*See Extended Capacity Tables for ratings at a wide range of conditions per ARI standard 750.
**Use SZ charge for all R-448A/R-449A applications. Recommend oversizing the valve capacity by 50% for low temperature applications.
Features
• Stainless steel power element eliminates corrosion and
prevents valve failure
• Hermetic, leak-free construction
• Compact size allows installation in limited spaces
• Mass spectrometer tested to ensure less than 0.10 oz/year
external leakage rate
