RBLL-BM350-D2 Aluminium Bimetal Radiator — Overview
RBLL-BM350-D2 is a 350 mm centre-distance aluminium bimetal radiator from Radobella's RBLL-BM series. Combining an aluminium outer body with a steel inner core, its bimetal construction offers superior resistance to aggressive water chemistry, high pH levels and mineral content — making it the preferred choice wherever water quality cannot be fully controlled.
With 98.5 W/section (ΔT50) output and EN 442 certification, RBLL-BM350-D2 provides a comprehensive solution for standard residential, hotel and commercial building projects projects. Max. 16 bar working pressure and 110°C temperature tolerance meet European and Gulf market requirements.

The Bimetal Advantage
Standard aluminium radiators offer excellent thermal conductivity, but in some central heating systems — high pH, mineral-rich or acidic water — long-term corrosion is a real risk. RBLL-BM350-D2's steel inner core eliminates this:
- Corrosion Resistance: The steel inner tube forms the water-contact surface, isolating the aluminium body.
- Wide pH Tolerance: Operates reliably in pH 6.5–9.0 systems; the safe choice for older installations.
- Long System Life: Aluminium's lightness combined with steel's durability — 30+ years of performance.
- Aluminium Exterior: Fast heat-up, high thermal conductivity and a refined appearance are retained.
Applications
RBLL-BM350-D2 is ideal for standard residential, hotel and commercial building projects. It is used with confidence in buildings with older heating systems or unknown water quality, public buildings such as hospitals and schools, commercial retrofit projects, and export projects.
