Air heating system Girad

The installation of the Radiant Modules consists of a patented heat generator, a single or double-pipe radiant circuit and a thermoregulation digital device. The radiant circuit is a closed ring having go and return tubes working in vacuum condition. The gas or gas-oil burner produces a carrying fluid (a mixture of air and burned gases) which circulates at high speed inside the tubes of the radiant circuit. The tubes reach a superficial temperature from 100°C to 300°C (according to the requirements) producing the radiant energy necessary to provide the required environmental comfort. The pipes are in aluminized steel, treated with special silicone paint and insulated with fiberglass panels on three sides. The radiant circuits are pre-assembled and tested in our factory; their installation on site turns out to be very easy also thanks to their flanged joints. Key benefits COMBUSTION EFFICIENCY up to 95% or 107% in models equipped with condensing unit*. ECOMIX BURNER air-stream gas burner with VENTURI tubes working in constant proportional modulation. ECOSAVING DEVICE that controls the chimney lock-gate and allows to keep optimal combustion efficiency at any power level**. PRE-ASSEMBLED MODULES They are produced and assembled in our factory to make the installation job easier and quicker***. THERMAL POWER up to 300kW and circuit lenght up to 160m. DIGITAL THERMAL CONTROL allows you to operate the system from remote stations and get remote assistance service (optional). MINIMUM MAINTENANCE through the reliability of all components and exacting tests complying with European standards both in the assembly line and in the in-house laboratory.
