The device and features of the operation of heat guns on the water

With the onset of cold weather there is a need to heat the room without stationary heating. Due to poor heat and water insulation in apartments, warehouses, business centers and industrial facilities, the level of humidity increases. Low temperature can spoil a thermophilic item, which is located in a trade or exhibition hall. To dry the foundation and walls of the building, to maintain a certain temperature in the room, mobile devices are used, for example, heat water cannons. Because of their design, they have high heat transfer and spend a minimal amount of energy.

General characteristics of the device

The water heat gun is a heavy-duty fan heater that heats the space with air heated by hot water from the central heating system.

The device as a heating element uses heat exchanger with heated fluid. The shell of the fan heater is made of stainless steel, covered with high-quality polymer coating, the degree of protection of the housing - IP44. The unit consists of the following elements:

• heating element;
• high strength case;
• non-separable air heater assembly, made of copper pipes with inserted aluminum plates;
• an axial fan that creates a directed stream of air through the heating module of the device;
• filter;
• mounting bracket;
• drain pipes.

Heat guns on the water are fixed on the wall in a horizontal, vertical position or at a slight angle with the help of a fixing bracket.

Principle of operation

First, cold air is drawn in through the rear grill from the room to the heat exchanger. After warming up in the air heater, it comes back through the pivoting shutters or the protective-decorative mesh.On the supply line installed three and two-way cranes: they regulate the speed of the fan and affect the intensity of the heating device.

Thanks to the axial heat fan, the required volume of air flow is ensured for the proper functioning of the system. The greater the number of edges of the outer surface, the higher the heat transfer. The fan heater maintains the desired temperature in the room. When overheating, the device automatically turns off; if the air is cooled, it turns on.

Features of operation

Modern water heat guns with proper operation can last for several decades. To do this, use our recommendations:

• to avoid internal corrosion of the fan heater, when the appliance is idle, drain the water;
• in the room where the heat gun is installed, the air temperature should not be below -10⁰WITH;
• Do not use a fan heater if there are acids, alkalis, resins, technical fibers in the air - these substances are aggressive to the material of the device;
• relative humidity of the room should not exceed 80%;
• watch the level of dust and solid impurities - it should not exceed the limit value of 10 mg / m³;
• do not use the device without grounding;
• to avoid defrosting the stove when the water supply is shut off in winter, drain the coolant fluid;
• regularly wipe the dust on the device;
• Once every 3-4 years, rinse the fan heater, removing it from the wall.

Note! If the heat gun was transported or stored at low temperatures, the device can be switched on in a network 2 hours after being in the building.

The use of fan heaters

Water heat gun is used in those areas where there is a central heating system. Here are some of them:

• warehouses;
• production workshops;
• closed sports facilities;
• construction sites;
• supermarkets;
• greenhouse;
• offices in business centers;
• shopping pavilion;
• car repair shops;
• restaurants, canteens.

The equipment is installed around the perimeter of the room and connected to thermostat sensors. When the air temperature drops to the set value, the device turns on and begins to generate heat.Mobile design allows you to effectively heat up industrial areas, significantly saving on electricity.

Heat gun control

To control and control the operation of the fan heater, special electronic devices are used. Remote control - a device with which the remote control of a water gun. The device is included in the package and is mounted on the wall.

The device has slider switches and several touch buttons. The degree of protection of the casing of the device is IP20. If there is mixing unitThe remote control serves to regulate performance and heat output. One device controls only the same fan heaters.

Note! The control panel is configured at the factory. You can make the connection yourself by reading the manufacturer's instructions.

Features additional components

1. Thermostat
   The device opens the valve and turns on the fan heater when the temperature in the room is lower than necessary. The device has a high degree of protection: IP30. Weight is about 200 grams.

2. Controller
   The device controls the operation of the heat gun on the water in automatic mode with the possibility of programming during the week. One controller can control from 1 to 8 fan heaters. To control the speed of the device will need to connect to each device. The device has a built-in temperature measurement sensor.

3. Speed ​​controller
   Fan speed can be adjusted using a transformer regulator. The device is intended for only one heat gun. In total, you can choose about 5 speeds. Technique attached to the wall. It has a high level of protection: IP30.
4. temperature sensor
   The device allows you to install the controller in any room.

Power calculation

Water cannons consume 0.1-0.5 kW of power with an output parameter for heating of 10-60 kW. Knowing the area of ​​the room, you can calculate the performance of the fan heater. To do this, you can use the table:

The table is easy to find the desired parameter. If the room has an area of ​​100 m², the unit is selected with a capacity of 100-130 kW.

Advantages of a water fan heater

The advantages of space heating with a water gun include:

• small sizes;
• low temperature of the housing;
• thanks to the thermostat, the water gun automatically regulates the temperature of the air in the building;
• noiselessness of the device;
• high enclosure protection - IP44;
• the case and components are made of high quality materials;
• high efficiency - about 95%;
• fast heating and drying of the room;
• the ability to work with or without heating;
• availability of remote control;
• easy access to internal nodes;
• possibility of mounting on the wall for even heat distribution;
• the intake grille protects the device from the ingress of foreign objects;
• economical power consumption;
• long service life.

Main selection criteria

To make the water gun maximize its functionality, when choosing a device, pay attention to the following parameters:

• availability of mixing unit as an additional option;
• noise level - the more power, the higher this indicator;
• dimensions;
• device design;
• power - from this criterion will depend on the efficiency of drying and heating of the room;
• installation method.
