More than 15 years of experience in the use of compressors for CO2
CO2 is becoming an increasingly important refrigerant in commercial
refrigeration technology worldwide
Special demands on efficiency and reliability
Customers from more than 30 countries attend CO2 training courses
SINDELFINGEN, Germany, July 8, 2013 /CNW/ - For more than 15 years, the BITZER group of companies has been building
up its experience in the development and manufacture of compressors for
the refrigerant CO2 and now offers a comprehensive range of products for subcritical and
transcritical applications. The first subcritical BITZER system in the
USA has been running reliably and failure-free for five years.

The importance of CO2 refrigeration systems for subcritical and transcritical applications
has risen in recent years and is set to keep rising. However, this
growth has been at different speeds in different places, with Northern
Europe and Australia taking the lead. BITZER turned its attention to
this technology early on - launching products on the market to meet
different requirements and constantly developing them. Their market
share is growing not only in Europe but also in North America.
Supermarkets equipped with CO2 refrigeration systems
With its product portfolio, BITZER is among the established suppliers in
the USA. Five years ago, they commissioned their first subcritical CO2 refrigeration system in a supermarket in Saratoga Springs, New York.
The first system to feature transcritical CO2 compressors made by BITZER in the North American market has been up and
running in a Canadian shopping mall for more than three years.
This system has been working fault-free ever since it was manufactured,
an achievement that requires close cooperation between project partners
during the planning, commissioning, and service phases. BITZER provides
its partners with its global experience in the use of compressors, and
it advises and trains customers in how to use compressors for
subcritical and transcritical CO2 applications. In addition to our experts at our headquarters in
Germany, application technicians in Canada, the USA, and Mexico are on
hand to provide quick and expert assistance on location. Our
compressors for subcritical and transcritical CO2 applications have UL certification, and as of this year our SL
compressors are also being manufactured in Oakwood, Georgia. Production
of compressors for transcritical applications is scheduled to begin
there at the end of the year.
Compressors for subcritical and transcritical CO2 applications have to meet special safety, dependability, and efficiency
requirements because of the particular characteristics of CO2 itself. Thermal loads, high operating pressures, and high specific
refrigerating capacity combine to produce considerable forces and
burdens on smaller components. BITZER has developed new standards over
recent years in connection with subcritical and transcritical operation
and by meeting requirements in the adaptation of its compressors'
Aside from being reliable, it also crucial that compressors are
efficient with regard to energy. When it comes to assessing the
environmental compatibility of alternative solutions, it is not just
the primary CO2 emissions caused by escaping refrigerant that have to be taken into
account; indirect emissions caused by the consumption of energy also
have to be considered. BITZER compressors have reached a very high
standard in this respect - one that is now considered a benchmark in
the industry, as confirmed by ASERCOM certification, which so far only
BITZER's SL compressors have received in the CO2 application field. The Association of European Refrigeration Component
Manufacturers is a conglomerate of leading European component
manufacturers in the heating, ventilation, air-conditioning, and
refrigerating technology sector.
As well as developing and manufacturing CO2 compressors, BITZER focuses on comprehensive customer training. Regular
training courses using functioning systems are held in its CO2 training centers in Rottenburg (Germany), Sydney (Australia) and São
Paulo (Brazil). In Rottenburg alone, around 550 people from more than
30 countries have attended these courses since November 2010. The
teachers provide both theoretical and practical basic knowledge about
how to work with CO2 as a refrigerant. In the practical part of the course, they conduct
highly realistic instruction on commissioning and troubleshooting in
connected systems incorporating several evaporators. In addition to
that, the teachers cover specific topics relating to BITZER products
and CO2 applications.
Implementing a new technology in the market requires a balanced approach
consisting of a comprehensive range of products, outstanding system
characteristics, expert advice, and sound training. CO2 is one of many examples of this in the BITZER product portfolio.
The BITZER Group is the world's largest independent manufacturer of
refrigeration compressors with sales companies and production sites for
reciprocating, screw, and scroll compressors as well as pressure
vessels all over the globe. In 2012, 3,046 employees generated sales of
