National committees on the International Electrotechnical Commission (IEC) voted 75% “yes” to increase the charge limit of A3 (flammable) refrigerants like propane in commercial refrigeration equipment to 500g from 150g. It sets the stage for a potential final vote phase (FDIS) that might happen in the end of this year.
On July 13th national committees on the International Electrotechnical Commission (IEC) voted in favor to the increase from 150g to 500g of A3 (flammable) refrigerants in commercial refrigeration equipment. This important milestone sets the stage for a potential final vote phase (FDIS) that might happen in the end of this year.
As an innovation-focused multinational and one of the world’s largest manufacturers of hermetic compressors for refrigeration, Embraco has been using natural refrigerants for more than 20 years in its portfolio of compressors for commercial segment and considers this approval as an important step for the market:
“Embraco already offers a full range of high efficiency compressors for light commercial applications and faces this decision as a reinforcement that the company is on the right way and also as a positive push for the sector development in this sense”, Marek Zgliczynski, Director of Research and Development at Embraco North America.
Besides establishing a guideline, this vote reinforces a point widely defended by specialists: ”It is possible to mitigate flammability risk of the refrigerants. The entire appliance using it has to be designed to prevent creation of risky concentrations in case of leak. This limit increase will allow manufacturers and end users to use the system in its full potential”, complement Marek Zgliczynski.
Embraco is looking forward for the next steps that will determine whether the higher charge limit is enacted as an international standard. Meanwhile, the company continues to consider natural refrigerants – especially hydrocarbons – as the ideal solution for the future of refrigeration by sustainably aligning economic and environmental needs.
