California Air Resources Board (CARB) Final Regulation Order – Part 2

In part two of our summary of The CARB Final Regulation Order, we will be reviewing the latest information regarding the use of refrigerants in equipment moving forward in California.

Hudson is excited to hear about OEMs starting to use lower GWP refrigerants, as well as reclaimed refrigerants in their equipment. These lower GWP refrigerants have a positive impact on the circular economy and can help combat the negative affects high GWP refrigerants have on global warming potential.

Hudson Technologies is looking forward to assisting with this transition, to help protect the environment!
