GEA compressors – the best choice for all applications
A compressor design for the refrigerant R744 (CO2)
In this brochure we present our GEA semi-hermetic compressor
range for CO2 solutions in commercial, industrial and heat
pump applications.
GEA compressors – the best choice for all applications
Energy-efficient, sustainable technologies are rapidly gaining
importance for operating industrial and commercial refrigeration,
air-conditioning and heat-pump-systems. Growing public
awareness and new climate / environmental protection standards
promote cleaner, eco-friendly energy sources. This makes high-
efficiency products and cooling systems using alternatives, such
as natural refrigerants, more viable.
GEA offers comprehensive expertise and equipment for natural
refrigerants, including ammonia (NH3 / R717), carbon dioxide
(CO2 / R744 subcritical and transcritical), and hydrocarbons
(HC / R290, R1270). The company offers the world’s largest
compressor range for natural refrigerants. GEA’s portfolio
incorporates a full range of refrigeration technologies:
• Reciprocating compressors
• Screw compressors
• Plug & play compressor units
• Chillers and heat pumps
• Valves
• Control panels
The company’s products and solutions meet today’s leading
energy efficiency and environmental protection standards:
• ASERCOM certification: GEA complies with strict energy-
efficiency requirements for compressors.
• BREEAM certification: GEA compressors and chillers increase
performance ratings in accordance with this leading sustainability
assessment method for infrastructure and buildings.
• Ecodesign Directive: GEA offers a large range of products that
are compliant with this design directive.
• F-gas regulation: GEA supports the european and globel
inttiatives to ban F-gases and prevent the greenhouse effect by
using natural refrigerants with a low GWP (global warming
potential).
Natural refrigerants are gaining ground
The focus here is mainly on our compressors that are suitable
for the use of the natural refrigerant CO2. GEA offers compressors
that are developed for the use with CO2, not only with regard to
pressures, but also in many other respects. This includes a robust
design for the partially demanding operating conditions with
CO2, a very smooth and quiet operation due to low vibration and
pulsation, a very low oil carry over and a unique energy
efficiency level. The GEA series of CO2 compressors meet all
requirements of the F-gas regulation. Thus, they can be used
for long periods and increase the planning dependability for
system manufacturers, users and investors.

Since 2006 the F-gas regulation (EC) No 842 / 2006 has been
governing the use of fluorinated hydrocarbons (HFC) in
technical refrigeration systems. The reason why emissions into
the atmosphere must be kept within limits is that the heat-
absorbing properties of HFC represent a cause of the greenhouse
effect and global climate warming.
Since the beginning of 2015, the new F-gas regulation EU
517 / 2014 is effective. Planners, manufacturers, implementers
and operators of refrigeration systems must undergo considerable
reorientation. The new directive narrows their choice of applicable
refrigerants more than ever, marking a fundamental turn away
from refrigerants with a high greenhouse effect.
F-gas regulation – HFC on the way out
The goal set for the year 2030 is to reduce emissions of partly
fluorinated hydrocarbons (HFC) to a fifth of the average output
2009 – 2012. Already in the near future, equipment for
refrigerants with high greenhouse potential will be banned
from the market, and refilling of existing systems will be
subjected to restrictions.
As a technology partner for refrigeration, air-conditioning and
heating applications GEA offers comprehensive advice and
support for your switch to the natural refrigerants ammonia
(NH3), carbon dioxide (CO2), and hydrocarbons (HC / R290).
An extensive portfolio of compressors is available for any task.

CO2 system examples
The refrigerant CO2
Within refrigeration technology, carbon dioxide (CO2) is known by the name
R744 and has a long history. lt is a colorless gas which liquefies under pressure
and has a slightly acidic smell and taste. Carbon dioxide has no ozone depletion
potential (ODP = 0) and a negligible direct effect on global warming (GWP = 1)
when used as a refrigerant in closed systems. It is non-combustible, chemically
inactive and heavier than air. Carbon dioxide has a narcotic and asphyxiating
effect on humans only at higher concentrations. As carbon dioxide has
a weakness at higher temperature in energy efficiency compared to other
refrigerants, we concentrate on optimizing plants to close these gaps, e.g.
with the implementation of parallel compression and ejector technologies.
Single-stage applications
Single-stage transcritical CO2 applications are used in the field of medium-
temperature refrigeration. They can be operated very efficiently if the high
pressure is operated in the subcritical range over a long period. Using the high-
pressure side, it is appropriate to use the application in the transcritical range
also in combination with refrigeration, due to a big temperature glide and a
relatively high discharge end temperature for specific heat pumps and the
heat recovery. Transcritical GEA CO2 compressors are used.
Cascade application
In a cascade system, different refrigerants are used in an application. They
are combined in two refrigerating circuits that are separate from each other.
A solution with CO2 in low-temperature refrigeration is very interesting due
to economic reasons and the perspective of efficiency. The high-temperature
stage is used as a condenser in the CO2 application. Here it is possible to use
different refrigerants like hydrocarbons, ammonia and also HFCs like R134a.
Subcritical GEA CO2 compressors are used in the low-temperature stage. In the
high-temperature range there is a wide product portfolio of GEA compressors
available for the use of different refrigerants.
Booster applications
Regarding applications with CO2 in low and medium temperature refrigeration,
so-called booster systems are used. High pressure of low temperature
compressor is discharged directly to the suction side of the second compressor
stage. Different plant constructions of these booster applications are used, for
example, in supermarket applications. Transcritical and subcritical GEA CO2
compressors are used.

GEA offers a variety of compressors for commercial and industrial cooling or heat pump
applications for use with CO2 as a refrigerant. What these compressors have in common
is that they are optimized for use with CO2 not only with regard to pressures but also in
many other ways. Relevant features include a reliable design (to meet the challenges of
CO2 operation), very smooth running thanks to low levels of vibration and pulsation, quiet
operation and low oil carry-over. The design engineers have also made provision for good
thermal separation in the compressor, to the benefit of high efficiency.
The HGX34 CO2 T (4 cylinders) and HGX46 CO2 T (6 cylinders) series of transcritical CO2
compressors can achieve efficiency performance data unrivalled by any other comparable
product on the market, boasting the highest EER/COP values within the wide application
limits. This efficiency is verified by certification of the performance data at several
displacement stages by ASERCOM. Available in various model sizes, the transcritical
CO2 series cover a wide range of swept volumes from 6.2 to 38.2 m3/h (at 50 Hz) and are
designed for operating pressures up to 130 bar.
The portfolio includes the HGX12e CO2 (2 cylinders), HGX22e CO2 (2 cylinders), HGX34e
CO2 (4 cylinders) and HG4 CO2 (4 cylinders) series for subcritical CO2 low-temperature
applications, offering a range of swept volumes from 1.6 to 48.2 m3/ h (at 50 Hz).
The whole range is applicable for variable speed drive. With subcritical CO2 compressors
supporting an frequency range from 25 or 30 to 70 Hz and transcritical CO2 compressors
(4 and 6 cylinders) supporting 20 to 70 Hz, these series are able to cover a very wide
performance range, providing refrigeration capacity that is flexible enough to adapt to
prevailing requirements.

CO2 compressors for the refrigerant R744
CO2 compressors transcritical
Since the beginning of the 1990s, GEA has been engaged in
the development of compressors for transcritical CO√ systems.
The series now covers displacement from 6.2 to 38.2 m3/h (50 Hz)
with 2-, 4- and 6-cylinder reciprocating compressors. The
compressors are distinguished by high reliability, excellent
operating performance, a wide frequency band for minimum
part-load needs and efficiency standards previously unachievable
in the market.
The collected outstanding performance data has also been confirmed
officially through ASERCOM (Association of European Refrigeration
Component Manufacturers). Therefore, the compressors contribute to
lowest life-cycle costs and comply with long-term legal requirements
such as the F-gas regulation in Europe.
The compressors are used in transcritical and subcritical applications
for supermarkets, industrial refrigeration and heat pumps.

CO2 compressors subcritical
For low-temperature applications a series with displacements
from 1.6 to 48.2 m3/h (50 Hz) is available. This series offers the
advantages of a time-tested compressor series that has been
optimally adapted to the demands of CO2.

Oil pump • Optimal oil circulation• Oil pressure control (optional)
Motors for variable speed drive • 30–70 Hz (2-cylinder)• 25–70 Hz (4-cylinder)
With technical optimizations we continuously improve the energy consumption of our
compressors. The compressors of the e-series set a new standard when it comes to
motor-efficiency, gas flow and efficiency of the valve system. All this results in a higher
refrigerating capacity of the compressor at a lower drive power.
The compressors are used in cascade and booster systems
in supermarket and industrial cooling applications.

TECHNICAL DATA – SUBCRITICAL CO2 COMPRESSORS
Explanations
1) Tolerance (± 10%) relates to the mean value of the voltage range. Other voltages and current types on request.
2) • The specifications for max. power consumption apply for 50 Hz operation. For 60 Hz operation, the specifications have to be multiplied by the factor 1.2. The max. working current remains unchanged.
• Take account of the max. operating current / max. power consumption when designing contactors, leads and fuses.
• Switches: Service category AC3
3) 220-240 V ∆ / 380-420 V Y - 3 - 50 Hz, 265-290 V ∆ / 440-480 V Y - 3 - 60 Hz
4) 380-420 V Y/YY - 3 - 50 Hz PW 440-480 V Y/YY - 3 - 60 Hz PW
PW = Part Winding, motors for part winding start (no start unloaders required)
• Winding sectioning: HGX4 CO2 = 66% / 33% • Designs for Y/∆ on request
6) For soldering connections
7) The maximum permission working current of the compressor (Imax com) must not be exceeded. Take account of the guidelines for use of frequency inverter in the compressor assembling instruction.

Read facility via INTelligence diagnosis softwareWith the INTelligence software, valuable information can be obtained on the status of the compressor and the system. The diagnosisfunction includes the plausibility checks of the logic sequences, all important operation and error values of the compressor, and itprovides clear visualization. Crucial evaluation parameters can be configured individually. This allows for a quick analysis and an efficient system management.
Advantages:
• Simple operation
• Immediate diagnosis and precise problem solving
• Specially adaptable to the user’s needs
If required, data can be retrieved directly at each compressor via USB port. A Modbus interface is available for integration into a network. The data is sent periodically via the DP-Modbus gateway and the Modbus-LAN gateway to a server and can be retrieved remotely by the INTelligence diagnosis software. The INTelligence diagnosis software can be downloaded for free at www.kriwan.com.
