Finned Tubular Duct Heaters
There are numerous applications of heaters at industrial and commercial sites. Whether it’s an open coil duct heater, a tubular or a finned tubular duct heater, each duct heater serves the main purpose which remains the same. However, the type may vary based on their construction, working, advantages, disadvantages and functionality differences. The types of heaters used though can vary from person to person and industry to industry. While there are a wide variety of heaters available in the market, some seem to standout more than others. Duct Heaters in general and Tubular Duct Heaters in particular fall in that category. They are heaters designed for a variety of applications that include but are not limited to space heating, etc. These heaters are one of the widely-in-demand heaters of the market, and not one but several industries make use of them on a daily basis. Duct heaters can be broadly categorized into two categories, air duct heaters and process heaters. While both of these categories are variations of the same model, their uses are considerably different. Air duct heaters are used for heating of the ventilation systems in industries and to provide comfort to other heating applications while they are in play. Process duct heaters on the other hand are used for operations that involve industrial process heating such as ovens etc. They specialize in handling situations that require forced circulation or recirculation of heat. Key Features of Tubular Duct Heaters Most duct heaters are designed in a similar way to one another. Yet their designs can have variations as per their heating elements and in relation to the industry they are to be used in and the application that they will be expected to fulfill. Here is a lowdown on some of features that a typical tubular duct heater is made up of. It should be remember that each design of tubular duct heater can be varied as per the demands of the customer in line with the application and industrial operation requirements. Variation of tensions, coming in Single and three-phase tensions They come with a 16-gauge satin coat steel These heaters are laced with 2′ vertical and horizontal dimensional increments for faster delivery Strengthened Stainless steel supports Field replaceable heating elements, if required Exclusive modular construction with stock frame components used with A terminal enclosure that has been built for general purpose A Secondary linear cutout: A 3 1/2′ (90 mm) thick insulation to keep the heat from escaping from outlets other than the original one 1/4′ (6 mm) inside diameter thermowell Manual reset with back-up magnetic contactor on units of 300V, 30 kW and less 277/600 VAC 225 F (107 C) 25/10 AMP non-inductive Built stainless steel frames available upon request American and Canadian Standards Associations (CSA, CSAus) certified Primary linear cutout: 277/600 VAC 160 F (71 C) 25/10 AMP non-inductive Special sizes, wattages, and materials available upon request of the customer Specifications: Finned tubulars increase surface areas extending the 035 inch wall thickness allowing for higher watt densities Available in multiple stages if required Airflow switches are available to prevent the heater from operating unless the air is flowing Disk type thermal cutouts are available Two frame constructions are available – Slip in heaters have frame dimensions sized so that the entire frame slides though a rectangular opening in the side of the duct Highest quality copper stranded wiring is used with wiring diagrams All frames are made of heavy gauge corrosion resistant steel. Stainless steel frames are also available upon request.
