New NASRC Factsheet: Propane (R-290) Charge Limit

Overview: Propane (R-290) is a safe, climate-friendly refrigerant with tremendous potential to reduce greenhouse gas emissions from supermarket refrigeration.

Last year, the UL safety standard (60335-2-89) was updated to incorporate higher allowable charge sizes of propane. The goal of this factsheet is to accelerate updates to remaining codes and standards.

Topics Covered:

• Propane as a safe, cost-effective, and climate-friendly refrigerant

• Propane applications in supermarkets

• Approved UL safety standard that allows higher propane charge limits

• The latest status on the process to update remaining codes and standards
