World Refrigeration Day, celebrated every year on 26 June, pays tribute to refrigeration technology. This year’s motto is "Next Generation Cooling: The Future is in our hands."
Refrigeration, air conditioning, and heat pump technology is an industry of the future. It offers diverse career prospects with a variety of occupational profiles as well as innovative technologies.
Economically robust refrigeration
"The need for cooling will remain in demand despite global warming," says David Ziegler, certified Refrigeration System Engineer and Junior Application Engineer at BITZER. It’s why he continues to see his professional future in the economically robust refrigeration, air conditioning, and heat pump industry. At BITZER, he has carved out a career path that is also sought out by Generation Z: he pursues meaningful work – activities with a "purpose" that have a positive impact on society as a whole as well as the environment.
Issue that concerns all generations, regardless of their potential field of work in the company"
According to Ulrich Harm, Director of Human Resources at BITZER, the operating specialist in refrigeration, air conditioning, and heat pump technology, "Sustainability is increasingly a key topic in our job interview process. It’s an issue that concerns all generations, regardless of their potential field of work in the company. When we ask candidates why they want to work with us, a common response nowadays is that they see how committed BITZER is when it comes to sustainability and energy efficiency."
BITZER ethos
Green is not just the company’s corporate color; it is an integral component of the BITZER ethos: sustainability is at the core of the company’s work when developing and manufacturing products and implementing processes. Right from the outset of discussions surrounding the depletion of the ozone layer in the 1980s, BITZER has focused its efforts on developing compressors for natural refrigerants with low global warming potential. BITZER has been manufacturing compressors for naturally occurring refrigerants, such as propane (R290) since 1987, ammonia (R717) for even longer, and CO2 (R744) for more than 20 years.
What’s more, it has continued to optimize these refrigerants through the years. The newest large-scale ammonia screw compressors, for example, are the most efficient in their performance class. In addition, the company is always working on new, even more, efficient capacity controls of its products by increasingly developing and integrating electronics and software to further reduce the energy consumption of its refrigeration and air conditioning systems.
BITZER factory
BITZER also ensures efficient use of the resources needed to manufacture its products. Solar panels on the roof of the Rottenburg-Ergenzingen site, in Germany, generate an output of two megawatts. Together with a combined heat and power system and an in-house developed, produced and operated Organic Rankine Cycle (ORC) system, which generates power from waste heat, the site can supply over 60% of the electricity it requires itself.

If the newly acquired wind turbine – located near Rottenburg-Ergenzingen – is taken into account, the BITZER factory can produce over 65% of its own electricity in the future. A part of the electricity generated flows directly into the charging stations for electric vehicles.
Ulrich Harm: "There are many examples that prove we’ve been working on our climate-neutrality goals for several decades now. We continually optimize our products and processes and encourage our employees to walk this path with us – so that together we can do our part in upholding an industry that has its eyes firmly set on the future."
Early integration ensures long-term wins
Anyone deciding to take up a job in the refrigeration, air conditioning, and heat pump industry can make a significant contribution to doing business in a sustainable manner. The challenges facing the refrigeration and air conditioning sector are great and the professional prospects are plenty. To initiate contact with the "Next Generation Cooling" and to arouse the interest of young talent in its areas of expertise, BITZER has put several measures in place.
A key player in its recruitment efforts is the company’s own international training center, the SCHAUFLER Academy, through which BITZER maintains close relationships with institutes and vocational schools that train potential skilled workers. BITZER supports these schools with learning material and practical training courses.
Vocational training concept
All trainees receive a job offer after successfully completing their vocational training
BITZER has been training young people in various fields for many years now. Its current areas of specialization include industrial business manager (m/f/d), industrial mechanic (m/f/d), mechatronics engineer (m/f/d), metal technology specialist (m/f/d), information technology specialist (m/f/d), technical product designer (m/f/d), and warehouse logistics specialist (m/f/d). All trainees receive a job offer after successfully completing their vocational training. Many of them also join BITZER as trainees during the practical phase of their dual degree courses.
Introductory days, departmental rotations and projects, as well as seminars and excursions, help the next generation of potential employees familiarize themselves with the company and its culture. The possibility of an assignment abroad, campfire evenings and days when trainees can shadow managers in their daily business round off the vocational training concept at BITZER.
Schaufler Foundation
Internships, dissertations, and work placements provide additional opportunities to take a deep dive into the world of refrigeration, air conditioning, and heat pump technology at BITZER. The Schaufler Foundation, of which BITZER is a majority stakeholder, also promotes research opportunities in the industry through endowed professorships and international student exchange programs.
Carrying out smaller tasks and projects gave me a better insight into the workings of departments"
David Ziegler recalls his journey at the company: "I came across BITZER during my school days as part of an information day hosted by different universities. The HR department of BITZER was on-site to introduce their entry opportunities." David Ziegler then chose to pursue a dual degree course with practical phases in refrigeration system technology at BITZER. "During these practical phases, I got to know various departments, such as the technical development and sales departments. Carrying out smaller tasks and projects gave me a better insight into the workings of each of these departments. It helped me get a feel for how processes at BITZER are realized and how products are manufactured," reminisces David Ziegler.
He stayed on at BITZER following his studies and began his career path at the company with a special 18-month-long entry-level program for young engineers which enabled him to delve deeper into the world of BITZER. Having already completed his dual degree course at BITZER meant he was able to reduce the program duration to 12 months. A stint abroad as part of the program is a distinct advantage that BITZER, with its international operation across 75 locations in 40 countries, offers.
Sciences and refrigeration technology
David Ziegler is as enthusiastic about his work in the refrigeration, air conditioning, and heat pump industry as he was on his first day four years ago. It’s because BITZER is constantly growing and developing in the face of the challenges posed by climate change and increasing awareness of the environment.
"Not to mention, I find the industry 'cool' because it’s so omnipresent in all our lives," says David Ziegler. "A keen interest in the sciences and refrigeration technology is essential when starting out. For example, if you’re someone that wonders how fresh vegetables from South America end up on supermarket shelves in southern Germany or how ice rinks stay frozen during the summer, then the chances that you’re in a field where you feel at home and can grow professionally are very high," says David Zielger.
