High pressure design for compact compressors
GEA BOCK HAS expanded its semi-hermetic CO2 compressor range with an offering for tran- scritical applications in the lower capacity range.
Cooling capacities from 5 to 26 kW and heating capacities from 10 to 48 kW offer flexible stationary and mobile use in applica- tions for supermarkets, commercial and small industrial refrigeration systems as well as for air conditioning and heat pumps in buses and trains.
With their CO2-specific pressure design of up to 150 bar (HP) and 100 bar (LP) and a fre- quency range of up to 70 Hz, the gas-cooled compressors achieve the highest EER/COP val- ues within their application spectrum – with up to five per cent higher efficiency in standard medium cooling compared to commercially available compressors in this segment. GEA BOCK product manager for natural refriger- ants, Manuel Fröschle, said the new transcriti- cal compressors have proven themselves in ex- tensive internal testing and in numerous field tests with customers.
“They come equipped with all the necessary features for use with the natural refrigerant R744 and they are available from February 2021,” he said.
“The advantages of the new range include significantly re- duced energy and operating costs combined with a long ser- vice life and low maintenance re- quirements.
“They are suitable for a wide range
of applications - from medium and low temperature applications to high-temperature heat pumps – with reliable and flexible part load, as well as excellent low-noise and low-vi- bration running comfort with a minimal oil carry over rate.”
The basis for this is a CO2-optimized driv- ing gear design combined with proven BOCK compressor technology. This includes, for ex- ample, the oil pump for a reliable lubrication system even under demanding conditions in-

cluding large permissible inclination angles of the compressors.
For special subcritical requirements in low temperature applications with high operating and standstill pressures, the semi-hermetic BOCK CO2 compressor program will offer the specifically designed low temperature cooling variant HGX24 CO2 LT (Low Temperature) with two motor versions from June 2021.
Supply chain decarbonisation
SCHNEIDER ELECTRIC LAST month an- nounced an enhanced global supply chain de- carbonisation service which is designed to help organisations address emissions contained in their value chains.
The announcement comes on the heels of the company’s new ambition to increase its own ef- forts to decarbonize its supply chain, commit- ting to reduce carbon emissions from the top 1000 suppliers’ operations 50 per cent by 2025.
For many companies, a majority of their carbon footprint rests in the supply and value chain.
For many companies, a majority of their carbon footprint rests in the supply and value chain.
CDP research, based on 2020 data from more than 8,000 companies, found supply chain emis- sions are more than 11 times higher on average than operational emissions. These volumes can be even larger in industry segments like retail, apparel, and services.
Schneider Electric’s offer, which is nested in- side the company’s broader Climate Change
Advisory Service, helps organisations tackle this staggering figure through a unique combi- nation of supplier engagement, measurement, strategy setting, and implementation via effi- ciency, renewable energy procurement, and carbon offsetting.
The offer builds on successful supply chain solutions already developed for clients includ- ing Walmart, Maple Leaf Foods and Takeda Pharmaceuticals.
Schneider Electric VP, Steve Wilhite, said the momentum on corporate climate action today is tremendous, driven in large part by in- creasing investor pressure for environmental, social and governance (ESG) risks transpar- ency and disclosure.
He said for a majority of companies, the next frontier beyond their own operations is the supply chain.
“The good news is that by engaging suppliers in decarbonization efforts, companies can not only respond to these pressures but also identi- fy cost savings, develop innovations, and in- crease the value of their supplier relationships,” Wilhite said.
Schneider Electric is aiming for a net zero sup- ply chain by 2050.
