PANRAD: Radiant tube modules

Equipments suited for all environments with great height (form 4 to 20 meters) or with high thermal dispersion.
It includes a burner unit and a heat exchanger tube which reaches the temperature of 400 ÷ 550 °C., providing a very high radiation efficiency, also by means of the reflecting cover located over the tubes, which focuses the thermal flow downwards.

By means of a centralized equipment control system it is possible to heat only the areas concerned by operations.

PANRAD radiant tube Modules are now internationally supplied. The PANRAD radiant tube range consists essentially of a heat production unit with thermal power range of 10 to 50 kW, a system of radiating tubes of 6-9-12 meters (19.7-29.5-39.4 feet) in length, plus control and safety devices. The combustion unit burns the air/gas mixture, and the split flame heats the fluid that circulates inside the radiating tube system consisting of a delivery tube, a U-connection and a return tube. A suction unit under the return tube creates low pressure inside the tubes and, as a result, the fluid is conveyed through all the radiating tubes, which, in turn, begin to radiate. A reflecting dish in aluminium alloy installed above the emitting tubes ensures that radiation is fully concentrated toward the floor and the objects on it. This dish recovers all radiation that would be otherwise lost in the upper areas of the building.

Burner: the burners designed by FRACCARO S.r.l. are all air-tight, combustion air is sucked in from outside, burned gas is discharged outside, and the values of CO and NOx emitted into the atmosphere are well below the most restrictive European limits.

Radiant Tube : the maximum temperature, reached through the effect of burned gas circulating inside the tube, is very high and amounts to approximately 500°C (842°F) at the hottest point. The delivery tube is connected to the return tube by a union head. A compensating expanded section is connected to the head, serving to balance the greater thermal expansion of the delivery tube with respect to the return tube.

Reflector : the reflecting dish is very important because the higher the quantity of radiating heat reaches the floor, the lower the system operating costs are. The reflector is in aluminium alloy with mirror finish, and has an absorption coefficient of 0.04. The Fraccaro range also includes reflectors in hammered aluminium suitable for very low-level installations; reflectors with fibreglass insulation for extra recovery of lost heat, reflectors in stainless steel INOX for installation in areas where highly corrosive substances are machined.
