In 2022, the European Union (EU) announced that all refrigeration products made in the EU are required to have a Global Warming Potential (GWP) of less than 150. Soon after, the United States, Japan, and many other countries also established Fluorinated Gases (F-gases) Regulations to control the types of refrigerants used and promote refrigerating equipment that can reduce F-gases emissions.

Recently, ANKO has introduced many low GWP Food Machines that use “R1234ze” HFO-based refrigerant to replace “R134a”. These machines were tested and proved to have only 1/10 the GWP compared to the original models as well as comply with the EU and US F-gas standards.

The biggest challenge many machine manufacturers face when introducing new eco-friendly models using “R1234ze” refrigerant to replace “R134a” is the cooling effect does not compare with older models that use “R134a”. ANKO invested in the research and development to improve these new machines’ mechanical design. Finally, ANKO’s new machine models were tested using “R1234ze” eco-friendly refrigerants and they achieved cooling effects equivalent to older equipment using “R134a”. Since 2022, ANKO has upgraded all our appliances with an eco-friendly design that uses “R1234ze” for cooling.
