DYK-75 (II) Air Electric Heater
1. Purpose and Features 
DYK-75 (II) Air Electric Heater is suitable for heating the aeration air of air conveying chute in power stations, heating the aeration air of ash hopper in electrostatic precipitators and ash silos, as well as other applications requiring air heating. This equipment consists of two parts: the air electric heater body and the control system. The heating element uses 1Cr18Ni9Ti stainless steel tube as the protective sleeve, 0Cr27Al7MO2 high-temperature resistance alloy wire, 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. The heating element adopts a straight tube type instead of a U-shaped structure, which can be easily installed and removed with a special wrench. The electric heating tube has good thermal conductivity and excellent insulation. A guide plate is installed inside the heater to ensure uniform heating. 
The air electric heater control cabinet has interlocking control functions with the aeration fan, as well as local control and remote control interfaces. When the equipment suddenly stops and restarts, the control cabinet can automatically adjust smoothly.

Product Overview:
This electric heater heats the fluid through forced convection. That is, a pump pumps the fluid into the heating chamber at one end of the heater, and after heating, it flows out from the other end. It is a heating method that uses a pump for forced circulation. Compared with traditional heating methods, it has significant energy savings, scientific process, easy installation and use, and obvious economic benefits.
DYK-75 (II) Air Electric Heater
1. Small size, high power.
The heater mainly uses bundled tubular heating elements internally, with each bundled tubular electric heating element having a maximum power of up to 2000KW.
2. Fast thermal response, high temperature control accuracy, high overall thermal efficiency.
3. Wide application range, strong adaptability.
This heater can be used in explosion-proof or ordinary environments, with an explosion-proof rating up to Class B and Class C, and a pressure resistance of up to 20Mpa. The cylinder can be installed vertically or horizontally according to user needs.
4. High heating temperature.
The maximum working temperature of the heater design can reach 650°C, which is not achievable by ordinary heat exchangers.
5. Fully automatic control.
Through the circuit design of this heater, parameters such as outlet temperature, pressure, and flow can be automatically controlled, and it can be connected to a computer for human-machine interaction.
6. Long life, high reliability.
This heater is made of special electric heating materials, and the design power load is relatively conservative. The heater adopts multiple protections, greatly increasing its safety and service life.
