Bitzer recently held a two-day CO₂ course (transcritical) at its training centre in Rottenburg, Germany, which attracted considerable interest from the industry.

The course was designed to provide a better understanding of the basics and enhance knowledge; enable delegates to practise commissioning and troubleshooting in realistic exercises; and look at the trend towards eco-friendly refrigerants.

All of those who took part agreed that the role of CO₂ refrigerants will grow and felt it was important to keep abreast of the trend towards eco-friendly refrigerant. Participants considered CO₂ to be the ideal refrigerant, particularly when it comes to supermarket refrigeration systems (booster and cascade systems).

The speakers on the course shared both theoretical and practical basic knowledge on the use of the refrigerant CO₂. The practical section offers training in commissioning and troubleshooting in realistic exercises. The trainers also examined specific topics associated with Bitzer products and CO₂ applications in more depth.

The Bitzer Group has more than 15 years of experience in the development and manufacture of compressors for use with the refrigerant CO₂ for sub- and transcritical applications. CO₂ is establishing itself at different speeds in different parts of the world, with northern Europe, Australia and Switzerland leading the way. Bitzer began working with the technology early on and has launched and continuously further developed products for a variety of demands.

Bitzer recently celebrated the 100^th CO₂ training course held at its Rottenburg facility.
