Features of mine air duct heater:
1. It can heat the air to a very high temperature, up to 450 ℃, and the shell temperature is only about 50 ℃.
2. High efficiency: above 0.9.
3. Heating and cooling rate block, up to 10 ℃ / s, fast and stable regulation. It is suitable for automatic control because it can not lead or lag the controlled air temperature and make the temperature control drift indefinitely.
4. Good mechanical properties: because its heating body is made of special alloy material, under the impact of high-pressure air flow, it has better mechanical properties and strength than any heating body, which is more advantageous for the system and accessories requiring continuous air heating for a long time.
5. Durable, in strict accordance with the use of regulations, the life of up to ten years.
6. Clean air, good for environmental protection.
7. According to the actual needs of users, we can provide the design scheme and customize various types of air electric heaters.
The mine air duct heater is mainly used to heat the air in the air duct. The specification is divided into three forms of low temperature, medium temperature and high temperature. The common thing in the structure is that the steel plate is used to support the electric heating pipe to reduce the vibration of the electric heating pipe. The junction box is equipped with the over temperature control device. In addition, in the aspect of control, in addition to over temperature protection, a combined transport device is also installed between the fan and the heater to ensure that the electric heater must be started after the fan is started, and a differential pressure device is added before and after the heater to prevent fan failure. Generally, the gas pressure heated by the channel heater should not exceed 0.3kg/cm2. If the above pressure needs to be exceeded, please select the circulating electric heater; low temperature type The high temperature of heater gas heating Zui shall not exceed 160 ℃; the medium temperature type shall not exceed 260 ℃; the high temperature type shall not exceed 500 ℃.
The air electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, with Zui as high as 650 ℃. It has been widely used in drying tunnel, drying room, aging room, high temperature room, etc,. It is especially suitable for automatic temperature control and large flow high temperature heater. The electric air heater can be used in a wide range: it can heat any gas. The hot air produced is dry, non-conductive, non combustible, non explosive, non chemical corrosive, non polluting, safe and reliable, and the heated space can be heated quickly (controllable).
Specification and model: single power from 2kW to 500kW series.
