Primary Uses & Applications

The r507 refrigerant is specifically designed for commercial refrigeration applications where CFC-502 was previously used. Its azeotropic nature ensures consistent performance.

Commercial Refrigeration

• Supermarket display cases

• Walk-in coolers and freezers

• Convenience store refrigeration

Industrial Cooling

• Cold storage warehouses

• Food processing and distribution

• Industrial process cooling systems

Retrofitting

• Direct replacement for CFC-502 systems

• Requires oil change to PAG and system modifications

Material Compatibility & Safety

Compatible Materials

Most common metals (copper, brass, steel) and plastics are suitable in dry systems. At high temperatures, use stainless steel or Inconel.

Materials to Avoid

Avoid alloys with >2% magnesium (certain aluminium alloys). Do not use natural rubber in hoses/gaskets. Reacts violently with alkali/alkaline earth metals (sodium, potassium).

Oil Compatibility

Compatible with Polyalkylene Glycol (PAG) oils. Mineral oil (MO) and Alkyl Benzene (AB) oils are not compatible and must be replaced during retrofitting.

Frequently Asked Questions about R507 Refrigerant

What is the main advantage of R507 refrigerant over other blends?

+

R507 refrigerant (R507A) offers several key advantages for commercial refrigeration:

Azeotropic Blend: Minimal temperature glide ensures consistent system performance and easier charging compared to zeotropic blends

Direct CFC-502 Replacement: Designed as a drop-in replacement with minimal system modifications (oil change required)

Energy Efficiency: Excellent thermodynamic properties for medium-temperature refrigeration applications

Application Note:

R507 is particularly suitable for supermarket refrigeration systems, cold storage, and industrial cooling where CFC-502 was previously used.

What oil should I use with R507 refrigerant in a retrofit application?

+

When retrofitting a system from CFC-502 to R507 refrigerant, proper oil selection is critical:

Recommended Oil

Polyalkylene Glycol (PAG) oil is the recommended lubricant for R507 refrigerant systems. It provides excellent solubility and lubrication properties.

Oil Change Procedure

Complete oil flush is required when converting from CFC-502. Residual mineral oil can cause poor oil return and system performance issues with R507.

⚠️ Important Retrofit Consideration

Always consult with a qualified technician before retrofitting. System components like seals, gaskets, and filter-driers may also need replacement when switching to R507 refrigerant.

What is the shelf life of R507 refrigerant, and how should I store it?

+

Proper storage extends the shelf life and maintains the quality of R507 refrigerant:

×

Shelf Life: Typically 5 years from production date when stored properly

×

Storage Temperature: Keep below 52°C (125°F), avoid temperature fluctuations

×

Orientation: Store cylinders upright with valve protection caps secured

×

Environment: Store in a cool, dry, well-ventilated area away from ignition sources

Storage Best Practice for R507 Refrigerant

Always check the production date on the cylinder before use. Store in a dedicated storage area with proper signage. Keep away from incompatible materials and heat sources.
