Aluminium radiator kfa² G500F (model 777-100-61) graphite — sectional heating radiator

Aluminium radiator kfa² G500F (model 777-100-61) in graphite is a sectional heating radiator designed for central heating systems. Constructed from modular aluminium sections, it combines convective and radiant heat transfer to warm indoor spaces efficiently. The graphite finish provides a neutral, contemporary appearance suitable for residential and commercial interiors where compact sectional radiators are required. The radiator is intended for room heating, replacement of older radiators, or installation in multi-unit buildings connected to a central hot-water system.

Advantages

This sectional aluminium radiator offers a high thermal conductivity typical of aluminium, enabling quick warm-up and responsive temperature changes. Its sectional design allows for flexible sizing by adding or removing sections to match room heat demand. The graphite surface is corrosion-resistant and provides a uniform finish that integrates with modern décor. The radiator's lightweight construction simplifies handling and installation compared with heavier materials, while its aluminium body supports efficient convective and radiant heat distribution.

Suitable for

• Heating living rooms, bedrooms and small to medium-sized commercial spaces
• Replacement of cast-iron or steel radiators with a more responsive aluminium option
• Installation in apartments, offices and multi-unit residential buildings with central hot-water systems
• Situations requiring compact sectional radiators with customizable length

Key specifications

• Material: aluminium sections
• Finish: graphite-colored coating
• Design: sectional modular construction for adjustable length
• Heat output principle: combined convective and radiant heat transfer
• Intended connection: central hot-water heating systems (standard sectional radiator connections)
• Installation type: wall-mounted with brackets (standard for sectional radiators)

How to use

Install the radiator on a load-bearing wall using appropriate brackets and fasteners sized for the radiator weight and wall material. Connect to the building hot-water heating circuit using compatible valves and fittings; ensure the system is depressurised during connection and that sealing materials suitable for heating systems are used. After installation, bleed air from the radiator via the bleed valve to remove trapped air and check for leaks at all joints and connections. Set the room thermostat or individual radiator valve to the desired temperature and allow the system to stabilise; the aluminium sections will heat up rapidly, providing convective and radiant warmth.

Usage recommendations

For optimal performance, match the number of sections to the calculated heat loss of the room. Use corrosion-inhibiting additives in closed central heating systems as recommended by system manufacturers. Regularly bleed radiators to maintain efficiency and check brackets and fittings periodically for secure mounting. Avoid covering the radiator with insulating materials to preserve convective heat circulation.
