Renewable Design for Flameproof Control System For Electric Heater – Air Duct electric heater – Weineng

Application

Air duct type electric heaters are used for industrial duct heaters, air conditioning duct heaters and air in various industries. By heating the air, the temperature of the output air is increased, and it is generally inserted in the transverse opening of the duct. According to the working temperature of the air duct, it is divided into low temperature, medium temperature and high temperature. According to the wind speed in the air duct, it is divided into low wind speed, medium wind speed and high wind speed.

Energy-saving duct heaters are mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850°C. It has been widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry and universities, etc. It is especially suitable for automatic temperature control and large flow high temperature combined system and accessory test.

The electric air heater has a wide range of use and can heat any gas. The hot air produced is dry and moisture-free, non-conductive, non-burning, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space heats up quickly ( Controllable)

Feature

The electric heating tube adopts outer-wound corrugated stainless steel belt, which increases the heat dissipation area and greatly improves the heat exchange efficiency.
The heater design is reasonable, the wind resistance is small, the heating is uniform, and there is no high and low temperature dead angle
Double protection, good safety performance. A thermostat and a fuse are installed on the heater, which can be used to control the air temperature of the air duct to work under the condition of over-temperature and seamless, ensuring foolproof

Product technical characteristics
Can heat the air to a very high temperature, up to 450 degrees Celsius, the shell temperature is only about 50 degrees Celsius
High efficiency, up to 0.9 or more
The heating and cooling rate is fast, the adjustment is fast and stable, and the controlled air temperature will not lead and lag, which will cause the temperature control to float, which is very suitable for automatic temperature control.
It has good mechanical properties. Because its heating element is made of special alloy material, it has better mechanical properties and strength than any heating element under the impact of high-pressure air flow. This is suitable for systems and systems that need to continuously heat the air for a long time. The accessory test is more advantageous.
When it does not violate the operating regulations, it is durable and the service life can reach several decades
Clean air and small size
