New range boasts
higher compressor
efficiency
GEA BOCK WILL present a new generation of innovative CO2 and HC compressors for natural refrigerants for the very first time at EuroShop 2020 in Düsseldorf last month.
GEA Bock product manager for natural refrigerants, Manuel Fröschle, said the new subcritical and transcritical CO2 compres- sor series offer clever solutions for refrigeration systems especially in the application of supermarkets and distribution centres.
Describing the series as reliable and powerful, he said opera- tors benefit from improved process efficiency with minimized energy costs and a wide range of applications - also in combina- tion with heat recovery and air conditioning.
The theme for the world premiere is the Clever Art of Cooling. Fröschle said the HGX44e CO2 series, which is designed for in- dustrial low temperature applications, offers at least six per cent higher compressor efficiency compared to other compressors on the market.
"This allows operating costs in hypermarkets and distribution centers to be significantly reduced. And all this with the highest reliability during operation thanks to our proven GEA Bock CO2 compressor design," he said.
GEA Bock is also expanding its portfolio for transcritical ap- plications in the lower capacity range with the new HGX24 CO2 (L)T CO2 compressor series. With cooling capacities from 9 to 21 kW in medium temperature, the compressor is specially de- signed for system applications in supermarkets with smaller ca- pacities. "Thanks to the CO2-specific design, the compact com- pressors guarantee high flexibility in application through a wide frequency range with minimum partial load control and maxi- mum operational reliability," Fröschle said.
The company’s complete range of commercial HC reciprocat- ing compressors for hydrocarbon-based natural refrigerants such as propane and propylene will also be on show at EuroShop.

2020 WILL BE a defining year for the built environment, marking the dawn of a decade of action in which the in- dustry will be transformed by the Unit- ed Nation’s 2030 agenda for sustainable development.
Central to this is the Intergovern- mental Panel on Climate Change (IPCC) Special Report calling for all new buildings to be net zero within the next 10 years, and all existing build- ings by 2050 at the very latest.
Multi-disciplinary engineering con- sultancy, Cundall, has named 2020 the ‘Year of Net Zero’, announcing its reso- lution to collaborate with industry bodies to change the built environ- ment’s approach to net zero globally. Cundall is working alongside the Green Building Council of Australia (GBCA), Royal Institute of British Ar- chitects (RIBA), Hong Kong’s Con- struction Industry Council (CIC) and the Chartered Institution of Building Services Engineers (CIBSE) to help unify the industry and define targets, strategies and transition plans for achieving net zero carbon in both new and existing buildings.
David Clark, sustainability partner at Cundall, said in the last 12 months, there has been a significant shift in Australia in the level of urgency and willingness of industry to become zero carbon by 2030.

“We need to make this the norm, and push government policy to catch up so that everyone has to do it,” he said.
“Achieving zero carbon is a global challenge that requires strong tech- nical solutions and engineers will play a key role in delivering these. Cundall is dedicated to helping the industry and government meet the challenge.” Cundall managing part- ner, Tomás Neeson, said the compa- ny is under no illusions that achiev- ing its ambitious carbon goals would be straight forward.
“Net zero is a complex issue that needs the type of technical solution that we, as engineers, are well-placed to provide, and it is through the pro- cess of continuously learning from our project experience, developing our ap- proach and adjusting our methods that we can succeed,” he said.
