Usually diesel heat guns are purchased when electric or gas heat guns are not suitable for some reason.

The maximum power of the guns reaches 200 kW, which is a great indicator. They can be used in large industrial enterprises. However, these models also have a number of disadvantages. They are quite expensive and also have a high fuel consumption. There is also an important requirement for good ventilation because the exhaust from these devices is powerful.

When choosing a device, you need to pay attention to several nuances:

1. heating type. Indirect diesel guns are very similar to gas installations. Fuel is fed into the nozzle and burned in the chamber. Air is blown into the room, warming it. Only in this case the chamber is closed, which increases the efficiency of the device. But its cost is almost 2 times higher than that of gas models.
2. Fuel is being used. Most heat guns run on diesel fuel and kerosene. But there are devices that require only a certain type of fuel. When using diesel fuel, more harmful substances are emitted into the atmosphere.
3. The heating power indicates how much heat can be obtained from the gun. The higher this value, the faster it will be possible to bring the temperature to the desired value. This indicator also depends on what area can be heated.
4. The hot air characteristics give an indication of how much hot air passes through the unit.
5. Possibility to adjust the temperature. That is, when a certain value is reached, the device turns off. For this, a thermostat is installed on it.
6. Power consumption. This parameter is relevant for understanding how much electricity will be spent when using the installation.
7. Fuel consumption and tank capacity.
