Each coil and straight length undergoes rigorous internal cleaning and dehydration processes to ensure maximum system purity. Order direct from Pirouz Ltd for fast UK delivery, expert technical guidance, and dedicated support for trade installers.
Why Refrigeration Grade Copper Tube Matters
Standard plumbing pipe is unsuitable for high pressure refrigeration systems and air conditioning units. Refrigeration grade copper tube, often referred to as ACR tubing, is specially manufactured to handle higher operating pressures and specialized synthetic or natural refrigerants. The internal surfaces are thoroughly cleaned and nitrogen purged during production to eliminate moisture, residual oils, and microscopic debris that could harm sensitive expansion valves or compressors.
In addition to internal cleanliness, ACR copper tube features precise dimensional control. Accurate outer diameter and wall thickness tolerances are vital for creating sound, leak free brazed joints. Using non certified tubing risks premature corrosion, refrigerant leakage, and system failure, making compliant copper piping essential for professional contractors.
Technical Specifications and Quality Standards
Our comprehensive selection of copper tube meets or exceeds leading international engineering standards. We source products crafted from high purity phosphorus deoxidised copper (Cu-DHP), providing superior ductility, structural strength, and resistance to corrosion.
- Manufacturing Standard: BS EN 12735-1 (Seamless round copper tubes for air conditioning and refrigeration).
- Material Composition: Minimum 99.90% Copper (Cu-DHP), deoxidised with phosphorus for high weldability and brazing performance.
- Internal Cleanliness: Maximum residual soluble residue below 0.038 g/m², ensuring protection against system contamination.
- End Finishing: Every length and coil is capped or plugged at both ends immediately after manufacture to preserve internal dryness.
- Refrigerant Compatibility: Suitable for standard HFC, HFO, and HC refrigerants including R404A, R134a, R410A, R32, R290, and high pressure CO2 (R744) systems.
Available Sizes, Temper States, and Packaging
Different installation scenarios require specific tube temper states. Pirouz Ltd stocks both soft annealed coils and hard drawn straight lengths to match your exact job specifications.
Soft Annealed Copper Coils (R220)
Soft copper coils offer maximum flexibility, allowing installers to bend and route pipework through tight spaces without special tooling. This reduces the total number of brazed fittings required, cutting installation time and minimizing potential leak points.
- Standard OD Sizes: 1/4 in (6.35 mm), 3/8 in (9.52 mm), 1/2 in (12.70 mm), 5/8 in (15.88 mm), 3/4 in (19.05 mm), and 7/8 in (22.22 mm).
- Coil Lengths: Available in convenient 15 metre and 30 metre rolls.
- Ideal Applications: Split system interconnections, complex suction lines, condensate drainage runs, and retrofitting existing cold stores.
Hard Drawn and Half-Hard Straight Lengths (R290 / R250)
Straight lengths provide a rigid, aesthetically neat finish for long horizontal and vertical runs. Rigid copper offers superior structural stability and higher bursting pressure safety margins for high capacity commercial plant rooms.
- Standard OD Sizes: 1/2 in through to 2-1/8 in (54 mm) and larger upon request.
- Standard Lengths: Supplied in standard 3 metre and 5 metre rigid lengths.
- Ideal Applications: Main liquid and suction headers, multi compressor rack interconnects, large walk in cooler pipework, and industrial refrigeration runs.
Key Performance Advantages of Pirouz Copper Piping
Investing in high quality copper tube yields long term benefits for both the contractor and the end user. Here are the core structural and operational advantages of our refrigeration tubing:
- High Thermal Conductivity: Copper rapidly transfers heat, ensuring optimal efficiency across evaporators, heat exchangers, and cooling coils.
- Superior Pressure Resistance: Uniform wall thicknesses allow our tubes to withstand high operating pressures under extreme ambient conditions.
- Corrosion and Oxidation Resistance: High purity Cu-DHP material resists environmental oxidation, extending system operational lifespans in humid or cold environments.
- Brazing Excellence: Clean, smooth surfaces accept silver brazing alloys readily, forming high strength metallurgical bonds that resist thermal cycling shock.
- Eco Friendly Recyclability: Copper is a 100% recyclable material, aligning with modern environmental directives and sustainable building guidelines.
Applications in Cold Rooms and Commercial Cooling
Commercial refrigeration systems rely heavily on robust pipework to transport high pressure refrigerants cleanly and efficiently. As a primary UK supplier of cold room doors, panels, and refrigeration components, Pirouz Ltd provides complete piping solutions for diverse cooling setups.
Our copper tube products are widely deployed across walk in freezers, cold storage warehouses, display cabinets, food processing facilities, and medical cold storage units. From small single split outdoor condensing units to complex central rack installations, our copper tubing delivers reliable performance under demanding conditions.
Trade Pricing and Fast UK Wide Delivery
At Pirouz Ltd, we appreciate that trade contractors need reliable supply chains and fair pricing to keep projects running on schedule. We source large volumes directly, passing maximum trade savings on to refrigeration engineers, HVAC contractors, and facility managers.
We hold extensive inventory at our central Harlow warehouse (Unit 10, Harlow Mill Business Centre, Harlow, CM20 2FD). This enables rapid order processing, fast dispatch across the United Kingdom, and immediate trade counter collection options for urgent repairs or local installations.
Frequently Asked Questions
What is the difference between EN 1057 and EN 12735-1 copper tube?
BS EN 1057 applies to standard water and gas plumbing copper pipe. BS EN 12735-1 is the specific European standard for air conditioning and refrigeration copper tube. EN 12735-1 tube undergoes internal cleaning, dehydration, and end capping to prevent contamination in sealed cooling circuits.
Can I use soft copper coils for high pressure refrigerants like R410A or R32?
Yes, provided the specific wall thickness meets the working pressure requirements of the system. Our soft copper coils are manufactured to wall thicknesses that satisfy the pressure demands of modern HFC and HFO refrigerants when installed according to standard engineering practices.
How is copper tube delivered to prevent damage?
Soft copper coils are individually shrink wrapped or boxed, while hard straight lengths are securely bundled and protected. End caps remain firmly in place during transit to guarantee internal cleanliness upon arrival at your job site.
Do you offer trade discounts for bulk purchases?
Yes, Pirouz Ltd offers competitive trade pricing structures and bulk discounts for contractors, installers, and volume buyers. Contact our sales team to discuss project quantities and secure a custom trade quote.
