How to properly connect a heat gun

The gas gun is connected according to the following rules: Connect the gun to a cylinder or other gas source.

For example, the unit does not always have a relay for temperature control. These devices belong to the professional category because they cannot be used in domestic premises.

This is especially true for transporting a gun in autumn or winter. Electric heat guns, reviews of which indicate the thoughtfulness of their design, differ from gasoline and diesel ones in that they provide absolute safety during operation. AND STILL SHE BANGED! Electric Gun (Continued)

And this depends on the planned power of your device for household devices and network B, it is advisable not to exceed 5 kW. Devices with higher power are equipped with heating elements, due to which the efficiency of the device significantly increases along with safety. Please comment on the material we present and post photos on the topic. The upper part must be made of thick metal.

Using the built-in thermostat, it is possible to maintain a certain temperature of the heated air at the proper level.

Never install the gun near electrical outlets, cabinets or under wooden shelves.

The annoying noise from the operation of the impeller can be reduced if relatively quiet car fans are used for the design. The power of industrial guns varies from 2 to 45 kW, and the number of heating elements in them can reach up to 15 pieces. Let's consider how an electric unit works.

ELECTRIC GUN Not Gaussian!

What to consider when choosing

The main selection criterion is the thermal power of the device.
A correctly selected parameter will not only help to optimally heat the room, rationally using electrical energy, but will also help maintain the functionality of the gun for a long time. Thermal electric guns can be calculated using the formula:

Р=VхТхК, kW

where V is the volume of the room; T – temperature difference between outside and inside the room; K – coefficient of thermal insulation of walls.

K=3...4 – walls made of boards or steel corrugated sheets;
K=2...2.9 – walls made of brick in one layer, roof without insulation, simple windows;
K=1...1.9 – standard wall, roof and insulated windows;
K=0.6...0.9 – walls made of two layers of brick, there is additional thermal insulation, high-quality plastic windows, additional thermal insulation of the roof.

The final result calculated using this formula is measured in kcal/hour.

To convert to watts, you need to multiply the resulting number by 1.16.

For rooms with an area of 5-6 m², 0.5 kW devices are suitable.

For every 2 additional m² we add 0.25 kW to 0.5.

In this way, the required power of the heat gun is determined.

The market for electric heat guns offers mobile and stationary options, so before purchasing, you should decide which one is more appropriate in your case.

If you intend to use the device constantly in the same room, for example, for a summer house, then you can purchase a stationary gun.

If you plan to use it as an additional heat source or the frequency of use is not too high, then it is wiser to take a mobile variety.

Pay attention to the design of the heating element. In rooms where people are often present, you should choose models with a closed thermoelement

In rooms where people are often present, you should choose models with a closed thermoelement.

Otherwise, human health may be negatively affected by the combustion products of debris particles that end up on the heating element.

A wide range of products allows you to choose the housing option that best fits into the environment.

You should also pay attention to the material from which it is made - choose the one that is most resistant to heat.

The noise level produced by the gun is of no small importance when installing it in rooms with people. To avoid discomfort, we recommend models with a noise level not exceeding 40 dB

To avoid discomfort, models with a noise level not exceeding 40 dB are recommended.

If the determining factor is the power of the device, for example installed on a construction site, then in this case the effectiveness will be much more important than the sound impact.

And, of course, an important factor is the cost of an electric heat gun.

It would be irrational to buy an expensive, powerful device for a ten-meter room.

And for large areas, such as construction sites, warehouses, and industrial premises, powerful industrial electric heat guns are needed, the cost of which can be 30-40 thousand rubles.

Taking into account the combination of all these factors, you can choose the most optimal option for an electric heat gun

Features of use

Electrical diagram of a heat gun Rules for using a direct heating Master diesel heat gun Master b diesel heat guns are directly heated heaters that supply thermal air along with combustion products.

So, if the device’s power does not exceed 6 kW, it can be connected to a single-phase network. Connect the power cord, cable from the heating elements and fan to the control panel. After checking the insulation of all connections, you can test run the device.

To make an electric gun with your own hands, you will need: a steel body; frame where the structure will be located; electric fan; wires for connecting the device to the electrical network; switch The motor with fan is mounted on the rear grille of the heat gun behind the heating elements.

At the moment, a wide range of domestic and foreign products are on sale, and the prices are quite reasonable, for example, for products. And not every network will support such a device.

The heat gun provides targeted heat supply and can be used in warehouses, cottages, shops, shopping centers, offices and hangars. Such guns are used either in open areas or in rooms with a good supply and exhaust ventilation system. After completing the assembly, perform a test run of the heater. The heating elements in this model, 6 of them, look like this: Depending on the selected mode, either three heaters or all six are used.

Hot air is not blown out of the unit, but is processed in a heat exchanger, due to which the temperature inside the room rapidly rises. It is not recommended to direct high-power heat flow to synthetic materials, which, when heated, release caustic and toxic substances. Electromechanical injection is carried out by installing a fuel pump and an air blower. Connecting a diesel gun Check that there is fuel in the tank, check its level, and securely close the fuel tank opening. That is, the heating element is responsible for the heating temperature, and the fan is responsible for the quality of distribution.

Such an assembled system will make electric heating fully automatic and economical, so we recommend using it. To avoid various kinds of problems associated with the operation of the heat gun, you need to adhere to certain rules. The thermoelement 7 heats up and facilitates the passage of gas into the fire extinguishing chamber 2. This is especially true for transporting the gun in autumn or winter.

Hot air masses, together with combustion products, rush into the heated space. Conclusions and useful video on the topic What do you need to know about the electric gun? Some heat guns are connected to a volt network. HOW CURRENT FLOWS IN THE CIRCUIT - Read Electrical Diagrams Part 1

Communications liner

It is necessary to take into account that the heating main must provide the required cross-section (the diameter must meet the technical requirements). And yet, the necessary flow of coolant through the fan heater must be ensured. If the diameter of the pipes and the temperature of the coolant are sufficient, but the speed of movement (flow) is very weak, this will negatively affect the thermal power of the device!

Also, think about how to supply power and control circuits. Calculate the required distances to purchase the required footage of electrical wire.

And one moment. Make sure that the wall (or ceiling) on which the fan heater will be mounted is of sufficient strength to withstand the load.

Characteristics of electric heat gun

This powerful device simultaneously performs several functions: it heats the room, ventilates the air and dries it. This is probably why the electric heat gun is so popular and in demand.

It is used not only on construction sites for heating and drying walls, but also in any garage when repairing a car, in the basement, in warehouses, in shops and country houses. Rectangular guns attach well to the wall, while cylindrical guns are ideal for spot heating.

The principle of its operation is quite simple: with the help of a powerful fan, air is driven through the heating element and distributed throughout the room. The air in the room heats up very quickly, so this type of air heater is most often used in winter.

Using an electric heat gun is convenient because you do not need to coordinate its installation with numerous regulatory authorities. These devices are reliable and durable.

Those devices that operate on a voltage of 380 V have a power of up to 25 kW. The temperature is adjusted using step-by-step starting, and there are all the necessary overheating protection functions. The weight of these devices reaches 30 kg. High-quality devices from well-known manufacturers are equipped with heating elements that do not burn oxygen.

Installation and repair of a heat gun

My garage needs heating. There is no stove, but I have a 380, which I want to hang a gun on. I bought the gun in non-working condition. Under restoration. 3 pieces of tensile wires on the gun are connected according to the “star” type. Connection diagram 2+1 6/9 kW. Each heater is 3 kW. Without using zero. The control is powered from one of the phases and zero. There is a starter. The scheme is like this. The shadow phases are supplied directly to the starter. The control phase comes to the fan button. When it is turned on, the extra-tilator is turned on and the phase goes on to the button for turning on the shadows 2pcs. When pressed, the starter clicks and releases current to 2 tenons and the switch button for the third tenna. When the button is turned on, current flows through it to the ten.

Tips for choosing an electric heat gun

When buying any device, everyone wants it to work not only efficiently, but also for as long as possible. Therefore, we choose electric heat guns only from well-known manufacturers.

The body of the device must be made of metal; if a scattering grille is installed, it must also be metal. This is guaranteed to protect the device from deformation due to temperature changes and in the event of a power outage, when the fan stops and the heating elements do not have time to cool down, nothing will happen to the heat gun.

An electric heat gun must have a stable, durable design.

You need to choose a device whose body is marked: 24/2 or 24/1. This means that this heat gun can work around the clock, with a break in operation of 1 or 2 hours.

Pay attention to the presence of overheating protection, a heating level regulator, and an air flow switch (switching fan speed). A huge advantage is the presence of a service center in your area

A huge advantage is the presence of a service center in your area.

Types of heating elements

Diagram of operation of a diesel heat gun.

An electric heat gun can have two types of heating elements located in it: a heating element in the form of a spiral or a heating element.

When using heating elements, the device heats up more slowly and the heating temperature is not as high as when using a spiral. But such a heat gun is much safer and more durable than a spiral one. This happens because dust and debris do not collect on the heating elements, so accidental fires are minimized. It is the choice of a heat gun using heating elements that is recommended for use in residential premises.

An electric heat gun using a spiral heating element is characterized by almost instantaneous heating, the atmosphere in the room quickly becomes comfortable for further work, but at the same time some of the oxygen is burned. Therefore, it is not recommended to use it in residential enclosed spaces; it is better to use such a device in a garage, outbuildings, etc.

These air heaters can operate at voltages of 220 V and 380 V.

general description

The diagram for connecting the fan heater to the Volt network looks like this: If the power of the product is over 6 kW, you cannot do without three-phase electrical wiring. Connect the plug to the voltage, switch the device to operating mode, set the desired heat supply.

For example, the Ballu electric heat gun is distinguished by the presence of heating elements of an improved design, which significantly increases their working life. The fan is one of the important parts of the design.

Afterwards, the fuel pump is attached, and a metal pipe is connected to the tank, with the help of which the fuel is supplied first to the fuel filter, and then to the injector.

Small size and weight make devices of this type transportable and mobile. Any device in this category is prone to consuming large amounts of electricity.

You can also choose a regular metal tank, which must be covered with a thermal insulation layer. The power of the heating element should be stamped on its body or written down in the accompanying documentation, but if it is an old device, you can measure its resistance with a multimeter and determine the power using the above formula. In addition to the three main elements of the housing, the motor and the heating element, for operation you will need a three-core cable, bolts, safety automatic circuit breakers and residual current devices (RCDs) that disconnect the network in a dangerous situation.

Device design The circuit of an electric heat gun assumes the presence of very specific components, but there are also optional components. With proper assembly of the electrical circuit, the risk of spontaneous combustion for such guns is minimal.

It is important to remember that it is almost impossible to heat a plank shed, a large hangar or an iron garage. DIY pneumatic machine
