Product Regulations Card

New store installations with refrigerated systems for California beginning 1/1/2022 must not exceed 50 lbs of charge and use a refrigerant below 2,200 GWP. Systems greater than 50 lbs charge require refrigerants below 150 GWP. Existing store compliance for CA requires a reduced weighted average GWP of refrigerants used to less than 1,400 GWP for the fleet by 2030 or a 55% reduction of overall GHGP (charge not relevant).
