Refrigerant Buying Guide
Choose refrigerant by equipment compatibility first—then confirm application operating temperatures, cylinder net weights, purchasing requirements, and regional dispatch options.
Always inspect the equipment nameplate and OEM documentation. Verify the approved refrigerant chemical designation before placing an order.
Evaluate ASHRAE safety groups (A1 vs A2L) and target operating temperatures across residential HVAC, commercial cooling, or cold storage.
Confirm cylinder net weight (20 lb, 22 lb, 25 lb, 30 lb), Hazmat ground delivery guidelines, or full-pallet freight tiers (50+ cylinders).
Key Decision Criteria for HVAC Contractors
1. Identify the Exact Refrigerant Specified by OEM
Check the system service manual and data plate. Never substitute refrigerants based solely on marketing claims or similar pressure profiles without written manufacturer authorization.
2. Understand Flammability & Safety Groups (A1 vs A2L)
Next-generation refrigerants like R-454B and R-32 are classified as ASHRAE A2L lower-flammability refrigerants. They feature Left-Hand (LH) reverse thread valves and require spark-proof tools and recovery machines.
3. Select Factory-Sealed Cylinder Net Weight
KOOLIN provides factory-sealed cylinders engineered to precise industrial standards: R-454B (22 lb), R-32 (20 lb), R-410A (30 lb), R-407C (25 lb), R-404A (30 lb), and R-134a (30 lb).
