Fluoro Refrigerant Gas

R-407C is a blend refrigerant developed as a substitute for HCFC-22. It is a mixture of HFC-32, HFC-125, and HFC-134a, and is a zeotropic refrigerant. It requires liquid filling to prevent change in composition. Its level of pressure is approximately the same as that of HCFC-22. It is highly compatible with ester oil and ether oil (It is not compatible with mineral oils like naphthenic oil etc. which is normally used with HCFC-22). Its moisture solubility is approximately the same level as that of HCFC-22.

R404A (HP62) has been the long-standing HFC replacement for R-502 and R-22 in refrigeration applications. HFC-404A is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in certain end use applications in the U.S. market. There are no U.S. regulations currently impacting the HFC service market. Refer to the Summary of U.S. EPA SNAP Regulations Pertaining to Refrigerants.

Lubricant Recommendation
POE

• Non-ozone depleting refrigerant, near-azeotropic blend.
• Developed for air conditioning as well as some medium temperature refrigeration applications.

• Residential and commercial air conditioning systems.
• Small chillers.
• Heat pumps.
• Dehumidifiers.
• Medium temperature commercial refrigeration.

Performance:

• Fluoro 410A has a high cooling capacity, thus leading to good performance with low refrigerant charge. Fluoro 410A provide the best energy efficiency for air conditioning.

Lubrication:

• Polyolester (POE) lubricant must be used with Fluoro 410A to ensure complete miscibility between oil and refrigerant. Care must be taken when handling POE lubricants because they are hygroscopic, which means that they can readily absorb moisture from the air. High levels of moisture in the system can lead to oil degradation and system failure.

Charging:

• Due to the near-azeotropic nature of Fluoro 410A, it is better to charge it as liquid to prevent fractionation (changes in the designed refrigerant composition) but it can also be charged as gas. In situations where vapor would normally be charged into a system, a valve should be installed in the charging line to flash liquid from the cylinder into vapor. Fluoro 410a requires the use of manifold gauge sets, recovery machines and cylinders specifically designed and rated for its higher pressures.

Deliveries:

• Fluoro 410A can be delivered in various packaging
• Bulk ISO container(16 tons) or ton-tank(650kg).
• Disposable cylinders 11.3 kg each (for exports only).
• Cylinders 45kg & 8kg.

R-410A is a blend refrigerant developed as a substitute for HCFC-22. It is a mixture of HFC-32 and HFC-125, and is a pseudo-azeotropic refrigerant. It requires liquid filling to prevent change in composition. Its level of pressure is approximately 1.6 times higher than that of HCFC-22, achieving excellent heatpump performance. It is highly compatible with ester oil and ether oil (It is not compatible with mineral oils like naphthenic oil etc. which is normally used with HCFC-22). Its moisture solubility is slightly higher than that of HCFC-22.
