Applications

RBLL-DC350-A1 is designed specifically for standard under-window and niche installations. It can be used confidently across a wide range of applications, including apartments, offices, hotels and large residential developments. The low water content allows the system to heat up quickly, reducing energy consumption; aluminium's high thermal conductivity ensures room temperature stabilises rapidly.

Why Choose RBLL-DC350-A1?

• Fast Heat-Up: Thanks to aluminium's high thermal conductivity, the radiator reaches full output within minutes of the system starting.
• Low Water Content: With 330 ml water per section, system losses are minimised and energy bills reduced.
• Long Service Life: AlSi12 alloy structure and electrostatic powder coating deliver 30+ years of performance.
• Flexible Sectioning: Project-specific section counts can be specified and grouped at the factory.
• OEM Manufacturing: Private-label production available with custom RAL colours, branding and packaging.

Compatibility and Connections

RBLL-DC350-A1 is compatible with all standard valves and thermostatic heads on the market, with left, right or bottom centre connection options. When section count is confirmed, a leak-free assembly is achieved using special nipples and EPDM seals. Standard packaging dimensions and barcodes simplify logistics.
