VENTO V50-1 / V50-1 S / V50-1 Pro / V50-1 S Pro
DESIGN AND OPERATING LOGIC
The unit consists of a telescopic duct with adjustable length, a ventilation
unit and an outer ventilation hood.
The telescopic air duct includes a filter and a ceramic heat accumulator
(regenerator) inside. The square heat-insulated metal air duct has an
adjustable length.
•
- 250 up to 470 mm for the models VENTO V50-1;
•
- 120 up to 430 mm for the models VENTO V50-1 S.
The unit is equipped with a high-tech ceramic energy regenerator with
heat recovery efficiency up to 88%. Due to its cellular structure the energy
regenerator has a large heat exchange surface and a high efficiency. The
energy regenerator is featured with high heat insulating and accumulating
properties. The regenerator recovers extract air heat energy for warming up
of supply air flow. A pull cord inside of the energy regenerator facilitates its
withdrawal. The energy regenerator rests on an insulating material used as
sealer as well.
Install the ventilation unit must on inner side of the wall. It is equipped
with automatic shutters that close the air duct when the unit is off. Air is
supplied and extracted with an axial reversible EC-fan with low energy
demand. The motor has overheating protection and ball bearings for longer
service life.
The built-in filter with filter class G3 are used for supply and extract air
filtration and the regenerator anti-soiling protection.
The outer hood must be installed at outside to prevent ingress of large
objects and water into the unit.
The integrated automation enables two-speed operation of the unit
(minimum or maximum speed):
ventilation mode (air supply or air extract);
reversible operation mode with heat regeneration.
The external control and power unit SEA-T12 or the control panel SEA is
used for operation mode control.
The delivery set of the units VENTO V50-1 Pro / V50-1 S Pro includes the
control and power unit SEA-T12 consisting of the control panel SEA and the
12W transformer AT-12.
The single control and power unit SEA-T12 enables connection up to 4
units and their integration into a central controlled ventilation system.
The following components are required to arrange a central controlled
ventilation system consisting of from 4 up to 12 ventilation units:
•
required number of VENTO V50-1 units (no control unit is included);
•
control panel SEA;
•
40W power transformer AT-40.

The unit has four ventilation modes:
•
1.
Ventilation mode (air supply or air extract) at first speed.
•
2.
Ventilation mode (air supply or air extract) at second speed.
•
3.
Reversible mode (regeneration) at first speed.
•
4.
Reversible mode (regeneration) at second speed.
In regeneration mode
the unit operates in 2 cycles, 70 seconds each.
Cycle I.
Warm stale air is extracted from the premise, flows through the
ceramic regenerator and transfers its heat energy. In 70 seconds the
ceramic regenerator gets warmed up and the unit is switched to the
supply mode.
Cycle II.
Clean cold intake air flows through the regenerator, absorbs
humidity and is warmed up with the accumulated heat. In 70 seconds
the ceramic regenerator is cooled down and the unit is switched to the
extract air mode. The cycle begins anew.
