WESTRON 1/4 Inch Copper Coil — Uzbekistan

6.35mm OD · Liquid Line · 15m Roll · Bare

The standard liquid line for all residential split AC systems up to 2 tons — the highest-volume copper coil size in Nigeria’s residential AC installation market. Every new split AC installation across Nigeria’s residential construction boom requires 1/4 inch liquid line copper. The WESTRON® 1/4 inch coil is Al Waleed’s most consistently ordered copper product for Nigeria, frequently shipped in the same sea freight consignment as WESTRON® R410a or R22 refrigerant cylinders — the refrigerant and the copper line set travelling together in one shipment.

Applications: Residential split AC liquid line · all brands and capacities up to 2T · small commercial AC liquid line

WESTRON 3/8 Inch Copper Coil — Uzbekistan

9.52mm OD · Suction Line (Small AC) · 15m Roll · Bare

The suction line for 0.75-ton residential split AC and a key size in domestic refrigerator and small commercial refrigeration repair work. Nigerian refrigerator repair technicians working on LG, Samsung, Haier, and Hisense domestic fridges regularly need 3/8 inch copper for evaporator coil replacement and refrigerant line repair — creating consistent demand alongside the AC installation segment. WESTRON® 3/8 inch coil consolidates well with WESTRON® R600a refrigerant in the same import order for dealers serving both the AC and fridge repair markets.

WESTRON 1/2 Inch Copper Coil — Uzbekistan

12.7mm OD · Suction Line (1–1.5T) · 15m Roll · Bare

The most-ordered WESTRON® copper coil size for Nigeria — the 1/2 inch suction line for 1-ton to 1.5-ton residential split AC, which together with the 1/4 inch liquid line accounts for the copper requirement on the vast majority of Nigeria’s residential AC installations. A Nigerian dealer who orders WESTRON® 1/4 inch and 1/2 inch copper together with their WESTRON® R410a and R22 refrigerant cylinders has a single-brand, single-supplier, single-shipment approach to stocking the core consumables of their AC installation and service business.

Applications: Residential split AC suction line 1T–1.5T · all brands · the highest-volume suction line size in Nigeria’s market

WESTRON 5/8 Inch Copper Coil — Uzbekistan

15.88mm OD · Suction Line (2–2.5T) · 15m Roll · Bare

The suction line size for 2-ton to 2.5-ton split AC — covering large living rooms, executive homes, bank branches, and commercial spaces across Nigeria. As Nigerian housing and commercial construction continues to grow in scale, 5/8 inch copper demand grows proportionally with the 2-ton AC segment. WESTRON® 5/8 inch coil is available from Al Waleed for Nigeria export alongside the smaller residential sizes — Nigerian dealers who stock the full WESTRON® copper range from 1/4 inch to 5/8 inch can serve the complete residential installation market from a single brand.

The 3/4 inch suction line for 3-ton and above split AC and commercial cassette systems — the HVAC range serving hotels, hospitals, bank headquarters, and office buildings across Nigeria. WESTRON® 3/4 inch coil extends the brand’s copper range into the commercial AC segment, allowing Nigerian contractors who work across both residential and commercial HVAC to source the full copper size range from a single WESTRON® brand order from Al Waleed.

Single Commercial Invoice

A consolidated order of WESTRON® refrigerant, WESTRON® copper coil, compressors, SIGMA tools, and other HVAC parts from Al Waleed produces a single commercial invoice covering all items. Nigerian customs clearance at Apapa or Onne Port requires one entry for one consignment — not separate entries for separately sourced products from multiple Dubai suppliers. A single invoice also simplifies the Nigerian importer’s own bookkeeping, supplier payment management, and landed cost calculation per product line.

Lower Per-Unit Shipping Cost

Sea freight cost from Jebel Ali to Apapa is calculated per container or per cubic metre for LCL (less than container load) shipments. Adding copper coil rolls to a shipment that already contains refrigerant cylinders and compressor boxes fills the container volume more efficiently — reducing the per-unit shipping cost allocated to each product line. A Nigerian importer who ships copper separately from their refrigerant and parts orders pays full LCL rates on each shipment. A consolidated order pays one LCL rate on a higher-value, fuller container — a meaningful landed cost advantage at scale.

Simplified Supplier Relationship

A Nigerian HVAC importer managing separate Dubai supplier relationships for refrigerant, copper, compressors, and tools deals with multiple price negotiations, multiple payment transfers, multiple packing lists, and multiple shipment tracking issues every import cycle. Consolidating all of these through Al Waleed as a single Dubai supplier reduces relationship management overhead significantly — one WhatsApp conversation, one quote, one payment, one shipment. This simplification has real commercial value for Nigerian importers managing multiple product categories simultaneously.

WESTRON Brand Consistency for Dealers

Nigerian spare parts dealers who retail both WESTRON® refrigerant and WESTRON® copper coil can merchandise the brand consistently to their contractor customers — reinforcing the WESTRON® brand recognition that already exists through the gas range. A contractor who knows WESTRON® refrigerant from their regular gas purchases is more likely to try WESTRON® copper coil when it is stocked by their usual parts dealer than if it were an unfamiliar brand. Brand consistency at the dealer counter is a small but real sales advantage.

Always Use a Tube Cutter

Cut WESTRON® copper coil with a sharp wheel tube cutter — never a hacksaw. Hacksaw cuts leave metal swarf inside the tube that circulates in the refrigerant circuit on start-up, damaging compressor bearings. Deburr the cut end with the reamer on the cutter before fitting any flare or braze joint.

Braze with Nitrogen Purge

Flow dry nitrogen through the WESTRON® copper tube during all brazing operations. Brazing without nitrogen purge produces internal copper oxide scale at the heat-affected joint zone — scale that contaminates the refrigerant circuit and degrades compressor oil. A slow nitrogen flow at 0.1–0.2 bar is sufficient to displace air from the joint area and prevent internal oxidation.

Insulate All Suction Lines

In Nigeria’s high-humidity coastal cities — Lagos, Port Harcourt, Warri, Calabar — uninsulated suction lines condense moisture continuously. Insulate WESTRON® suction line copper with closed-cell foam insulation sleeve or Armaflex tape on every installation. In northern Nigeria (Kano, Kaduna), insulation also protects rooftop copper runs from UV degradation.

Deep Vacuum Before Charging

After completing the WESTRON® copper line set and connecting to the AC unit, pull a deep vacuum to 500 microns or below before charging WESTRON® refrigerant. The quality of the copper line set means nothing if the refrigerant circuit is charged with residual moisture — moisture that forms acid with the refrigerant and destroys compressor oil within months.
