Mayekawa, a leading Japanese manufacturer of natural refrigerant refrigeration equipment, exhibited the new fourth-generation model of its NewTon ammonia (R717)/CO2 (R744) industrial refrigeration unit.
The cold chain must be sustainable everywhere to be able to meet the Millennium’s targets indeed.
OEM Kysor Warren Epta US has announced that it expects to bring its new CO2 (R744)-based condensing unit to the U.S. market by the end of 2022, according to a recent presentation by the company’s Sustainability and New Technologies Manager, Ignacio Chaparro.
A new plant manufacturing the low GWP HFO refrigerant 1233zd has commenced production in Dahej, Gujarat.
Integrating a building glycol loop to a supermarket transcritical CO2 (R744) system in Canada yielded “superior” results, according to Phillip Walker, Arneg’s Director of Refrigeration Solutions, who spoke during the ATMOsphere America 2022 conference on June 7–8.
An inverter propane (R290) compressor can reduce the energy consumption of vending machines by up to 27% compared to a fixed-speed compressor, according to research conducted by Embraco, a Brazilian manufacturer and brand of Nidec Global Appliance.
Test installations of R290 self-contained refrigeration systems in walk-in coolers at two Subway restaurants in Connecticut are said to have shown average energy savings of 50%.
The first hypermarket opened by French multinational retailer Carrefour in Cameroon is also the first to feature CO2 refrigeration.
Konvekta, a German manufacturer of CO2 (R744) heat pump systems for commercial vehicles, has developed a new software module – “Additional Energy Storage (AES) Mode” – that eliminates the need for an electric heater in electric buses, reducing both costs and energy consumption.
Austrian manufacturer AHT, part of Daikin, highlighted its propane (R290)-based cabinets and Active Monitoring System (AMS) as part of World Refrigeration Day, celebrated yesterday (June 26) under the theme “Cooling Matters.”
Hillphoenix announced the launch of R290 self-contained display cases, part of the company’s Second Nature® Natural product line. R290 cases are the newest addition to Hillphoenix’s expansive natural refrigerant portfolio and provide customers with a plug-and-play, flexible and compliant solution for their retail operations.
Trane®, global provider of indoor comfort solutions and services and a brand of Trane Technologies, announced today it is expanding its Sintesis™ Balance CMAF portfolio of multi-pipe units for simultaneous cooling and heating. The new models are now available with R-454B refrigerant in capacities ranging from 150 to 1,400 kilowatts (kW). The units deliver better cooling and heating efficiencies, improved operating maps and lower environmental impact compared to equivalent models with R-410A.

Manufacturer trial of new technologies designed to run on CO2 refrigerant have concluded that efficiency improvements are possible across various types of climate.
Cimco Refrigeration, a Toronto-based industrial refrigeration contractor, has reduced energy consumption at a Quebec-based meat-processing plant operated by Viandes Paquette by 2.5 million kWh annually with a low-charge ammonia/NH3 (R717) system. By reclaiming excess heat from the ammonia system, Cimco removed the need for any boilers at the plant.
U.S.-based supermarket chain Hannaford has equipped the entire frozen section of its new store in Brunswick, Maine, with propane (R290) self-contained cases, according to a recent presentation by Harrison Horning, Director of Maintenance, Retail Business Services – Hannaford and Stop & Shop, part of Ahold Delhaize.
German manufacturer Gea Heating & Refrigeration Technologies is expanding its ammonia product portfolio, adding two screw CompaX compressors and a brand-new Grasso X semi-hermetic screw compressor package.
We are all aware of the F-Gas legislation and the drive to low GWP refrigerants but this is only a small part of the overall solution to reduce climate changing emissions. Choosing a low GWP refrigerant does not guarantee a better energy efficiency and in some cases, it may even lead to an increase in the lifetime total emissions from the system if a lower efficiency option is selected. As well as refrigerant choice, there are other actions that can be taken to maintain or improve energy efficiency, reduce total emissions and in most cases they will even pay for themselves over the lifetime of the equipment.
Supermarket giant releases findings from store trial looking at energy efficiency impacts of switching from older CO2 solution to a lower flammability A2L system.
The F-gas regulation is continuously progressing with two new bans having come into effect from 1st January 2022 but most of the implications of the legislation are still hidden by the apparent abundant supply of higher GWP refrigerants.
