Zilant system of balanced ventilation with heat recovery (SBVHR)

Zilant decentralized controllable system of balanced ventilation with heat recovery (SBVHR) is a simple and effective solution that provides the energy-saving ventilation of apartments, separate houses, social and commercial institutions.

Trade House-Zilant LLC produces and offers two modifications of the innovative compact and decentralized system of energy-saving balanced ventilation with heat recovery (SBVHR) under “Zilant” trade mark (SBVHR 200 and SBVHR 125), which are designed for the procurement of permanent and capital repair facilities at special minimal prices.

Advantages of Zilant SBVHR:

Zilant SBVHR solves the following problems:

Too stuffy in the room

Если в помещении душно

Stagnant air cumulates the carbon dioxide, which gives you a feeling of stuffiness and lack of fresh air. The increase of carbon dioxide level negatively affects the human health (headache, fatigue etc.).

Street noise

Уличный шум

If the windows are opened you will be affected by street noise or too cold air (in winter).



There is some weakness, fatigue, drowsiness because of the lack of oxygen. Due to the standards, the normal oxygen content is to be for about 21%. However, the present-day tight windows and doors block the natural air intake.



Dust-loaded air comes into the room through opened windows.

Mouldy smell

Затхлый запах

It is caused by the lack of ventilation. The latter results in the high humidity.



Opened windows cause the drafts and intake of cold air in winter. This may lead to getting cold.

Steamy windows

Запотевание окон

Insufficient ventilation of the room is possible to lead to the high humidity, which is then condensed on the cold window surface.



Wind-borne insects, fluff and fine debris come into the room through opened window.

Fungi on walls

Грибок на стенах

High humidity leads to the wet condensation not only on windows, but also on wall papers, which later become a great medium for mold fungi growth.

Need to switch off the conditioner

Необходимость отключать кондиционер

Windows are not to be opened during conditioner operation. Opening the window, we disrupt the heat insulation of the room against the street.

SBVHR elements

Ventilating grills

The modern design of SBVHR inner grill harmoniously fits the interior of any room. The external grating is equipped with the rust-resistant canopy, which ensures the proper operation of system in case of front wind peculiar for the high-rise buildings.

Air filtration

The cleaning of incoming and extract air is carried out by two inbuilt filters of G3/G4 or F5 classes. Filters ensure the supply of fresh air, cleaned from dust, insects, pollen and microorganisms, as well as protect the elements of system from choking.


SBVHRs are equipped with five-speed axial-flow ventilators, which have the low energy consumption (from 15 to 30W). Ventilators are connected to the main with voltage of 220V. Ventilators motors have the integrated overtemperature control and ball bearings, which extend the operation time.

Extension-type air duct

Extension-type air duct of round or rectangular cross-section is made up of zinc-plated steel. Its length varies from 400 to 750mm. The external surface of air duct has the layer of pressure-sensitive foiled and foamed polyethylene that ensures the heat and sound insulation.

System operation

In order to switch on the System, it is required to:

1. Apply the voltage on the switch-board.
2. Press the “MODE” button. Thereafter, the adjustable ventilating grill with electric actuator will be opened and extraction ventilator will be switched on.

There are 4 System operation modes:
1. Air intake mode. System only intakes the air.
2. Air extract mode. System only extracts the air.
3. Energy saving mode. Main operation mode. If switching on the System, it starts operating in this mode.
4. Ventilation mode.

Switching between modes is performed by pressing the “MODE” button on the control unit or remote control.

System performance (ventilator spin speed) is adjusted by pressing the “SPEED” button on the control unit or remote control.

Energy saving mode is a main operation mode, when the System alternatively works in air extract and intake modes.

Running time of System in the energy saving mode (whether it is air extract or intake) may be one of the following: 20 sec., 30 sec.; 35 sec.; 40 sec.; 50 sec., 60 sec., 70 sec., 80 sec., 90 sec.

Approximate correspondence between the outdoor temperature and running time of System, which operates in the energy saving mode (whether it is air extract or intake), is the following:

from +35° С to +40°С : 20 sec.

System management

Control unit coordinates the work of electrical screen with reversible motor, ventilator with reversible motor and ventilators.

There are the following buttons on the control unit:
1) «OFF»
2) «TIME»
3) «SPEED»
4) «MODE»
Moreover, there are 9 indicator lamps on the control unit.

«SPEED» has 5 indicator lamps (I, II, III, IV, V), which correspond to the ventilator spin speeds of 40%, 50%, 60%, 100% of the maximum spin speed.
«MODE» has 4 indicator lamps (М1, М2, М3, М4), which correspond to 3 System operation modes and supercooling protection function.
«TIME» has 9 modes: 20, 30, 35, 40, 50, 60, 70, 80, 90 seconds. If pressing the “TIME” button, we will get the following correspondence between the indicator lamps and defined time intervals: I–20sec, M1–30 sec, II–35 sec, M2– 40 sec, III–50 sec, M3–60 sec, IV–70 sec, M4–80 sec, V–90 sec.

SBVHR operation principle


I CYCLE. The extracted warm air is removed from the room and, moving through the ceramic energy recuperator, gradually warms and humidifies it, giving up to 97% of its heat. After a while, when the ceramic recuperator is heated, the system is automatically switched to air intake mode.

II CYCLE. Fresh outdoor air, moving through the ceramic energy recuperator, is humidified and heated to the room temperature by means of heat accumulated in the recuperator. When the recuperator becomes cold, the ventilator is switched to the air extract mode again. The cycle is repeated.

spvvr_4Main indoor heat losses:
Windows, doors – up to 17%
Ventilation system – above 60%
Outer walls, roofing – up to 20%

The criterion of indoor air quality is a continual flow of clean fresh air with the adequate moisture, as well as the simultaneous removing of used air masses, which guarantees the comfort microclimate. The volume of removed air is to be the same as incoming one. To do this, the operation of intake (responsible for air intake) and extract ventilation (air masses removing) is to be coordinated by the inboard automatic equipment of ventilation system.

Balanced ventilation of rooms will refresh the air at a short period of time, creating and keeping the ideal microclimate. This means that the best ventilation is balanced one.

Savings calculation

Calculation of savings for multifamily residential building

For example, the total building area – 9000 sq.m.
Average heat energy consumed by the building during heating season – 2000Gcal
Apartment area of 100sq.m. uses – 2000*100/9000=22,2Gcal
Heat energy price – 1300RUB/Gcal*22,2=28860RUB
Thus, the savings – 28860  50% = 14430RUB/1 heating season

Calculation of savings for private house

For example, private house area – 80m2
Heating expenses – 30000RUB per season
Thus, the savings – 15000RUB per season
