Alu Simple Fluid

The Alu Simple Fluid is an oil-filled aluminium radiator made with slim and compact vertical flat columns.

The Alu Simple Fluid is heated by using an electric element immersed in the thermodynamic oil inside the radiator. This maintenance-free and specially formulated fluid is designed to distribute heat quickly and evenly across the radiator, which in turn transfers heat to your room via radiation.

The Alu Simple Fluid is practical and user-friendly, guaranteeing maximum flexibility in use. It is therefore an excellent solution when different rooms in the house have different temperature needs.

The Alu Simple Fluid is available in traffic white and anthracite grey.

Integrated control panel

The digital control with LCD screen is located at the top right of the radiator and has numerous functions for efficiency, energy saving and safety. It can also be operated via the included remote control.

Remote control

A portable digital remote control with LCD screen is included, including a bracket for wall mounting.
