Electrode Boiler - what is it and how to set their own hands Bashny.Net

Domestic boilers were supplemented with new models - the electrode boilers Galan, differing obvious advantage. Unlike other heating devices, the electrode boiler does not need to agree on the setting on the current "rules". What is the model of a new boiler, and what conditions exist for his autographic connection?

Boilers Galan, operating principles, specifications and design
Electrode heating boiler is a construction of heaters equipped with materials from the European manufacturer. Remember, this stainless steel grade AISI 316L and nichrome with high load capacity to withstand long operating cycle.




The principle of operation of the electrode boiler Galan consists of passing an electric current (electrolysis) through a special ice-free coolant.



Electrolysis and transfer electrodes heat the heated state is carried out at a constant current. The compact design of heating units feature small dimensions and weight of the boiler assembly. Coolant heating of the electrode system is antifreeze.



specifications
electrode boilers The main technical characteristics of the electrode boiler is power.

The range of electrode boilers hearth presented models, Geyser and Volcano.

The smallest boiler is a series of focus, which has a small power consumption (from 2 to 6 kW) intended for heating an area of ​​120, 230 and 280 cubic meters



For example, the electrode boiler Galan hearth 3 has the following characteristics:

Dimensions: length 275 mm, 35 mm, the device weighs less than 1 kg
. 3 kW allows to heat a room of 120 m3 area.
Models Geyser average performance have increased capacity - 9 and 15 kW with the possibility of heating the room, and an area of ​​340 550 m3. Overall dimensions are 360 ​​and 410 mm, 130 mm and weighs 5 kg.



The most powerful are the VOLCANO models with a capacity of 25, 36 and 50 kW and are designed for space heating from 830 to 1650 m3.

Linear electrode boiler efficiency can reach 96-98%. In relation to traditional heating coils, an electrode boiler efficiency up to 50% due to a direct method of heating the coolant.



The first thing that catches your eye at the sight of electrode boilers is an unusual design. Instead, surround the boiler and the pot-bellied long cylindrical structure with two threaded flanges, indicated by arrows of different colors (blue and inbound leaving red). Metal casing of the boiler may have a diameter of 40 to 100 mm length 310 - 350 mm.konstruktsiya electrode boilers



In the electrolysis process and on heating the coolant in the boiler rises to the internal pressure 2Atm. The heated water is forced upwards, providing the circulation pump functions. In addition, gala electrode boilers distinguished by the presence of the heating device with a simple automatic control system.



Special attention deserve the multifunction control units are designed for a specific algorithm of the electric heaters. The installation and assembly of the electrode boiler without certain knowledge would be difficult to produce with his own.

The process of installation is reduced to the installation of the boiler directly Galan, attachments, piping, wiring and electronic injection for the heating system.



Package delivery
The set of electrode boiler from the manufacturer includes:

electrode assembly capacity of 3-50 kW
power unit including circuit breaker, contactor and modular digital thermostat water
Digital thermostat for the air block "climate control».
Attachments (expansion tank and pump) in the package are not included, so their parameters are pre-calculated, and the equipment must be purchased separately.



Requirements for the heating system
To ensure the normal operation of the heating system is necessary to observe a number of requirements:

the estimated heating system must be closed two-pipe type with diaphragm expansion vessel (information on the volume of 1 / 10L)
the boiler is mounted vertically, without exceeding the level
radiators when the boiler piping is recommended that the ratio of the diameters of the boiler unit (Ø 32), the riser Ø32 (1 "/ 1/4), line (Ø 25), the conclusions on the radiator (Ø 20).



For connecting to the heating system recommended by the cast iron, aluminum and bimetal types of radiators, as well as registers of the system in compliance with the standard coolant and engine capacity.

Tying electrode boiler
Tying electrode boiler subject to the following components of the heating system:


expansion tank
circulation pump
security group the return valves and strainer

Bay coolant valve Crane emptying the system
tap.



Prior to installation and the installation of the electrode boiler Galan is necessary to make calculations of components of the heating system. The boiler output is calculated according to floor space and ceiling height, as well as the material walls of the house or apartment. Then determine the place of the future installation of the boiler and develop the scheme and isolated roads, type of radiators.

If you plan to install the boiler to an existing heating system (in most cases), the calculation may be limited to the correct strapping and connecting the power unit and thermostat.

We make installation of the boiler Galan
For the installation of the boiler Galan use plastic pipes. In the horizontal wiring necessary to create a slope of 3 degrees. The height of the placement of the vertical riser should be at least 2 m above the boiler. Electrode boiler requires grounding to the grounding impedance of 4 ohms.



After the installation of the boiler make placement of the expansion vessel and circulation pump. The shut-off valves in the pipe line is set after the return and the expansion tank. Gates set before and after the radiator group.

How to make the installation of the boiler and attached standard equipment shown here.



Schemes boiler connection
There are several circuits connecting the boiler: a basic standard, parallel connection and connection to the system of floor heating for a rated voltage of 220 and 380, and many other equally interesting schemes

.

The simplest connection diagrams are considered single-phase or three-phase electrode boiler electrode boiler with control electronics, circulating pump and filter. But no matter what scheme you have chosen not to implement in life, you must provide the installation ground.



For example, the electrode boiler Galan center 3 with the nominal value of the power consumption of 3 kW, according to the basic wiring diagram, it is necessary voltage with a frequency of 50 Hz and a maximum current per phase of the boiler 13, 7 A and starting current of 5 A.



This connection is performed using conductive copper core wire 4 mm2 and to the heating system via the clutch control 32 mm.



However, the electrode boiler was ordinary boiler if the heating system is not present controls with measuring unit and adjusting operating parameters of CROS.

Electronic boiler control
The electronic control unit is equipped with a sensor unit, an interface cable and plug for connection to the RS232 standard interface. Schematically, the electronic boiler control (CROS) consists of a controller, power control of the boiler, electronic circulation pump control switch.



There are current controller and coolant conductivity. Current controller limits the current at the working level, given when the system starts.



conductivity controller performs the functions of determining the state of the coolant: off the boiler when the carrier of the critical heat conductivity level or continues. Sensors of conductivity and temperature of the medium outrigger.

To install the control unit cable using a wire core section 0, 12-2, 5 mm2. The ends of the cable to the control circuits cleaned by 7-10 mm. Screw terminals loosen and install wire. Tighten the terminals must be a force not exceeding 2 Nm.

Make the connection of the control unit will help video.



After installation and connection to the heating system is pumped into the electrolyte and generate heat adjustment parameters. To control the current in the system using hinged clamp.
