Cairo Dust — Condenser Coil Killer

Cairo is one of the world’s dustiest major cities. Fine particulate matter — desert sand, vehicle emissions, construction debris — settles on outdoor condenser coils and bonds with moisture during humid periods, forming a hard scale that restricts airflow and retains corrosive compounds against the copper surface. Egyptian rooftop condensers clog and corrode 2–3 times faster than equivalent systems in Northern Europe or North America. Coil replacement becomes necessary long before the rest of the system is worn out.

Coastal Salt Corrosion — Alexandria & Canal Zone

Salt-laden air from the Mediterranean, the Red Sea and the Suez Canal accelerates electrochemical corrosion on both the copper tubes and the aluminium fins of condenser and evaporator coils. Buildings within 5km of the coast in Alexandria, Port Said, Suez, Ismailia and Hurghada experience coil corrosion rates that make coil replacement a regular maintenance event rather than an extraordinary repair.

Cold Room & Refrigeration Construction Boom

Egypt’s food export requirements, pharmaceutical cold chain expansion, and the growth of supermarket chains across the country are driving significant construction of new cold rooms, walk-in freezers and commercial refrigeration facilities. Each new cold room requires custom-built evaporator coils fabricated from copper tube. Egyptian refrigeration contractors building these systems order bare copper coil tube from Dubai in significant volumes.

Why Copper — Not Aluminium — for Egypt

Many modern split AC systems use aluminium coils. For Egypt’s market, copper remains the preferred material for coil replacement and custom coil fabrication because copper is field-brazeable — a skilled Egyptian refrigeration technician can repair a leaking copper coil on-site with a torch and brazing rod. Aluminium coil requires TIG or MIG welding with inert gas shielding — not practical in Egypt’s field service environment. Copper coil repair vs aluminium coil replacement is a significant cost difference in favour of copper.

Residential Split AC Condenser — 3/8″ & 1/2″

Standard residential split AC condenser coils (1-ton to 2.5-ton) use 3/8″ or 1/2″ copper tube in serpentine rows with pressed aluminium fins. NWM STD or REG grade is the specification for R410A condensers — R410A operates at higher pressures than R22 and requires adequate wall thickness throughout the refrigerant circuit including the condenser coil tube itself.

Commercial & Cassette Condenser — 5/8″ & 3/4″

Larger commercial split AC, cassette units and light VRF/VRV systems use 5/8″ or 3/4″ condenser coil tube. Egypt’s commercial building sector — offices, hotels, New Administrative Capital government buildings — is driving sustained demand for commercial-grade condenser coil replacement. REG grade NWM for all commercial R410A condenser coil applications.

Large Commercial & Industrial — 7/8″ & 1-1/8″

Large commercial condensers, water-cooled condensers and industrial refrigeration condensers use 7/8″ and 1-1/8″ diameter tube. The Maksal 1-1/8″ is the largest format available from Al Faisal — the only brand stocking this size in Egypt export. NWM 7/8″ in ECO and STD for mid-range commercial applications. Mueller Streamline® ACR tube for international-spec commercial condenser fabrication.

Water Condenser — LRC Series

Al Faisal also stocks the LRC Series water condenser — a pre-built shell-and-tube water condenser for commercial and industrial refrigeration systems where water cooling is used instead of air cooling. Water-cooled systems are common in Egypt’s large commercial buildings and industrial facilities where the rooftop ambient is too hot for air-cooled condenser performance.

Cold Room Evaporator Coils — Egypt’s Biggest Application

Egypt’s rapidly expanding cold room sector — food export facilities in the Delta, pharmaceutical cold stores in Cairo, seafood storage in Alexandria and Port Said, supermarket cold rooms across the country — generates strong demand for evaporator coil tube. Cold room evaporators are typically fabricated from 3/8″ or 1/2″ copper tube using R404A or R507A refrigerant. NWM REG grade at minimum — cold rooms operate continuously at maximum thermal load.

Split AC Evaporator Coil — Indoor Unit

Split AC indoor unit evaporator coils use 3/8″ copper tube in a fin-and-tube arrangement. Evaporator coil leaks in split AC are caused by formicary corrosion (from formic acid in construction materials — very common in Egyptian apartments) and refrigerant contamination from system burnout. Field replacement requires 3/8″ copper tube and brazing skill. NWM STD or REG for R410A systems.

Domestic Refrigerator Evaporator — 1/4″ & 5/16″

Domestic refrigerator evaporator coils use small-diameter copper tube — typically 1/4″ or 5/16″. Leaks develop from vibration fatigue at bends and from copper oxidation over time. Egyptian refrigerator repair workshops that replace domestic evaporator coils (rather than the whole refrigerator) need small-diameter ACR-grade copper tube and fine brazing skill. Mueller Refrigeration Service Tube (soft copper coil) is the standard for this application.

Commercial Display Case & Ice Machine Coils

Supermarket display case evaporator coils and commercial ice machine evaporator coils use 5/16″ to 3/8″ copper tube with close-fin-spacing aluminium fins for maximum surface area. Egypt’s growing modern retail sector — supermarkets expanding from Cairo into secondary cities — is driving steady demand for display case evaporator coil replacement. R134a (display cases) and R404A (frozen food sections).

Field-Brazeable — Repairable On-Site

Copper can be brazed in the field with a standard propane or MAPP torch and silver brazing rod. An Egyptian technician can repair a copper coil leak on-site without special equipment. Aluminium coil repair requires TIG/MIG welding with inert gas — not practical in field conditions. This makes copper dramatically more cost-effective for Egyptian repair and maintenance operations.

Twice the Heat Transfer Conductivity

Copper has approximately twice the thermal conductivity of aluminium — meaning the same tube size transfers more heat per unit area. In Egypt’s high-ambient-temperature conditions where heat rejection is critical, copper coil efficiency translates directly to reduced system head pressure and better compressor longevity.

High Pressure Integrity — R410A & R404A

Rated for modern refrigerants.

Properly specified copper tube (STD or REG grade) handles both R410A (high-pressure split AC) and R404A (commercial refrigeration) safely and reliably. NWM STD and REG grades are pressure-rated for these applications across all standard AC and refrigeration coil configurations.

Nitrogen Purging During Brazing — Mandatory

Critical installation step.

When brazing copper coil tube, always maintain a slow nitrogen flow through the tube interior. Without nitrogen purging, the heat of brazing oxidises the copper inner surface, creating copper oxide scale that circulates through the refrigerant system and damages the compressor. This step is non-negotiable for professional coil fabrication.

🚢 Sea Freight — Jebel Ali

Jebel Ali to Alexandria or Port Said. 7–10 days transit. Copper coil is general cargo — no dangerous goods classification. Best cost efficiency for bulk coil orders. Consolidate with compressors, refrigerant gas (Class 2 DG handled separately) and spare parts in one LCL shipment.

✈️ Air Freight — Dubai Airport

Dubai to Cairo International. 24–48 hours. Copper coil is general cargo — no DG restriction. Weight-based air freight rates make copper less cost-efficient to air freight than lighter components. Sea freight is strongly preferred for bulk coil orders. Air viable for small urgent coil sample orders.
