At the beginning of this year BITZER Brazil built a fully functional, transcritical CO2 supermarket booster system in its training center and provides refrigeration and air-conditioning professional experts a hands-on experience. 

BITZER Brazil is one of the biggest developers of CO2 technology in South America, and since 2008 more than 1,000 technicians have been trained in CO2 technology at the BITZER Brazil Training Centre. The focus of the Training Center, which is the only one of its kind in the Americas, is to present new technologies and to introduce carbon dioxide as a refrigerant and promote its application in industrial and commercial refrigeration systems. During the CO2 training courses, safety issues, design features, installation, commissioning, servicing and maintenance procedures will be discussed in both practical and theoretical classes.

CO2 Trancritical System
The system is built as a booster system with gas bypass. The gas from the low pressure compressor is mixed with gas from the gas bypass as well as from the medium temperature evaporators. The gas that exits in the low temperature compressor is cooled and can then safely enter the high temperature compressor. The booster principle is used because it gives a safe oil return and good system efficiency. 

General information about the CO2 training course
The carbon dioxide course has been developed by BITZER Brazil’s experienced engineers and. the information about the use of CO2 in refrigeration systems was collected from many sources from around the world. The information has been put together into a five-module course that icnludes:
  • CO2 Fundamentals;
  • Systems Safety with CO2 Applications;
  • CO2 Refrigeration Systems;
  • CO2 Refrigeration System Components;
  • Commissioning, Servicing and Maintenance Procedures. 

The CO2 training courses are intended for students, technicians, engineers, designers, installers and for those interested for this subject as well. 
The course lasts 5 days with both theoretical classes and hands-on training; The training courses are provided in the Portuguese, Spanish and English versions.
For more information about the CO2 training courses please contact Mrs. Viviennne Thudichum, Marketing Department,
