What is CBM copper tube single M1 3/4 used for?

CBM pre-insulated copper tube is designed for refrigeration and air-conditioning systems in commercial and industrial applications. The M1 fire rating suits installations in buildings requiring flame-retardant materials per EN12735-1 standard, common in Singapore's hospitality, data centre, and manufacturing sectors.

How do you install pre-insulated copper tubing?

Pre-insulated copper tube installation requires secure clipping every 1–1.5 metres to prevent sagging, careful handling to avoid insulation damage, and proper derating of refrigerant capacity due to insulation thickness. Always consult system design documentation and local building codes before installation.
