INTENDED USE
PRINCIPLE OF WORK
The basis of the technical solution for recuperation ventilation is the countercurrent, with a
continuous thermal cycle, a copper heat exchanger, which makes it possible to form two
different-directed airflows in the volume of one cylinder (Fig. 1).
Warm exhaust air that is removed from the room, passing through a copper heat exchanger
transmits its warmth to the counter stream of fresh air from the outside.
The system allows recover heat, which contributes to increasing the overall recuperation
rate and allows maintain the optimum humidity mode in the room. Taking into account that
air streams are separated and regulated at levels “inflow” – “exhaust”», there is no mixing of
different-directional air flows.
High velocity of the flow with sufficient heat transfer efficiency ensures removal of up to
90% moisture in a dispersed state, preventing its condensation and freezing of the heat
exchanger at low ambient temperatures.
DESCRIPTION OF THE DEVICE
Ventilation units “PRANA-150”, “PRANA-200C”, “PRANA-200G” are intended for creation and
maintenance of healthy microclimate in premises.
These systems are recommended for use in residential and public facilities (apartments,
houses, office premises, educational establishments, kindergartens, etc.).
PRANA-150 and PRANA-200G belong to the category of innovative and reliable ducts
aimed at creating and maintaining a healthy microclimate in premises of various functional
purposes.
High energy efficiency and significant air exchange capabilities make it possible to apply
these ventilation units for organizing domestic ventilation.
Technologically, the system is a monoblock with high-efficiency counter-current copper
recuperator ready to use in accordance with the design and assembly tasks and conditions.

ADDITIONAL FUNCTIONS
“Mini heating up” function
For additional comfort in equipping residential premises with ventilation units PRANA of
residential-and-public and semi-industrial series, the function of air “Mini heating up” is
provided for. It can be switched on by pressing the “Mini heating up” button on the remote
control or in a mobile application (see the remote control manual included in the list of
standard equipment).
After having activated the function of “Mini heating up”, the temperature of the infl ow air
increases by 3-5 ºC.
When the motors are switched off and the cover of the recuperator is open, this function
additionally plays the role of an air heat curtain.
WARNING! DO NOT SWITCH ON “Mini heating up” , if the outside air temperature is +20 ºС
and above!
Function “Winter Mode”
Function “Winter Mode” is intended to prevent the icing of condensate drainage during the
cold season or to freeze it if icing has occurred.
WARNING! To avoid icing and to ensure the system operates correctly at the minus
temperature from the outside - the use of the Winter Mode is mandatory.
TECHNICAL DATA
Power supply: AC: 230 ± 10% V. Class of insulation: II. Degree of protection: IP 24.
Control: remote control, mobile application.
The body of the system is thermally insulated. Double protection against frontal blasting.
The function of “heating with minimally-raised temperature” and “freezing”.
The established service life of the system: 10 years. The warranty period: 2 years.
The use of the system is designed for long-term operation at air temperature in the range
from -30 ºС to +50 ºС.

In mode «AUTO» after engine shutdown, «Winter mode» will work for 30 minutes to prevent
icing in the system, which may result in reduced effi ciency or condensate drainage
complications.
Preheating element (additional option)
Recuperators that will be used in rooms with excessive humidity in the cold climate are
recommended to be equipped with an additional heating element.
Passive mode
The operating mode of the ventilation system with the open lid of the recuperator and
switched off motors. It lies in the movement of uncontrolled airfl ows through the recuperator
due to the difference in pressure and temperature inside and outside the premises. It is
allowed to use, when the difference between outside and inside temperatures is no more
than 5 o C.
Defrosting
WARNING! In the cold season, the imper operation of the recuperator is likely to freeze it!
When freezing, it is necessary to activate function «mini-heating up» with engine switched
off for at least 60 minutes, and let it unfreeze, then turn on the recuperator to the required
mode.

Bidirectional ventilation unit with heat recovery “PRANA” is a monoblock ready for use in
accordance with design and assembly tasks and conditions.
The system is mounted in a hole of the appriate diameter in the upper part of the wall
adjoining the outside, at a distance of no less than 100-150 mm from the ceiling or walls. The
through hole should be a slope of 3-5 degrees towards the outside. The operating module of
the ventilation unit is mounted in the hole using a seal (Fig. 4).
The length of the working module should correspond to the thickness of the wall in which
the installation will be carried out. In order to ensure the normal operation of the system, it
is necessary that its body facing the the outside extends beyond the wall by 1-2 cm to the
beginning of the air intake (Fig. 4).
