Max. thermal output

The highest heating power produced by an industrial heater.

The maximum area that the unit can effectively heat directly depends on this parameter (see below). Even if it is not indicated in the specs, it can be approximately determined from the calculation that for heating 1 m² of a room with a standard ceiling height of 2.5 m and good thermal insulation will require 100 W of thermal power. If the ceiling height is significantly different, then the power required for heating can already be withdrawn from the volume of the room — every 2.5 cubic metres of volume will require the same 100 W (and the volume is found by multiplying the area by the height of the ceiling). There are also more complex formulas for the most accurate calculation, taking into account the degree of thermal insulation, the temperature difference between inside and outside the room, etc.; they can be found in special sources.

Note that in electric models (see "Power supply"), the maximum thermal power, in addition to all of the above, also determines the total power consumption of the unit: the power consumption (see below) cannot be less than the thermal output (usually, it is somewhat higher due to for the removal of part of the energy for the operation of the fan). In devices with a water circuit, the actual thermal output depends on the temperature of the coolant at the inlet and outlet. Therefore, in the characteristics, a certain standard value is usually indicated, and in t...he notes, it is specified for which temperatures it is relevant (for example, 90 ° / 70 °).

Max. heating area

A very conditional parameter that slightly characterizes the purpose by the size of the room. And depending on the height of the ceilings, the layout of the room and the equipment, the actual values ​​​​may differ significantly. Nevertheless, this item represents the maximum recommended area that the heat gun can effectively heat.

When determining the maximum area, usually, a universal formula is used that is valid for all heaters: 1 m² of floor space in a room with a standard ceiling height of 2.5 m requires 100 W of thermal power. Therefore, if the ceiling height differs markedly from this value, the actual heating area should be recalculated; for more details on scaling, see “Maximum thermal output".

Rated current

The current consumed by the heat gun during normal operation. This parameter is useful primarily for assessing the load on the mains that occurs during the operation of the unit and organizing the appropriate connection. In particular, the rated current of the fuse installed in the connection circuit cannot be lower than the total rated current of the connected load — otherwise, the power will be turned off. Heat guns (primarily electric, see "Power supply") are quite high consumption consumers in terms of current.

Power consumption

The power consumed by the electrical components of the industrial heater during operation.

This parameter allows, first of all, to assess the load on the power grid and the suitability of the available power for the normal operation of the unit. It is relevant for all types of modern industrial heaters (see "Power supply"). However, it is worth noting that in some electric models, the power consumption is indicated for the ventilation mode. In this mode, the heating element is not activated, and the power consumption is extremely low — a few tens of watts. In such cases, the total power can be estimated from the maximum thermal output (see above) — in electrical models, these parameters practically do not differ from each other.

Airflow

The maximum amount of air that an industrial heater can pass through itself in a certain time.

This parameter is associated with an increase in air temperature (see above): at constant power, higher performance usually corresponds to a smaller temperature difference. Accordingly, a more efficient industrial heater will heat the entire volume of the room faster, but the heating temperature will be lower. So, it is worth choosing according to this parameter, taking into account what is more important for you — a large temperature difference or a high heating rate.

Gas pressure

Gas pressure for which the gas industrial heater is designed (see "Power supply").

The pressure in the gas pipeline or at the outlet of the cylinder to which the unit is connected must correspond to this parameter as much as possible. If the pressure is too low, the gun may either not give out the required thermal output, or not start at all, and increased pressure is fraught with damage to the device and even injuries to others. Permissible deviations in working pressure for each model are different, this point should be clarified according to the manufacturer's official data.

Max. fuel consumption

Fuel consumption during operation of a gas or diesel (see "Power source") industrial heater at maximum power.

This parameter determines the efficiency of the unit; on the other hand, high power is inevitably associated with high consumption, therefore, only models with the same power source that do not have significant differences in power can be compared with each other in terms of high consumption. In addition, knowing the volume of the fuel tank (see above) or gas cylinder, this parameter can be used to calculate the time during which the heat gun can continuously work regardless of the selected power (for more details, see "Maximum operating time"). Note that this time is usually less than the maximum.

Features

Temperature control. The ability to change the heating temperature provided by the industrial heater. This function allows you to optimally adjust the operation of the device to the necessary conditions and heating intensity.

Thermostat. A thermostat is a device for maintaining the air temperature at the same level. The principle of operation of this device is as follows: when the required air temperature is reached, it automatically turns off the heating, and when it gets cold, it turns it on again until the air warms up sufficiently. The temperature of the thermostat operation, usually, is set by the operator of the heater.

Piezo ignition. The presence of a piezoelectric ignition system in the design of the industrial heater. In such systems, the spark necessary to ignite the fuel is generated by the operation of a piezoelectric generator, and its operation is based on the use of a special material that, when bent, generates an electric current. It means that no external power is required for ignition — the necessary energy is generated by the operator himself when the button is pressed. In addition, piezoelectric systems are considered very convenient for several other technical reasons. They are found mainly in gas industrial heaters (see "Power supply") because, for diesel fuel, such ignition is poorly suited.

Complete fuel combustion. This feature is found in gas and diesel models (see "Power supply"). It means that the fuel in the combustion chamber of the heater burns out completely, without forming soot and other by-products and practically without creating unpleasant odours. In addition, it has a positive effect on efficiency. This feature is especially important for diesel units because diesel and many types of liquid fuels are "dirtier" than gas and more prone to soot. Smokeless combustion facilitates the use of heaters in rooms where there are people — however, note that it does not cancel the requirements for good ventilation, since combustion products still need to be removed from the air.

— Fan mode. The ability to operate the heater in the ventilation-only mode, when the device circulates air but does not warm it up. The purpose of this function is obvious: situations when the room is already warm enough, or heating is not required for other reasons.

— Fuel level indicator. The presence in the design of a diesel heater of a sensor that signals the amount of fuel in the tank. The design and operation of this sensor may vary from model to model: in some devices, it constantly displays the remaining fuel; in others, it plays the role of an alarm and turns on only when the fuel level drops below a certain value. However, this feature makes it easier to monitor the condition of the unit and prevents troubles associated with unexpected emptying of the tank.

— Air filter. The presence of an air purification filter in the design of a diesel heater. One of the “weaknesses" of such units is the nozzles that supply the fuel-air mixture to the combustion chamber; contaminants that enter these nozzles clog them and can even disable them. The air purification filter prevents such troubles: it traps dust, sand and other mechanical impurities, ensuring stable operation and durability of the injectors.

Protection class (IP)

An indicator that determines the degree of protection of dangerous (moving and current-carrying) parts of an industrial heater from adverse effects, namely solid objects and water. The level of protection is usually indicated by a marking of the letters IP ("ingress protection")) and two numbers, the first of which indicates protection against the effects of solid objects, and the second — against the ingress of water.

For the first digit, each value corresponds to the following protection values:
1 — protection against objects with a diameter of more than 50 mm (large body surfaces)
2 — from objects with a diameter of more than 12.5 mm (fingers, etc.)
3 — from objects larger than 2.5 mm (most instruments)
4 — from objects more than 1 mm (almost all tools, most wires)
5 — dustproof (full protection against contact; dust can penetrate inside, but does not affect the operation of the device)
6 — dust tight (case with full protection against dust and contact).

For the second digit:
0 — completely unsuitable for contact with water, the device requires protection from moisture and is not suitable for rooms with high humidity.
1 — protection against vertically falling drops of water
2 — from water drops with a deviation of up to 15 ° from the vertical axis of the device
3 — from water drops with a deviation of up to 60 ° from the vertical axis of the device (rain)
4 — against splashes from any...direction 5 — against jets from any direction
6 — from sea waves or strong water jets
7 — the possibility of short-term immersion to a depth of 1 m (without the possibility of continuous operation in immersed mode)
8 — the possibility of long-term immersion to a depth of more than 1 m (with the possibility of continuous operation in immersed mode).

The protection class of industrial heaters, usually, is quite low, because the very principle of operation of these devices involves an abundance of holes and openings.
