  • What is the basic difference between finned and unfinned tubular elements in Air Duct Heaters, and what effect does it have on the performance?
    Some of the designs used with air duct heaters include finned tubular elements and have the wattage per cross-sectional area of the duct for transfer of heat for effectiveness. These components have a steel tube with a corrugated steel fin wrapped around it, brazed together, to multiply the resistance against corrosion in such elements that are subjected to humid environments and areas with corrosive chemical contaminants. They are designed for low maintenance and to provide lower operating temperatures, making them energy savers. These are special order unfinned tubular elements where the tubes are made of steel or stainless steel without fins to apply for areas where minimal electrical shock hazards are prioritized. They can be mounted very close to the register or the grille due to design, which allows a more direct approach to heating. This is probably less effective than the elements in even heat distribution.
  • Why might one choose finned tubular elements over unfinned tubular elements for their air duct heater applications?
    The selection of finned or unfinned tubular elements largely relates to the required application of heat. Finned tubular elements are, therefore, preferred and suitable for general heating, mainly where the environment comprises air containing humid, corrosive contaminants. The design is such that operating temperatures are reduced so that the equipment can operate with low power consumption, thus power-saving equipment. Uncommon and usually used in only some peculiar applications, tubular unfinned elements are recommended for installations that must particularly protect against a diminishment of the risk of electric shock or for areas where proximity to registers or grills prohibits the use of fins. The other difference in these two simply is the ability to withstand some environment condition and efficiency in heating required.
  • How do air duct heaters works ?
    Sinton air duct heaters are designed for primary and secondary, as well as secondary, and auxiliary space heating, reheating, and variable air volume heating. They work through the actual flow of the air ventilation system, therefore gaining comfort and efficiency during industrial procedures. Its package software specifies the wiring and the configuration of the coils, supports racks of the elements, and accessories, together with the sheet metals and controls. Quick design changes can be done to meet specific company requirements, with this software, and it helps these heaters to take over every need in the industry. Generally, air duct heaters are manufactured in a variety of sizes and dimensions. The scope of the size and type covers three major categories intended for a specific heating need, whether it is inserted or flanged. This includes finned tubular heating elements, open coil heaters, and tubular duct heaters.
