longer
tyre life. Because nitrogen does not escape from the tyre as quickly, it
creates a more even level of wear and decreases maintenance.
Increase
safety and driving comfort
Fluctuating
temperatures cause the air inside a tyre to expand and contract – affecting
performance and increasing the risk of a blowout. Nitrogen disperses heat more
easily to keep the tyre cooler. it also maintains the right tyre pressure
longer, minimizing the danger of skidding and improving comfort, handling and
safety even further.
Standard options
- Variable nitrogen purity settings.
- Nitrogen purity indicator.
- Upgrade kits to increase your
nitrogen capacity.
- Nitrogen receivers in various
sizes.
- Oxygen resistant tubes to
remove oxygen from the operating area.
- A line PDx filter to eliminate
particles and fluids.
- Electronic drain option to
remove condensate.
