RBLL-DC300-A

RBLL-DC300-A Aluminium Cast Radiator — Overview

RBLL-DC300-A is a 300 mm centre-distance aluminium cast radiator from Radobella's EN 442-certified RBLL-DC series. Manufactured from high-purity AlSi12 alloy using pressure-die casting, this model withstands the most demanding conditions of modern central heating systems with 16 bar working pressure and 110°C temperature tolerance.

With 87.0 W/section (ΔT50) output, RBLL-DC300-A is ideal for small rooms, corridors and renovation projects. Section count can be freely adjusted to suit any project requirement; OEM and private-label manufacturing options are also available.

Applications

RBLL-DC300-A is designed specifically for low window sills and compact enclosures. It can be used confidently across a wide range of applications, including small rooms, corridors and renovation projects. 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-DC300-A?

• 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 280 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-DC300-A 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.
