Radium warms the atmosphere by reflecting the heat energy generated by the combustion of the air-gas mixture inside the radiant tubes into the desired environment thanks to parabolic design aluminum reflectors. Radium tube type radiants heat people and objects, ensuring optimal comfort for heating. - The tubular radiant heaters use heat treated aluminum steel fillet tubes. - Efficient, low capacity, efficient heating to end users. - Fillet tubes are designed for high performance aluminas, made of calorized steel coils to aluminum. - Production process is subject to special processes to show the highest radiation capability in the areas of use. Heat Dissipation Radium tube radiant device adjacent temperature distribution isohips curve Y.I.B the ability to address a large area, as in the curve, is due to the high radiant efficiency of the radiant tube material to radiate. Steel-specific radiant tubes to aluminum, with a radiant efficiency of 92%. High efficiency is achieved by minimizing heat losses. Importance Of Tube On Piped Radiant Devices The flame, created by the air-fuel mixture in the burner, flows through the pipe into the chimney gas and the waste gas is expelled. The energy generated by the burning gas in the pipe is transmitted to the pipe, which emits its energy by radiating the outside area. Maximum heat transfer and radiation capability depend on the quality and suitability of the fillet tube. Reflectors of Radium Radiant Heaters The radiation beams coming out of the pipe surface are indicated by red color (straight line), and the beams reflected from the reflector are indicated by orange (dashed line). The choice of reflector material is crucial; reflective aluminum with high reflective properties is used. Reflectors are used to redirect radiation from dead spots (usually facing the ceiling) back to the desired area, increasing radiation capacity and supporting surface heating. Emissivity Emissivity is a dimensionless number that measures how well an object emits energy compared to a black body. It depends on body temperature, wavelength, and angle of propagation. According to Kirchhoff’s law, the emission coefficient equals the absorption coefficient. For real bodies, emissivity depends on surface structure and temperature, varying between 0 and 1. Device Controls Different scenarios and control elements are available: - Remote control - Integration via control board - Pako switched manual control - Thermostat-switched automatic control - Integration into automation system (Control via Scada) The variety of control scenarios allows products to be managed correctly and as desired. The most appropriate scenario is selected based on on-site use and site conditions, facilitating fuel savings and long-lasting, trouble-free service. - Password protection - Heat preservation mode - Freeze protection feature - 24/7 programmable feature - 128 x 64 graphic LCD display - Communication port with computer - Automatic and manual control - Ability to connect external temperature sensor - Control of 8 independent zones and 32 devices in total Analog Room Thermostat Automatically turns off the device when the set temperature is reached and restarts when the temperature drops, saving fuel. Temperature Sensor Freeze protection mode, modulating control, temperature adjustment via the device. Provides fuel saving by reducing modulation value as the programmed temperature is approached. Pako Switched Manual Control Step-adjusted manual control via the pako switch for local solutions. Devices can be operated at the desired level, and heaters can be controlled with an independent step setting. Remote Control Simple-to-use device with 3 buttons for on-off, heat setting, and reset. All Daygas products can be controlled remotely with a single remote.
