Air heating system GSR1 series

The only optional Fraccaro patented condensing unit Up to 107% thermal efficiency and up to 50% less fuel compared to any hot air generator or underfloor heating system with a condensing boiler. EUROPEAN PATENT No. 94115945.1 The Girad radiant modules with a condensing unit recovers nearly all of the latent heat coming from the vapor produced in the combustion of gaseous fuels, and in particular of natural gases. Thanks to special elliptical stainless steel exchangers absorbing the latent heat, the average efficiency of the burner, and the temperature of the fumes is about 45-50°C. The recovered heat is released into the atmosphere through unit heaters. Thus, Girad’s condensing unit achieves total efficiency averaging over 107%. This result, alongside the performance of our radiant strips, offers an ideal solution for industrial heating. The total savings produced by a Girad condensing unit may reach 65% compared to conventional hot air heating systems. 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.
