It is recommended to use the following types of liquids as heat-transfer agents for all of the “Ochag”, ”Geyser”,
“Vulkan” electrode boilers of the “Firma “Galan” Joint-Stock Company which are listed in this table:
•
“Galan-Potok” low-freezing liquid with special rust prevention components and additives against formation of
scale and scum (freezing temperature: -40
º
C, life expectancy: no less than 5 years, warranty period: 1 year)
(hereinafter referred to as “low-freezing liquid”);
•
Potable water (defined by the Sanitary Regulations and Rules No. 2.1.4.559-96), distilled water, snow melt
water, rain water (filtered water) the specific electric resistance (hereinafter referred to as “resistance”) of
which is no less than 1300 Ohm/cm at a temperature of +15
º
C.
ATTENTION!
It is strictly forbidden to use low-freezing liquids (antifreezes) such as “TOSOL”, “Arktika”, “Tvoy Dom”, etc. as heat-
transfer agents since they are not intended for a use by the electrode boilers.
The “Firma “Galan” Joint-Stock Company regularly performs technological
improvements of electric boilers, therefore their technical characteristics can slightly differ
from characteristics resulted in the table above.
Boilers construction
Depending on the boiler power the electrode boilers produced by the “Firma “Galan”
Joint-Stock Company fall into the following categories:
•
Single-phase electrode boilers (“Ochag-2”, “Ochag-3”, “Ochag-5”, and
“Ochag-6” electrode boilers);
•
Three-phase electrode boilers (“Geyser-9”, “Geyser-15”, and “Vulkan-25”
electrode boilers).
Single-phase electrode boilers consist of the following components:
•
Metal case with inlet and outlet connections (a case functions as the second
electrode and ionization chamber);
•
Rod electrode with current lead and hermetic electric bushing insulator;
•
Two terminal groups with protective housings (phase terminal is located at the
bottom of the single-phase electrode boiler; neutral wire terminal and ground
wire terminal are on the side of the single-phase electrode boiler).
Three-phase electrode boilers consist of the following components:
•
Metal case with inlet and outlet connections (a case functions as ionization
chamber);
•
Base on which three electrodes with current leads and hermetic electric bushing
insulators are installed;
•
Terminal group with protective housing.
The operating principle is the same for all electrode boilers. It is discussed below.
Advantages of the electrode boilers
The electrode boilers of the “Firma “Galan” Joint-Stock Company are 2-3 times
cheaper than the boilers of the same power produced by other manufacturers and have the
following significant advantages:
•
Significant energy conservation is achieved by high electrode boilers efficiency
which reaches 98%. By this indicator electrode boilers surpass the existing
