Armaflex Class O Endless Tube Air Conditioning Coils

Armaflex Class O Endless Tube Air Conditioning Coils are the ultimate insulation solution for HVAC, refrigeration, and air conditioning systems. Manufactured by Armacell, these continuous coils of closed-cell nitrile rubber foam offer exceptional thermal efficiency with a conductivity of 0.033 W/mK at 0°C, minimizing heat loss and preventing condensation on cold pipes. Designed specifically for air conditioning fitters and refrigeration engineers, the endless tube format eliminates the need for multiple joints, reducing installation time, waste, and potential leak points while ensuring a seamless, professional finish.

This Class O fire-rated insulation meets stringent UK building regulations (BS 476 Parts 6 & 7), providing low flame spread and minimal smoke development for enhanced safety in commercial and residential applications. Its built-in Microban® antimicrobial protection resists mould and bacteria growth, making it ideal for hygiene-sensitive environments like hospitals, schools, and food processing facilities. Flexible and lightweight, Armaflex Endless Tube Coils adapt easily to complex pipework, fitting copper and steel pipes from 6mm to 28mm in diameter with insulation thicknesses of 9mm or 13mm.

Perfect for split air-con units, chillers, and refrigeration lines, these coils withstand temperatures from -50°C to +110°C and resist UV, oil, and weathering, ensuring long-term durability. Available in practical lengths (e.g., 25m, 50m coils, depending on size), they streamline bulk installations.
