‘The Future is Natural,’ Says TEKO’s Managing Director
Andreas Meier described the German OEM’s transition from f-gas to mostly CO2 systems at the ATMO World Summit.

Inquiries have shot up since 2017 for industrial CO2 systems above 250kW and above 500kW.
This is the second store worldwide with plans to employ Energy Recovery’s device, following a Vallarta supermarket in California.
Air-to-water models, which are particularly popular in Denmark, account for 75% of Fenagy’s heat pump projects in the last 12 months.
But European Environmental Bureau contends that the proposal falls short by allowing f-gases in applications where natural refrigerants are available.
The move is part of a DKR 2.5 billion (US$366 million) investment in energy efficiency and climate-friendly technologies, which also includes solar panels and heat pumps.
The ‘smart’ CO2 supermarket will be fully functioning and run by Brugsen, Denmark’s largest cooperative retailer.
The Annex 58 high-temperature heat pump project has reviewed systems supplying temperatures over 100°C and found refrigerants like CO2, water, hydrocarbons, helium and ammonia being used.
Customized system uses R290-chilled glycol to keep the CO2 in subcritical mode.
The system was developed at the Center for Energy Technology (ZET) at the University of Bayreuth
