The GIRAD radiating belt is a suspended radiation-heating unit suitable for medium to large areas. A system with GIRAD appliances consists of a heat production unit fuelled by gas (methane or LPG) and a Radiating Belt, i.e. a tube providing a closed circuit at lower than environmental pressure (as required by Italian law). The GIRAD radiating belt is able to adjust its power and shape according to the features of every single building.
The maximum temperature of the Radiating Belt is controlled by an adjustable thermostat and can be set up in a range of 100 to 300°C (212 to 572°F) according to the requirements. A fan in the final section of the circuit creates low pressure inside the circuit. The GIRAD system adapts its shape and power to the characteristics of the building. After installation, a convector fluid is circulated at high speed inside the Radiating Belt. The fluid consists of a mixture of hot air and burned gas. When the set temperature is reached, the burner is cut out, while the combustion unit fan continues to operate until the radiating circuit reaches the minimum set temperature. The GIRAD system is designed to have the heat production unit and burner located outside the building. The gas supply line area is also located outside.
High-quality components and care during assembly place GIRAD at the maximum level regarding safety and efficiency. This system is protected by the International Patent “Fraccaro” nr. 94115945.1.
The Girad belt is designed and produced with specific engineering characteristics:
• Design : inspired by the most modern and efficient sheet steel machining to provide adequate accommodation for the appliance.
• Flexibility : all the burners have a 2- or 3- stage power-module.
• Material : materials used are suitable to resist at very low external temperatures and in a very wide range of weather conditions.
GIRAD can have the heating unit and its burner installed outside (either hanging on a wall or upon the roof) or even inside the building, according to requirements by law.
