The CHEMOURS MO99_25LB is a 25-pound cylinder of MO99 refrigerant, a drop-in replacement blend engineered for air conditioning and refrigeration systems that currently operate on R-22. MO99 is formulated to work with existing alkylbenzene (AB), mineral oil (MO), and polyol ester (POE) lubricants, which eliminates the need for a complete oil flush during retrofit. It operates at suction pressures approximately 3 PSI higher and discharge pressures approximately 5 PSI higher than R-22, minimizing the need for expansion valve or line set modifications. Licensed HVAC technicians working on R-22 retrofit applications will find this cylinder sized for mid-to-large service jobs.
MO99_25LB is suited for residential and light commercial air conditioning and refrigeration retrofit applications where R-22 systems remain in service. The blend is designed to reduce overall retrofit costs compared to HFC or POE-only conversion paths. Because it is compatible with existing lubricants already present in the system, oil changes are not required in most retrofit scenarios, reducing labor time and minimizing system downtime. It also reduces the need for control set point adjustments after the retrofit, which lowers the likelihood of follow-up service calls.
Designed for use in R-22 air conditioning and refrigeration systems. Compatible with alkylbenzene (AB), mineral oil (MO), and polyol ester (POE) lubricants already present in existing systems.
Recovery and handling of refrigerants must be performed by an EPA Section 608 certified technician using certified recovery equipment. Always recover remaining R-22 charge before introducing MO99 into the system. Verify system pressures against manufacturer operating specifications after recharge. Do not mix refrigerant blends or top off an unknown refrigerant mixture without proper analysis.
