Principal Strategic Supplier of MAKSAL Copper Coils and Tubes Wholesale in UAE
The foundational requirement for a high-performing and safe Air Conditioning and Refrigeration (ACR) system in the UAE is the integrity of its copper line sets. Under the extreme ambient temperatures and continuous high-load operation prevalent across the Emirates, every component—especially the refrigerant piping—must be engineered to the highest international standards. MAKSAL Copper Coils and Tubes, manufactured in South Africa, provide the proven quality, precise specifications, and robust wall thickness required to ensure long-term durability and safety for commercial and residential installations.
Al Waleed A/C Spare Parts Dubai is the Principal Strategic Supplier of MAKSAL Copper Coils wholesale, offering a critical inventory that adheres strictly to the ASTM B280 Standard for Seamless Copper Tube. We provide both Standard and Economical grades, allowing contractors and project managers in Dubai and the Northern Emirates to match product specification directly to the system’s pressure demands and budget.
Technical Grade Analysis: Standard vs. Economical
MAKSAL coils are supplied as Soft Annealed Coils (ACR Grade), meaning they are internally cleaned, dehydrated, and pliable for easy bending during installation. The core difference between the grades lies in the Wall Thickness (WT), which directly impacts the Safe Working Pressure (SWP) and suitability for modern refrigerants like R410A.
| Coil Size (Inches OD) | Grade | Wall Thickness (WT) | Mass Per Meter (Approx.) | Critical Insight for UAE |
| 5/8 inch (15.88 mm) | Standard (B280) | 0.035 inch (0.89 mm) | 0.374 kg/m | Recommended for high-side R410A lines due to superior pressure rating. |
| 5/8 inch (15.88 mm) | Economical | 0.028 inch (0.71 mm) | 0.3016 kg/m | Suitable for low-pressure (suction) lines or R22 systems, offers cost savings. |
| 1/4 inch (6.35 mm) | Standard (B280) | 0.030 inch (0.76 mm) | 0.119 kg/m | Essential for small liquid lines under R410A pressure. |
The decision between Standard and Economical grade must prioritize system safety. For new R410A system installations, which operate at pressures up to 400 psi, the Standard grade coils with thicker walls offer a vital safety margin and enhanced resistance to fatigue and vibration, ensuring compliance with local engineering codes.
Usage and Application in UAE Projects
MAKSAL copper coils are the essential material for various critical applications within the UAE construction and maintenance sectors:
-
Line Sets for Modern AC: Used extensively for connecting indoor and outdoor units of split, multi-split, and Variable Refrigerant Flow (VRF) systems, particularly for the accurate sizing required for high-tonnage units (up to 1 1/8 inch OD).
-
Commercial Refrigeration: The larger diameter coils (7/8 inch and 1 1/8 inch) are crucial for constructing complex cold storage rooms, freezer systems, and medium-temperature chillers in the food supply chain and industrial facilities.
-
System Integrity: The ACR Grade cleanliness—guaranteed by the strict ASTM B280 manufacturing—ensures that the interior of the tube is free of moisture and contaminants. This prevents harmful chemical reactions with refrigerant oil (especially POE oil) and guards against the formation of sludge and clogs in Thermal Expansion Valves (TXVs).

Technical FAQ for MAKSAL Copper Coils and Tubes
Q: What is the primary safety risk associated with using Economical grade copper coil in an R410A system?
A: The primary safety risk is the reduced Wall Thickness (WT) of the Economical grade (e.g., 0.028 inch for 5/8 inch). This thinner wall may not provide the necessary safety margin to reliably contain the consistently high operating pressures of R410A (which can exceed 400 psi), increasing the risk of bursting, fatigue failure, or slow leakage.
Q: What does the term “Soft Annealed” mean in the context of MAKSAL Copper Coils?
A: Soft Annealed refers to the temper of the copper. It means the coils have been heat-treated to make them fully pliable and soft. This is essential because it allows the technician to easily bend the tubing by hand or with simple bending tools, reducing the need for hard fittings and minimizing potential leak points.
Q: What is the significance of the “Mass Per Meter” specification (e.g., 0.673 kg/m)?
A: The Mass Per Meter (kg/m) is a direct indicator of the material content and wall thickness. It confirms that the coil meets its published specifications. Bulk buyers and quality inspectors use this metric to verify the product’s quality, ensuring they receive the full material value and thickness expected for the Standard grade.
Q: How do I ensure the integrity of the copper tubing joints during installation in Dubai?
A: Integrity is ensured by two mandatory steps: (1) Flaring or Brazing: Using correct flaring tools or high-silver content brazing material. (2) Nitrogen Purge: Pumping nitrogen gas through the lines during brazing to prevent internal copper oxide (scale) formation, which would contaminate the refrigerant system.
Q: What is the standard international specification that MAKSAL Copper Coils adhere to?
A: MAKSAL Copper Coils adhere to the ASTM B280 Standard, which specifically governs seamless copper tubing intended for use in the field service of air conditioning and refrigeration systems.
Q: Can MAKSAL soft copper coils be used for chilled water piping in commercial buildings?
A: While technically possible, for large-scale chilled water distribution (non-refrigerant) systems, hard (straight) copper tubes (often ASTM B88 Type L or M) are typically preferred for structural rigidity, as soft coils are difficult to manage over long, straight runs.
Q: What is the recommended cleaning procedure for MAKSAL coils before final installation?
A: Since the coils are supplied as ACR Grade, they are already internally cleaned and sealed. The only recommended procedure is to ensure the ends remain sealed until the moment of connection and to purge with nitrogen during the brazing process to maintain internal cleanliness.
Q: Does Al Waleed A/C Spare Parts Dubai stock the fittings required for MAKSAL coils?
A: Yes, we stock a complete range of compatible copper fittings, couplings, reducers, and high-silver brazing alloys necessary to complete line set installations using MAKSAL coils, ensuring a single procurement source.
Q: What packaging sizes are most common for bulk purchasing of MAKSAL coils?
A: Bulk purchasing typically involves cartons containing multiple coils (e.g., 4, 5, or 10 coils per carton), depending on the diameter. This bulk packaging is optimized for secure stacking and containerized shipping to large construction sites.
Q: Why is the origin (“Made in South Africa”) important to UAE contractors?
A: The “Made in South Africa” origin, combined with the ASTM certification, provides assurance of manufacturing quality and consistency. Buyers trust these sources for reliable material integrity, which is essential to prevent costly call-backs and premature system failure.
