Chemours Refrigerants

Freon™ refrigerants

The Freon™ brand has been trusted by the industry since the first fluorochemical refrigerants were introduced to the marketplace by our business over 85 years ago. Over this time, Freon™ has come to stand for the highest quality and performance across multiple applications within air conditioning and refrigeration.

As our business developed new HFC products they took on new tradenames, including Suva™ and ISCEON™. However, as we began to transition to Chemours, we recognized the value of the Freon™ brand and have since taken steps to amplify it. As a result, our full HFC portfolio will be represented by Freon™ going forward.

See the table below to determine which Freon™ refrigerant is right for your business.
