Heat guns are great for heating non-residential buildings. However, often such premises do not have power supply. In such situations, an autonomous heat gun can help, able to function without being connected to electrical network.

Types of aggregates

Autonomous heat gun without electricity, it is most often represented by liquid fuel devices. They are able to work for various types liquid fuel: diesel fuel, kerosene or waste oil.

It should be noted that autonomous heat guns without electricity, operating on liquid fuel, can have the principle of direct or indirect heating. The former throw the products of fuel combustion directly into the heated room. Because the latter must have effective system ventilation.

Autonomous heat guns of indirect heating have a more advanced design, in which there is a discharge pipe for exhaust gases. As a result, such devices are quite suitable for rooms with people.

Benefits of independent type heaters

It should be noted that liquid fuel devices have safety systems, including:

Overheating protection;

A system that controls the flame of the burner, which allows the gun to turn off automatically when the flame goes out.

Autonomous heat guns without electricity also include gas heat guns. The devices capable of operating on bottled gas are distinguished by the greatest autonomy. After all, they can be moved indoors or transferred to another building. Such devices also have a burner, which, unlike liquid fuel devices, runs on gas.

As you can see, heat guns autonomous type perfect for rooms without power supply. They are safe, effective and quite economical.

To ensure targeted heating, heat guns are most often used. Their feature is high power in the supply of air masses of a certain temperature. This is due wide application of this equipment in the construction industry and industry. A properly selected diesel-fueled heat gun is capable of heating concrete, maintaining an optimal microclimate in the production room, and also protecting plants in the greenhouse from hypothermia in winter.

The principle of operation of heat guns

The organization of the working process in any heat gun provides for the possibility of activating a fan, which provides air supply. V this case this task is realized due to the energy generated in the combustion chamber of diesel fuel. The design of the unit provides a tank for pouring diesel fuel or kerosene. Through a special filter, the mixture enters the sump, and then the pump pumps it into the nozzle for further use. Usually, a fan is located at the rear of the equipment, which supplies cold air masses to the combustion chamber, distributing diesel from the nozzle in it. Ultimately, the fuel is burned, and already hot masses are sent to the target object. According to this scheme, the general principle of operation of a heat gun on diesel fuel is built, but there are some differences in the process, depending on design features one model or another. By at least, there are fundamental differences in the operation of two types of such installations - with direct and indirect heating. It is worth familiarizing yourself with these types of heat guns in more detail.

Types of heat guns

Models with direct heating are distinguished by the fact that during operation they release the combustion product directly into the operating area - this can be, for example, a production room or a construction site. Modifications with indirect heating provide for the removal of combustion products outside the boundary of the working object. Obviously, direct heating has serious limitations in terms of use. In particular, such equipment cannot be used in residential areas. In exchange for this inconvenience, the user gets better performance.

In turn, an indirect heating diesel heat gun can also be used in rooms where people are located. Its design includes a mechanism for removing combustion products, which is joined to the chimney channel through a special pipe. That is, in the process of work, heat flows get rid of burning, spreading around the room or workshop in a relatively pure form. True, the operation of such models requires organization ventilation system indoors as the unit will process oxygen.

Main characteristics of the equipment

Among the main technical and operational parameters of heat guns, it is worth noting the power, the volume of delivered air and fuel consumption. As for power, this indicator is in the middle corridor from 10 to 80 kW. For residential premises, installations with a power potential of 15-25 kW are usually purchased. In industry, more productive units with a capacity of about 200 kW are used. In order to ensure future savings, the volume of combustible mixture, due to which the heat will work. Fuel consumption varies on average from 1 to 6 l / h. The higher the power, the more gluttonous the heat generator. Depending on the area of ​​\u200b\u200bthe room, the volume of warm masses that the installation will distribute is also selected. This figure can be both 200 and 3000 m 3 / h. For a living room, an installation with an initial volume value will suffice, while production facilities, warehouses and construction sites are serviced by high-performance heat guns.

The designers have improved the strength characteristics of these parts, so there is practically no criticism regarding the reliability of the Jumbo 200 M installation. In addition to this, many emphasize the benefits of safety and limiting thermostats, which increase the safety of equipment operation.

How to choose the best option?

It is necessary to take into account not only the nature of the intended use, but also the dimensions and the need for availability. additional features. You can build on the power potential and performance indicators. This will help to determine the principle of operation of the gun - with or without the withdrawal of spent combustion products. In accordance with the dimensions of the room, the dimensions that a diesel-fuelled heat gun can have are determined. It is not difficult to install this unit with your own hands, but in the case of models that provide exhaust gases, it may be necessary to additionally equip the structure with pipes and chimney adapters. It will also not be superfluous to calculate in advance the need for electronic systems controls with heat gun control.

Most heat generators operate in intensive mode, which increases the importance of technical measures for their maintenance. The main concern of the user is to clean and replace the filters regularly. In particular, the air filter element, which filters out fibers and fluff, should be replaced every 500 hours of operation. As a rule, it changes at the end of each season. In order to avoid the need to run on diesel fuel in terms of power stuffing, you should regularly take care of the fan. In a contaminated state, it complicates the workflow, which increases the load on the generator. Therefore, the fan should be cleaned at least once a season.

Conclusion

In most cases, heat guns are massive structures, which at the same time have an impressive weight. Despite this, such equipment is quite practical in operation and performs its tasks without any problems. True, depending on the design, diesel-fueled heat guns can present special requirements to the place of use. This mainly applies to models with indirect heating, the operation of which is possible only in rooms with organized ventilation. But also do not forget about the specifics of the use of units that directly emit combustion products into environment. It is desirable to use such models outdoors or in production workshops where the presence harmful substances will not pose a risk.

Shop "Termomir" offers customers a wide range of heat guns. Sale of fan heaters is carried out on the official website wholesale and retail.

Heat guns (fan heaters) are a simple and compact type of heaters in a durable case, inside of which there is a heating element and fan.
Heat guns differ in: electric, diesel, gas and water; actively used in non-residential, household and industrial premises, on construction sites, in workshops, in garages, warehouses, pantries and cellars, for heating and drying various materials and surfaces, etc.

Electric heat guns (fan heaters) are popular electrical appliances for heating and drying non-residential premises of small and large areas. Such guns operate from a conventional electrical network, are compact in size and weight, are easy to move, equipped with overheating protection and control devices.
Household models up to 5 kW operate at 220 V, more powerful industrial fan heaters at 380 V.

Gas heaters - appliances for liquefied gas(on propane), providing additional heating and dehumidification of large non-residential premises due to increased power and productivity. Often gas guns used in warehouses, production halls, trade pavilions etc.

Diesel heat guns are powerful liquid fuel fan heaters for additional heating of large non-residential areas. Such liquid fuel guns are used exclusively in non-residential premises: at construction sites, in hangars, large warehouses, workshops, and other industrial facilities, since they affect the state of the atmosphere inside the premises.
In the range of these guns, there are thermal gas guns of direct and indirect heating. Direct fired diesel guns are characterized by the fact that during the operation of such a gun, combustion products enter directly into the room, so they quickly warm it up, but at the same time without fail constant ventilation is required. Diesel guns of indirect heating equipped with a chimney and all products of combustion are removed through it, and, nevertheless, such a gun is also recommended for use in non-residential premises with constant ventilation due to the combustion of oxygen during the operation of the fan heater.

Water heat guns (fan heaters on hot water) are economical and powerful water devices for heating and dehumidification various premises. Such water heat guns are particularly economical, energy consumption during their operation is minimal, and the efficiency and productivity of the air flow are very high. The installation of such heat fans is stationary, they are not so easy to move from place to place, because they are connected to the main hot water, but of all types of heat guns they are the most profitable, especially when working in large rooms. The proposed water guns are equipped not only with thermostats, but also modern management and many additional features and options for maximum convenience.

Modern thermal fans are equipped with thermostats (thermostats) and power adjustment, protection against overheating and tipping over, convenient and economical to use. Their merit is small size, free movement and easy installation.

A large assortment of heat guns is presented below on the page and in the menu of the site. If you find it difficult to make a choice, please contact our specialists for advice.

Rapid heating of the room is possible with the help of special thermal equipment. In addition to stationary devices, there are also mobile thermal stations. Their principle of operation is based on the creation of a powerful heat flow, which in a short time raises the temperature in the room to the required value. Such a need may arise during construction and repair work, to comply temperature regime in production.

The most popular type of such equipment are heat guns. Depending on the type of energy carrier, they can be gas, electric or diesel. The latter are the most popular because they can work offline. But when a diesel engine is running, exhaust gases and combustion products are released. In order to protect people in the room, a special type of diesel gun with indirect heating was developed.

Structurally, it is a movable platform, in the lower part of which there is a fuel tank and a supply system to the upper cone chamber.

With the help of a pump, the fuel is metered into the combustion chamber, which is located in the main cone according to the "pipe in pipe" type. The small chamber is completely isolated from the external environment, with the exception of the carbon monoxide exhaust system. In the process of burning diesel fuel, the walls of the inner chamber heat up. At the same time, the fan starts to work, which creates an air flow passing over the surface of the inner chamber. In the process of its movement, heat from the walls is transferred to the moving air and further into the premises.

The advantages of such an operational heating system:

1. High rate of temperature rise.
2. Long operating time without refueling - up to 10 hours.
3. Independence from the presence of the main heat carriers - gas, electrical network with a large power reserve.
4. Mobility.
5. Possibility of installation.

The main characteristics for these heating devices are:

• Thermal power - 21 to 220 kW.
• Tank volume and fuel consumption in various operating modes.
• The area of ​​the heated room. This parameter is given without taking into account the height of the ceilings and the area of ​​window structures.
• The volume of air flow for 1 time.

Despite their narrow focus, there are many manufacturers on the market that offer different types heat guns running on diesel fuel.

The most powerful of them are productive heat guns. They are designed for heating large rooms and are characterized by high power. The most powerful unit is a diesel-fueled heat gun. Working on diesel fuel, it generates enough heat to heat quite large volumes.

In this review, we will look at:

• Scope of diesel heat guns;
• Varieties of heat guns on diesel fuel;
• Their advantages and disadvantages.

At the very end, we will talk about the most popular models on sale.

The principle of operation and scope of diesel heaters

A diesel fuel heat gun is a fairly versatile unit. But not only for heating residential premises. Such units are used for heating warehouses, hangars with machinery, facilities under construction, large garages and greenhouses. The principle of operation of heat guns is very simple - diesel fuel burns inside them, and the resulting heat is pumped by a powerful fan into the heated space.

Despite the use of diesel fuel, this type of heat gun cannot be called autonomous. Electricity is still required to operate the burner and blow hot air.

An interesting feature of any diesel-fueled heat guns is that they are volatile - they need electricity to operate. Low-power models can operate on 12 volts (or 24), but the vast majority require connection to a 220 volt network. Electricity here is necessary for the operation of the burner and forcing hot air into the heated rooms (for fan rotation).

The burner in any diesel gun works as follows - it sprays diesel fuel and at the same time provides air supply. The resulting fuel-air mixture ignites, creating a steadily burning flame. The heat generated in the liquid fuel heat gun is sent to the room - the powerful fan.

Heat guns on diesel fuel are necessary:

• For heating warehouse premises - they generate a large number of hot air, allowing you to do without full heating;
• As backup sources heat for heating any objects in the event of frosts that are uncharacteristic for the area;
• For heating construction sites, when there is still no heating here;
• For heating hangars in which people work and equipment is stored;
• For mounting stretch ceilings- required here powerful source heat;
• For heating greenhouses where any crops are grown.

At the same time, a thermal diesel gun is not suitable for heating residential premises. There are two reasons for this - too high productivity and the need to remove combustion products.

Varieties of diesel heaters

Heat guns running on diesel fuel are represented by two large categories - these are direct and indirect heating devices. Let's see how the presented varieties differ from each other.

Heat guns of direct heating

Direct heating diesel gun is the simplest source of thermal energy. It is equipped with a fully open combustion chamber. Its heart is a pump with a nozzle that provides the generation of a torch. Behind him is a powerful fan. The generated heat, together with the products of combustion, is sent to a heated room. That is, there is no separate chimney here, which is a big minus.

A direct heating heat gun is harmful to human health, therefore its operation in an unventilated room is prohibited (despite the almost complete combustion of diesel fuel). Yes, and where there is good ventilation, people will constantly be haunted by the smell of burning - there is no getting away from this. These units are most commonly used in open areas where there is fresh air.

There are craftsmen who manage to convert direct-type guns into indirect-type units, which will be discussed later - they are safer.

Heat guns of indirect heating

Being near a direct-fired diesel heat gun is like sniffing the smoke from a truck's exhaust pipe. Prolonged exposure to a heated room can lead to severe headaches and poisoning. Therefore, such units are used relatively rarely. But they came up with a great alternative.

The diesel heat gun of indirect heating is a more perfect and advanced device. In some ways, it resembles a liquid fuel heating boiler. Only it does not heat the coolant, but the air. The basis of such a heat gun is the same nozzle - it is placed in a closed combustion chamber equipped with a system for removing combustion products (in other words, a chimney). The rest of the design is the same.

Due to the removal of combustion products to the outside, such units can be used to heat unventilated rooms. The forced air in these guns does not come into contact with the burning torch - it seems to blow over the combustion chamber. As for burning and soot, they go to the connected chimney and do not enter the premises. Thanks to this, indirectly heated diesel fuel heat guns can be used in almost any conditions.

Despite the presence of the removal of combustion products to the outside, for the operation of units of indirect (indirect) heating, at least some kind of ventilation is still needed - oxygen for the burner is taken directly from the room.

Advantages and disadvantages

Let's see what are the advantages and disadvantages of diesel fuel heat guns. They have a lot of advantages:

• Ease of maintenance - there is no complicated diesel used in automotive equipment. The heart of these units is a simple diesel heater in the form of a nozzle with a pump;
• A heat gun can have great power - there are samples with a power of 10, 20 or 30 kW on sale, as well as monstrous units with a power of up to 150-200 kW;
• The possibility of heating large rooms in the most short time- thanks to the use of efficient fans, diesel fuel heat guns are characterized by high performance;
• Profitability - in comparison with electric units, even long-term operation of a diesel heat gun will not lead to gigantic costs.

There are also disadvantages:

• Diesel heat guns of direct heating are unsafe for humans - they release toxic components into the air resulting from the combustion of diesel fuel;
• Energy dependence - these units cannot work without a source of electricity;
• High cost - diesel heat guns are appliances industrial use what affects their price;
• The smell of diesel fuel - with prolonged use, the smell of diesel fuel may spread in the room.

Cons are not the most serious, so they can be neglected (with the exception of the first paragraph)

Popular Models

If you want to buy a diesel heat gun, then you will need information about the most popular and popular models. Let's consider them in more detail and talk about their technical characteristics.
