Leading Supplier of High-Purity R507 Refrigerant Gas in UAE

R507 refrigerant remains a cornerstone of low-temperature commercial and industrial refrigeration across the UAE, specifically designed for applications where reliable, consistent cooling performance is critical. As an azeotropic HFC blend (composed of R125 and R143a), R507 is celebrated for its excellent thermodynamic properties, often outperforming the similarly applied R404A in systems requiring lower evaporator temperatures and a zero temperature glide. This characteristic is vital for cold storage warehouses, supermarket freezer units, blast freezers, and refrigerated transport vehicles operating under the high ambient temperatures of Dubai and the Northern Emirates.

Al Waleed A/C Spare Parts Dubai is the Leading Supplier of high-purity R507 refrigerant gas in the UAE, providing certified product in various packaging formats, from standard disposable cylinders to bulk Ton Tanks for large industrial consumers. We ensure continuous, compliant supply for the service and maintenance of existing low and medium-temperature refrigeration infrastructure.

Technical Performance and Application Focus

R507 is technically superior in many critical aspects of commercial refrigeration, making it the preferred choice for specific, high-demand installations:

• Azeotropic Blend: Unlike R404A (a non-azeotropic blend), R507 behaves essentially as a single component. This is a significant advantage in refrigeration systems because it means the blend composition does not change significantly if a leak occurs, simplifying the process of topping up the system without compromising performance.

• Low-Temperature Suitability: R507 is a highly effective, non-flammable (ASHRAE A1 safety rating) replacement for the phased-out R502, offering comparable capacity and pressure characteristics suitable for evaporator temperatures down to -40 degrees C and lower.

• System Efficiency: In a direct comparison with R404A, R507 typically demonstrates a slightly better Coefficient of Performance (COP) and cooling capacity, translating directly into reduced power consumption and lower operational expenses—a major cost consideration for energy-intensive cold storage facilities in the UAE.

• Applications in the UAE:

  • Commercial Cold Storage: Large freezer rooms and chillers used in the food and beverage industry.

  • Supermarket Freezers: Display cabinets and condensing units requiring stable low temperatures.

  • Transport Refrigeration: Essential for maintaining the cold chain in trailers and containers moving temperature-sensitive goods across the Gulf region.

Navigating R507 and High-GWP Regulations

It is critical for all stakeholders in the UAE to understand the regulatory context of R507. With a high Global Warming Potential (GWP) of approximately 3985, R507, like R404A, is subject to global HFC phase-down initiatives (such as the Kigali Amendment).

• Current Status: R507 remains essential for the continued service and maintenance of the vast existing inventory of refrigeration equipment installed before the phase-down began. While new equipment installation is increasingly restricted toward lower GWP alternatives (like R448A or R449A), reclaimed and virgin R507 is still required to service existing systems effectively.

• Strategic Planning: Al Waleed A/C Spare Parts Dubai offers consultation to help facility managers and contractors plan for the long-term, providing access to R507 while also stocking a comprehensive range of low-GWP refrigerants for eventual system retrofitting or replacement.

Technical FAQ for R507 Refrigerant Gas

Q: What is the Global Warming Potential (GWP) of R507 refrigerant?

A: The GWP of R507 refrigerant is approximately 3985 (based on IPCC AR5). This high value places it within the category of refrigerants being phased down globally, driving the industry toward lower GWP alternatives.

Q: Which refrigeration oil must be used with R507 refrigerant?

A: R507 is an HFC refrigerant and requires a synthetic POE (Polyolester) oil for proper lubrication. Unlike older refrigerants, it is not miscible with mineral oils or alkylbenzene oils. Using the wrong oil will lead to lubrication failure and compressor burnout.

Q: Can I use R507 to top-up an R404A system?

A: While R507 and R404A have very similar operating pressures, using R507 to top-up an R404A system is strongly discouraged and not recommended by manufacturers. This is because R507 is a pure azeotrope while R404A is a near-azeotrope, and mixing them can lead to an unpredictable composition, altering the system’s performance and pressure characteristics.

Q: Is R507 a suitable replacement for R22 or R502 in existing commercial systems?

A: R507 is considered an excellent long-term replacement for R502 in low-temperature systems due to its performance match. However, replacing R22 with R507 requires significant system changes, including the compressor and expansion device, and, critically, switching the system lubrication from mineral oil to POE oil.

Q: What are the container sizes available for R507 bulk purchase in the UAE?

A: We supply R507 in standard 11.3 kg (25 lb) disposable cylinders for service work, as well as in refillable containers ranging up to 60 kg, 950 kg Ton Tanks, and ISO Tankers (20,000 kg) for industrial consumers and large wholesalers.

Q: Why is R507 still required if it has a high GWP?

A: R507 is still required to service the existing installed base of commercial refrigeration equipment that was designed specifically for it. As the equipment life span is often 10 to 15 years, a service supply must be available until these older systems are retired or successfully retrofitted.

Q: What is the primary technical advantage of R507 over R404A?

A: The primary advantage is R507’s azeotropic nature. This means it exhibits virtually no temperature glide and its composition remains stable after a minor leak, simplifying field charging and ensuring consistent evaporator performance—crucial for sensitive food preservation.

Q: How must R507 refrigerant be charged into a system?

A: Although R507 is an azeotropic blend, it is a best practice, consistent with all modern refrigerant blends, to charge the system with the liquid phase of the refrigerant. This ensures the correct blend ratio of R125 and R143a enters the system.

Q: What is the boiling point of R507 at 1 atmosphere?

A: The normal boiling point of R507 at standard atmospheric pressure (1 atm) is approximately -47.1 degrees C (-52.8 degrees F), confirming its suitability for low-temperature freezing applications.

Q: Does R507 gas have any Ozone Depletion Potential (ODP)?

A: No, R507 is a Hydrofluorocarbon (HFC) blend, and like all HFCs, it contains no chlorine, resulting in an Ozone Depletion Potential (ODP) of zero.
