Applications
- Drying
- Heat Treating
- Annealing
- Load Banks
- Curing Ovens, Dryers, Ducts, etc.
Features
Versatile - Ideal for both comfort and industrial process air applications. Contact NTT Sales Office for price and availability.
Fins - Greatly increase surface area and permit faster heat transfer to the air, resulting in lower element surface temperatures.
Construction - Element is constructed like the standard tubular element with the addition of continuous spiral fins (4 - 5 per inch) permanently furnace brazed to the sheath.
High Watt Density - Permits use of fewer elements or higher concentration of installed kW for a given area.
Easy Installation - Bending configurations can be designed to fit either round or rectangular ducts. Tight element bends are repressed in hydraulic presses after bending to assure reoccupation of refractory material to eliminate hot spots and electrical insulation voids.
Over Temperature Protection - A high limit temperature cutout is recommended.
Special Features - Sheath material (i.e. Stainless Steel), threaded fittings, length, diameter, volts, watts, special bends, terminals, terminal enclosures, brackets, spacers, etc. Contact your NTT Sales office for price and availability.
