Over 75 years ago, when the refrigeration and air-conditioning
industry was still in its infancy, our company's founder, Wilhelm
Bock, had a vision: he wanted to build first-class and reliable refri-
geration machines. In the following decades Bock developed into
one of the world's leading manufacturers of refrigeration and air-
conditioning compressors.
Today, GEA Bock offers as part of GEA Refrigeration Technologies
the right compressor for all fields of commercial-, industrial-, rail-,
bus- and transport refrigeration.
In this brochure we present you our semi-hermetic compressors for
the refrigerant R134a.
Be inspired. By our new products, our established product series
and the entire passion that goes into each of our products.
GEA Bock - More than a compressor

The F model series provides modern open type compressors for separate drive systems
(using V belts or direct couplings). Load transfer through a V pair.
Virtually all drive capacity requirements can be met.
Very compact compressor design, robust and easy to handle. Oil pump lubrication as
standard.

The GEA Bock HG (Hermetic Gas-cooled) range of semi-hermetic compressors offers tradi-
tional suction gas-cooled compressor state of the art technology. These compressors of the
highest quality standard excel in their running comfort, easy maintenance, efficiency and
reliability. Suitable as standard for conventional or chlorine-free HFC refrigerants.
The HA (Hermetic Air-cooled) range, specially engineered by GEA Bock, is available for
deep-freezing applications, in particular for use with the refrigerants R22 and R404A.

GEA Bock vehicle compressors of the FK range are the result of many years of experience in
the domain of mobile cooling systems.
The unsurpassed light, compact, robust design and wide r.p.m. range are only some of the
outstanding features of this unique product range of two, four and six cylinder compressors.
A wide variety of designs can be tailored to suit individual requirements.
The so-called K version is a special innovation with a unique valve plate system for
maximum requirements in bus and coach air-conditioning systems.

The refrigerant R134aBased on our current semi-hermetic product range, with its outstanding advantages and
features, GEA Bock now presents you a compressor variant optimized especially for the
use with the refrigerant R134a.
Especially suited for normal refrigeration in supermarket applications, as well as in cascade
systems in conjunction with CO2.
Further information see separate brochure "Semi-hermetic GEA Bock compressors".
Special features
With technical optimizations we continually improve the energy consumption of our
compressors. Because of the special design of the different components we can adapt
the compressors ideally to the individual demands. Those compressors optimized for the
specific characteristics of R134a achieve a higher efficiency and therefore increase the
annual capacity of the refrigeration plant.
The refrigerant R134a
Especially in the area of normal refrigeration for supermarket applications numerous
studies have shown that R134a as a refrigerant contributes to a very high efficiency of
the system.
Suitable refrigeration oils are ester oils, such as Fuchs Reniso SE55.
Single-stage compressors R134a
Our solutions are customer-
oriented and user-friendly,
because they are low-priced,
energy-efficient, long-lasting
and tailored to your indivi-
dual needs.

Operating limits
Compressor operation is possible within the limits shown on the
application diagrams. Please note the coloured areas. Compressor
application limits should not be chosen for design purposes or
continuous operation.
Performance data
The performance data for R134a are based on European Standard
EN 12900 with a 50 Hz power supply frequency.
This signifies: 20 °C suction gas temperature without liquid
subcooling
The results in significant differences compared to specifications with
liquid undercooling and/or suction gas temperatures.
Conversion factor 60 Hz = 1,2
Performance data for other operating points see GEA Bock software.

Explanations:
Tolerance (± 10%) relates to the mean value of the voltage
range. Other voltages and current types on request.
- 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
All data are based on the mean value of the voltage range.
