1. Gas duct heaters are typically used to heat air, nitrogen, and other gases, capable of heating the gas to the required temperature in a very short time.
2. Liquid duct heaters are typically used to heat water, oil, solutions, and other fluids, ensuring the outlet temperature meets the process requirements.
A duct heater is an electric heating device that installs heating tubes inside a cylindrical insulated container to heat gases or liquids. Duct heaters feature fast heating speed, good thermal insulation performance, and high heating temperature.
A duct heater consists of two parts: the body and the control system. The heating element uses stainless steel tubes as protective sleeves, high-temperature resistance alloy wires, and crystalline magnesium oxide powder, formed through a compression process. The control part adopts advanced digital circuits, integrated circuit triggers, high reverse voltage thyristors, etc., to form an adjustable temperature measurement and constant temperature system, ensuring the normal operation of the electric heater.
1. The duct heater adopts a stainless steel cylinder, which is small in size, takes up little space, and is easy to move. It has strong corrosion resistance. A thickened insulation layer is used between the stainless steel inner tank and the outer shell, resulting in low heat loss, temperature retention, and energy saving.
4. The duct heater is equipped with a temperature controller from a well-known domestic brand, allowing users to freely set the temperature. It is fully configured with an overheat protector to control temperature and protect against water shortage and over-temperature, preventing damage to the heating elements and system.
1. Vertical duct heaters occupy a small footprint but have height requirements, while horizontal ones occupy a large footprint but have no height requirements.
2. The materials for vertical and horizontal duct heaters include: carbon steel, stainless steel SUS304, stainless steel SUS316L, stainless steel 310S, etc. Appropriate materials are selected based on different process requirements for heating. The duct heater uses flange-type electric heating tubes and is equipped with professionally designed baffles to ensure uniform heating of the electric heating tubes and full absorption of heat by the heating medium.
4. For high-temperature requirements (outlet temperature greater than 600°C), the outlet temperature can reach 800°C.
Widely used in aerospace, ordnance industry, chemical industry, and many scientific research and production laboratories in universities. It is especially suitable for automatic temperature control and high-flow high-temperature combined systems and accessory tests. The heating medium is non-conductive, non-flammable, non-explosive, non-corrosive, non-polluting, safe and reliable, and the heated space heats up quickly (controllable).
