After serving for 18 years as the internet’s leading marketplace for CO2 (R744) cooling and heating technologies and trusted source for industry news, R744.com is shutting down, with the website’s marketplace and news moving to the brand new NaturalRefrigerants.com.

“When we launched R744.com 18 years ago, never in my wildest dreams would I have thought that the website would still be around and still be so relevant, today,” said Marc Chasserot, Founder and CEO of ATMOsphere, the publisher of R744.com and NaturalRefrigerants.com.

The new NaturalRefrigerants.com is a one-stop shop for natural refrigerant news and products. It consolidates ATMOsphere’s three previous websites (R744.com, Hydrocarbons21.com and Ammonia21.com) into a single platform showcasing the latest in sustainable HVAC&R technologies.

Unlike R744.com, which focused strictly on cooling and heating with CO2, NaturalRefrigerants.com will cover a broad spectrum of natural refrigerants, including CO2 and ammonia (R717), hydrocarbons like propane (R290) and isobutane (R600a), water (R718) and air (R729).

“By showcasing all natural refrigerants on one site, we can clearly show the full range of what they can offer the HVAC&R sector,” said Chasserot. “Each refrigerant has its strengths, and, between them, all applications are covered.”

R744.com will continue to function as an archive of past news stories, but the site will soon be sunset, with all links to past content redirecting to NaturalRefrigerants.com. Readers are encouraged to visit the new site and subscribe to the NaturalRefrigerants.com newsletter to continue to stay up-to-date on the latest industry news and innovations.
