What is the Industrial Electric Fan Heater?

An electric fan heater is a device that emits warm air by consuming electrical energy. Industrial electric fan heaters are an excellent way to heat large spaces quickly and efficiently. They are robust, durable, and can withstand harsh environments, making them ideal for use in warehouses, factories, and other industrial settings. ATO industrial automation currently has 2/3/5/9/15KW industrial electric fan heaters on sale. In this blog, ATO will discuss what an industrial electric fan heater is, along with the main precautions for installation and maintenance techniques.

What an industrial electric fan heater is and apply for?

An electric fan heater is an equipment that uses electrical energy to generate heat and warm air, which is usually used indoors. The low-temperature fluid medium of the electric fan heater passes through the pipeline during the working process, and then enters the input port under the action of pressure, along the specific heat exchange flow channel inside the electric heating container, and uses the path designed by the principle of fluid thermodynamics to take away the high-temperature thermal energy generated in the work of the electric heating element, so that the temperature of the heated medium rises. The outlet of the electric fan heater obtains the high-temperature medium required by the process.

The internal control system of the electric fan heater automatically adjusts the output power of the electric heater according to the temperature sensor signal of the output port, so that the medium temperature of the output port is uniform. When the heating element is overtemperature, the independent overheating protection device of the heating element immediately cuts off the heating power supply to avoid coking, deterioration, and carbonization caused by the overtemperature of the heating material, and in severe cases, the heating element will burn out, which effectively prolongs the service life of the electric heater.

The electric fan heater is a portable and movable device, which is the preferred product for upgrading modern industrial heat sources and is the best hot air source configuration for automated machinery such as hot air conveyor furnaces, drying ovens, ovens, packaging machines, etc.

Industrial electric fan heaters are mainly used in families, factories, and warehouses. It is the best heating facility in outdoor places such as workshops, hospitals, docks, cruise ships, construction sites, warehousing and logistics, underground garages, outdoor performances, exhibitions or press conferences, etc. It can also be used for raw materials such as farm greenhouses, bamboo and woodcraft factories, leather processing factories, building materials, food, maintenance, decoration, industrial products, and agricultural products to dry, heat, keep warm, and antifreeze. The heater is also suitable for heating and warming in large areas and spaces, especially for spraying and rapid drying treatment on the outer surface of the motor, pump, and plastic parts. 

Main precautions for the installation

The electric fan heater is a heating facility that can be used in indoor and outdoor places such as homes, warehouses, hospitals, and outdoor performances, and the main precautions for the installation of electric heaters are as follows:

1. The electric fan heater should be installed away from flammable, explosive, and other dangerous items and gases.
2. The heater should be installed in dry indoor places, even if it’s outdoors, care needs to be taken to avoid moisture. 
3. The space where the electric fan heater is installed should be well-ventilated and cannot be used in a sealed box.
4. The air inlet of the electric heater fan must not be blocked, and the air outlet should also be connected with piping with thermal insulation material. Note: The piping should avoid "four over", not too long, too thin, too bent, or too much. 
5. When the electric fan heater is installed, the air outlet should be within the range of 15° upward inclination and 10° downward tilt, and the inclination of the left and right sides of the body should be within 15°. 
6. The temperature of the air outlet pipe and the air sent by the heater may be very high. To avoid burns, please do not get too close. 

Maintenance tips

1. After a period of driving, the water tank of the heater will have a layer of foreign matter and dust on the surface. If it is not cleaned up, it will affect heat dissipation.
2. The blower motor should be maintained and replaced after a long time of operation, the operation process must be judged and maintained by professionals, can not disassemble the motor privately, which is easy to cause short circuits, and the motor does not rotate, if it is not serious, it will burn the insurance, and if it is serious, it will burn off the wiring harness and cause a fire. 
3. The motor ventilation pipe can not be removed, after removal, it is easy to cause the motor to overheat and burn out.
4. The variable speed resistor can make the motor change gears. If the first and second gears are used for a long time, the resistor will easily burn out and affect normal use. If this problem is found, it should be replaced in time. 
5. After long-term use of the operating system, the operating cable is easy to age and deform, which makes the operation inflexible or not in place. Do not move it rigidly to avoid damage to parts. If this problem is found, it should be judged at the maintenance station, and repaired and replaced according to the specific situation. 
6. Ventilation pipes, that is, No.1 and No.2 hoses of heaters, are prone to aging and cracks due to long-term use at high temperatures. If problems are found, they should be replaced in time to avoid water leakage, resulting in excessive water temperature and deformation of the engine cylinder head.
7. When the temperature is below 0 °C in winter, there will be a layer of ice and frost on the front windshield. Start the engine, when the water temperature rises above 40 °C, put the operation according to the sign to the defrosting position, circulate to the indoor circulation position, open the blower motor, and put it in the third gear position. At this time, the motor speed is the highest, making it run for 3-5 minutes, and then according to the defrosting situation, the gear can be put to the first and second gear positions. During this period, the driver had better not leave the cab. If the motor does not turn, the motor gear should be returned to the closed position immediately to avoid burning out the variable speed resistor.
8. When the outside temperature is low and there are many drivers and passengers in the cab, the glass will be frosted, the control can be put in the defrosting position and the outdoor circulation position, and the motor can be placed in the first or second gear position so that the frost can be removed.
9. When there is no wind sand or dust outside, the circulation can be put outdoors to make the cab air fresh. If there is wind and dust or the weather is too cold, put the circulation into the indoor circulation to avoid wind and dust entering the cab.

In conclusion, industrial electric fan heaters are an excellent choice for heating large industrial spaces quickly and efficiently. When choosing an industrial electric fan heater, it's essential to consider the wattage rating, the size of the space, and the durability of the construction. With a suitable industrial electric fan heater, you can ensure that your workers are comfortable and productive all year round.
