An industrial heater blower, also known as an industrial heater fan, an electric fan heater or an industrial fan heater, is a device that provides hot air to increase the ambient temperatures. An industrial heater blower is especially used in industrial environments and have a variety of usage, such as drying the products, melting the lubricating oils before applying to the machines, welding, or shrinking operations.
During winter, the air that blows through the atmosphere becomes cold, and the outdoor temperatures would decrease, and further cause the indoor temperatures lower down. Therefore, many people would rely on the domestic heaters to increase the temperatures indoors. While domestic heaters refer to a small area and wide range of heating, so the heats would not be equally distributed. However, for industrial usage, the range of the heating area can be either narrow or wide, from delivering hot air to a small piece of product to transferring it to the whole space. Industrial heater blowers offer more hot air with higher voltages than the domestic heaters.
● Electric input
The labelled capacity that you can see on an industrial heater blower would show you how many kilowatts it offers. Therefore, we can understand that the input of the hot air is transferred through electric input. This is what you need to take into serious consideration, because the electrical power an industrial heater blower offers make it whether useful or effective enough or not in the space it is placed.
Thus, before deciding which industrial heater blower you are going to buy, think about where it will be set first. For industrial usage, the amount of heat should be large-scale, whether it is distributed by what kind of heating system. But for an industrial heater blower, you should choose the one with the largest amount of electric power that you need. While it is certain that industrial heater blowers with large amount of electric power would be heavy duty and take up quite a bit more of space than some heating power that is emphasized with its portability.
● Heat output
As far as we know, an industrial heater blower is operated through the process that electric power transfers heat, and the hot air would be blown out to accommodate to different industrial usage. With some industrial heaters, the kilowatts from the electricity would be equal to the heat output, while although we may pursue the same thing in industrial heater blowers, actually, the situation is not the same.
The heat capacity we see in an industrial heater blower is actually the capacity of electric power input. When the electric power input is expressed by the heat output, the heat capacity would become slightly lower than how much the electricity provides. This may vary in the prices of the industrial heater blowers. the variation of the input and output would be bigger in some cheaper models. For example, 2.5kw electricity in and 1.8 kw heat out.
In the process of deciding which industrial heater blower to buy, the thermal performance of the building fabric is one of the important factors. Thermal performance is measured in terms of heat loss, which is usually expressed as a as a U-value. U-value, also known as thermal transmittance, is the rate of heat transferring through a structure, divided by the variation in temperature across that structure. The values can be differentiated into well insulated, moderately insulated, poorly insulated, and non-insulated. The better insulated the structure is, the lower the U-value will be. The U-value may decide how well the industrial heater blower works within a space.
● Thermostat control
Most industrial heater blowers would provide the function of thermostat control, since the ambient temperatures would be heated up through the operation of industrial heater blowers. Once the air is heated at too high of temperature, it may cause danger. Therefore, the thermostat control offers the protection in order to prevent the thermal from being overload. Some of the industrial heater blowers allow you to simply switch the heat source on and off, while others are equipped with thermostat control knob which offer stepless control of the heat settings.
Generally speaking, according to the construction of an industrial heater blower, the transferring of hot air is from electric input and heat output. Digging into the method of how an industrial blower works, it is from the principle of convection. Convection occurs when heat is transferred due to the motion of a fluid. There are two forms of convection, free convection and forced convection. Among them, the industrial heater blower is the application of force convection, which utilizes external force, blower or fan, to accelerate the flow of heat output and distribute the heat to the atmosphere. This is how an industrial heater blower works.
