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.

KEY BENEFITS

  • COMBUSTION EFFICIENCY up to 107%*.
  • 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. All this ensures high reliability and long-term safety.

OTHER ADVANTAGES

  • NO AIR STRATIFICATION or rather no warm air shall accumulate in the high areas of the room being heated; on the contrary, as far as the air goes upwards, the air temperature itself decreases.
  • EXCELLENT THERMAL EMISSION generated by the large radiating surface with high emissivity.
  • HEALTHIER AND CLEANER AIR There are no convective motions and consequent raise of dust, keeping the air healthy and clean.
  • COMFORT TO CURRENT STANDARDS Our long experience stretching back over thirty years of activity, added to our participation in work groups specifying standards for products, make Fraccaro an ideal partner in this specific sector of heating technology.
  • EASY, RAPID INSTALLATION thanks to an easy assembling procedure and installation on the ceiling with chains.
  • NO FLOOR OR WALL SPACE IS REQUIRED as our GIRAD Radiant modules are installed on the ceiling.
  • NO DANGER OF FROST as the lack of carrying fluids, such as hot water or steam, makes it possible to shut down the system for long periods without any unfortunate consequences.
  • UNIFORMITY OF TEMPERATURE the heat produced through radiation by our Radiant Modules creates uniform temperature horizontally through the building, better than with any type of traditional heating.
  • HIGHLY ECOLOGICAL as it allows for fuel saving, with great combustion performance and very low emissions of pollutants.
  • MODULAR DESIGN i.e. for large surfaces more than one units are to be installed.
  • MODULATING OPERATION of generators, so as to control the radiating heat emission according to the external temperature.
  • NO AIR STRATIFICATION or rather no warm air shall accumulate in the high areas of the room being heated; on the contrary, as far as the air goes upwards, the air temperature itself decreases.
  • RAPID WARM-UP due to lack of intermediate fluids requiring heating.
  • CONFORM TO CURRENT STANDARDS Our long experience stretching back over thirty years of activity, added to our participation in work groups specifying standards for products, make Fraccaro an ideal partner in this specific sector of heating technology.

PRE-ASSEMBLED MODULES

The radiant module is realized with a supporting frame in zinc-coated steel. The frame supports one or two pipes in aluminized steel treated with silicone paint and having insulating fiberglass panels on three sides. The pre-assembled modules in 1.5, 3 and 6-meter length allow a very flexible application of the circuits whose length and shape can vary according to the requirements of the building to be heated.
They are produced and pre-assembled in our factory to make the installation job easier and quicker. Thanks to the special chain connection to the supporting frame, the pipes are free to move while heating or cooling assuring a very long lasting to our modules.

MODULE CONNECTION

The flanged cone-shape joints ensure perfect pipe tightness; during the installation they avoid problems coming from the traditional connections with silicone, gaskets or other adhesive components.
The bayonet joint of the radiant modules ensure the perfect tightness of the radiant circuit.

Vantaggi

The industry requires powerful cooling systems and effective, because the livability has a direct influence on the productivity of people. At the same time, however, for large spaces and volumes at stake, every company must be able to rely on maximum efficiency, to avoid wastage and consequent unsustainable costs.
A radiant system Fraccaro can reduce energy consumption up to 60%, with a sharp cut of the energy burden on the budgets.
