Diesel gun: testimonials and selection criteria. Diesel indirect heating gun: specifications

Diesel thermal gun is an ideal option for the rapid heating of a construction site, agricultural, storage or industrial premises. Since its work is carried out on diesel fuel, it spends only electric power for the operation of the automation and the fan. As the main advantages of such a technological solution, one can call a comparatively high thermal power with rather small dimensions. The design of the heat gun contains such basic elements: a burner located in the combustion chamber, a fan engaged in air injection, a fuel tank.

Principle of operation

There are two types of aggregates of this category: direct and indirect heating. In the first variant, all exhaust, that is, spent gases, are inside the heated room. It is not recommended to use such devices in residential buildings. Diesel indirect heating gun implies that the withdrawal of residues takes place on the street through the installed chimney. The room is exceptionally warm clean air. However, an indispensable condition for the operation of such guns is the availability of high-quality ventilation, since oxygen in the room is consumed during its operation.

Varieties

An indirectly heated indirect diesel can have one of two design schemes. The first option is the device, in the case of which the elements of the burner device are built. The operation of a single axial fan ensures the supply of air for heating, as well as the oxygen required for the combustion process. A diesel gun of this type belongs to the category of semi-professional equipment. Its distinguishing feature is sensitivity to fuel quality and voltage fluctuations in the supply network. Since only one fan is used for two air paths, any resistance in each of them can affect the combustion and operation of the device as a whole. In another scheme, there is a pair of fans: one provides clean air and the other a combustion process. Such a device is characterized by professional instruments, whose power starts from 50 kW. They are characterized by a long service life and maximum reliability.

Technical characteristics of indirect heated diesel guns

Equipment of this type usually has a higher power compared to direct heating analogues. Any diesel gun is made of high-quality durable stainless steel, has a thermal insulating casing of the electric motor, and also features a resistant outer coating.

The devices of indirect heating are oriented to large rooms, characterized by high-quality air circulation. This type of device is capable of providing space heating of up to 2200 square meters. In particular, the Master BV 690 E diesel gun differs in this way. The approximate fuel consumption of such units varies within the limits of 1.44-18.5 l / h. At the moment the main manufacturers of these devices are such companies as Master, BIEMMEDUE, Patriot Power.

Direct heating

Guns that work on this principle are designed for use in rooms with an area of no more than 500 square meters. In terms of operation, this type of device is as simple as possible. The output power can be 10-44 kW. Depending on the power, the weight of the units varies between 19-30 kilograms. The diesel direct-burning gun has a fuel tank, the volume of which depends on the dimensions of the device and can be 15-45 liters. The fuel consumption is 0.86-1.5 liters per hour. The fan operates from an electrical network with a voltage of 220 or 400 volts. This type of diesel guns is produced by such companies as Master, Resanta, as well as by Latvian and American companies.

Advantages of heat guns

The equipment working on diesel fuel has a whole complex of advantages. Since the device does not require binding to gas or electricity, it is distinguished by its autonomy and mobility provided by special wheels. With their help, the device can be moved to any convenient place. Due to the use of a diesel engine, high efficiency and productivity of the equipment is achieved.

Simplicity in operation and absolute safety are achieved due to the presence of a gas cleaning system, a thermostat protecting from overheating, a housing that is completely isolated from heating elements, and a stabilization system for the flame.

Diesel gun, the price of which is from 40 thousand rubles and above, is intended for heating of industrial premises, so do not choose this device if you need to heat a house or apartment. As the main competitor of the gun in terms of heating large rooms can be called only one unit - a solid fuel boiler. However, only the gun is capable of heating a truly dimensional room, and also provide ventilation and air circulation.

The difficulties that you can face when choosing

Thermal performance of the device should be selected depending on the total thermal power required to heat the room and ensure proper flow of technological processes. The required heat output is the estimated value depending on the average value of the winter temperature outside, the required temperature inside, and also on the sum of the available heat losses. The latter parameter depends on the material and thickness of the walls, floors, floors, the size of the gates and windows, the efficiency of the supply and exhaust ventilation. These data can be determined from the design documentation of the building, for which a diesel gun will be used as a heater.

The heater can be installed indoors or outdoors. The second option assumes the obligatory organization of the supply of already heated air to the heated object. Most models of diesel guns can be used in combination with air distributors and ducts.

Heating process

The speed at which the diesel gun warms up the room to the desired temperature depends on the flow of hot air. The more the heater can pass through itself, the sooner the heat will be spread over the room. But here it is important to understand that it is impossible to increase the flow without increasing the capacity of the heating device, and this entails an increase in fuel consumption.

Room warm-up speed

The diesel gun has one very important characteristic - the temperature difference between the taken and warmed air. This parameter is directly dependent on the performance of the device by air, efficiency and thermal power. The temperature of the intake air is usually irrelevant. For most devices of indirect heating, the temperature difference is 50-70 degrees Celsius, and for the direct one - 300-400 degrees.

Quite often the cannon for diesel heating is used to maintain a certain temperature level in the room. This stability is achieved by installing controllers or temperature controllers that are connected to the control system. When using the equipment in low-temperature conditions, it is required to provide fuel heating 10 degrees above the cloud point. Therefore, it is recommended to store diesel fuel in a warm room, and also to use a special fuel heater.

If it is necessary to move the diesel gun frequently, the right choice will be the purchase of a mobile model with a set of wheels, as well as special devices for moving by means of a crane.

The subtleties of the choice of a diesel gun

In the selection process, you must take into account the required performance of warm air for a particular room. The cost of the equipment is directly affected by the parameters of the device itself. If you select diesel guns for heating rooms, then you should take into account the power, dimensions, the absence of a chimney or its presence, the air temperature at the outlet, as well as other less important points.

It should be understood that a high level of productivity in combination with the maximum efficiency can only be obtained from a gun with direct heating. They should be installed where there is room for airing the room, as well as with a high probability that people will not be there. For open rooms, the indirect heat cannon is well suited, since it is characterized by high power and demand for a large air supply, which is sufficient in open air conditions. If you do not want to worry about turning off the device in winter, you must choose a model with a heated filter element. In this case, even low-quality fuel can be used.

Equipment with the eyes of a consumer: a diesel gun

Feedback about this device speaks in favor of the fact that this is the optimal solution for production and warehouse premises where it is required not only to quickly warm up the whole volume of air, but also to maintain the temperature at the proper level. This equipment shows itself well not only in terms of high performance, but also quite good fuel economy. It is important to understand that it is the cannon for diesel heating that can create the optimal temperature level in the dimensional room for the shortest period of time.
