Our Roots
BITZER’s history is part of our identity. It shows where we come from, what we stand for, and what continues to shape us today. Drawing on more than nine decades of experience, we look to the future without losing sight of our roots.
Since 1934
Our beginnings
It all starts in Sindelfingen, Germany, in 1934 when the company is founded by Martin Bitzer. The first BITZER compressors are reciprocating compressors with co-current flow design.
Company founded in Sindelfingen, Germany, by Martin Bitzer
“[…] and when we look back today, we do so with gratitude. We have always been supported by employees whose dedication, extending far beyond their duty, helped us overcome difficulties.”
2-cylinder reciprocating compressors in an open design
Another milestone in compressor technology follows in 1940: 2-cylinder reciprocating compressors in an open design. First, we develop types I to IV, and due to their success, we expand our product range to include types V to VII.
BH Hermeta series
Our product portfolio in 1954 includes the BH Hermeta series – a new design of hermetic motor compressors with drive power of up to 0.75 kW.
Semi-hermetic suction-gas-cooled reciprocating compressors: BHS series
By 1959, we have expanded our factory five times. BHS semi-hermetic suction-gas-cooled reciprocating compressors with drive power of up to 10 kW are now part of our range – a trendsetting innovation at that time.
Ulrich Schaufler takes over the company
Ulrich Schaufler takes over the company in 1961.
Expansion and relocation of our site in the center of Sindelfingen
In 1965, our site in the center of Sindelfingen once again becomes too small. In order to be able to continue growing, we start building new premises on Eschenbrünnlestrasse – which we move into in 1966.
Semi-hermetic 4- and 6-cylinder reciprocating compressors with drive power of up to 30 kW
In 1972, we expand our series to include semi-hermetic 4- and 6-cylinder reciprocating compressors with drive power of up to 30 kW.
The portfolio of shell and tube condensers and liquid receivers grows
In 1976, our portfolio of shell and tube condensers and liquid receivers is growing. We had already started developing and producing them back in 1950.
Since 1979
The Start of a New Era
In 1979, Ulrich Schaufler’s son, Senator h. c. Peter Schaufler, takes over the company with 270 employees. His vision: to make BITZER a leading international company.

“Diligence, a spirit of innovation, and quality rooted in tradition – these are BITZER values brought to life by our employees. They are our greatest asset.”
Revolutionary: semi-hermetic open drive screw compressors
The market launch of semi-hermetic open drive screw compressors in 1983 is revolutionary. At that time, screw compressors represent the pinnacle of compressor manufacturing in the industry.
The global expansion begins with BITZER Australia
The global expansion begins in 1988 with the founding of BITZER Australia. In the following years, further locations are added around the world: Portugal, USA, Brazil, South Africa, China, etc.
Production site in Schkeuditz near Leipzig, Germany, is established as a competence center for reciprocating compressors
The acquisition of the Schkeuditz location near Leipzig, Germany, follows in 1991, and its expansion into the competence center for reciprocating compressors begins.
EuroScroll scroll compressors
With the development of the EuroScroll scroll compressors in 1996, we become the only company to offer all three primary compressor technologies: reciprocating, screw, and scroll compressors.
THE SCHAUFLER FOUNDATION ensures the future independence of BITZER as an autonomous company
In 2005, THE SCHAUFLER FOUNDATION is established. The foundation is the sole shareholder of BITZER SE. This ensures the independence and continuity of the company.
Global GREEN POINT service network with 54 locations worldwide
In 2006, our GREEN POINT service network is established. With our GREEN POINT network, we are able to provide a comprehensive service – 54 locations worldwide.
Further development of the ECOLINE series with the new CRII (VARISTEP) capacity control
In 2013, our ECOLINE reciprocating compressors feature the new CR II (VARISTEP) capacity control system, offering greater energy efficiency and a wider application range.
Since 2015
A Firm Eye on the Future
After the death of Senator h. c. Peter Schaufler in 2015, Christiane Schaufler-Münch becomes Chairwoman of the BITZER SE Supervisory Board and Chairwoman of THE SCHAUFLER FOUNDATION Board of Trustees.
After the death of Senator h. c. Peter Schaufler, the responsibilities within the management remain unchanged
“For me, BITZER is more than a company – it is like a family. Our strength comes from the ideas, commitment, and trust of our employees. Every day, they dedicate themselves to serving our customers around the world and enable us to grow and develop together.”
Inauguration of the SCHAUFLER Academy as an international training center in Rottenburg-Ergenzingen, Germany

Acquisition of ElectraTherm
We acquire ElectraTherm in 2017. This marks our entry into the market for the generation of electricity from waste heat. ElectraTherm uses ORC (ORC = Organic Rankine Cycle) technology to convert waste heat to electricity.
Acquisition of VaCom
VaCom has been part of BITZER since 2018. The California-based company focuses on development, analysis, consulting, and performance and energy monitoring for industrial refrigeration control systems.
New headquarters in Sindelfingen. Joint venture with the German automation expert Wurm
We move into our new company headquarters at Peter-Schaufler-Platz 1 in Sindelfingen in 2019. The building is a sign of our continued commitment to our base. We sign a joint venture agreement with German automation expert Wurm. We are now the majority shareholder of the newly established Wurm Holding GmbH.
