Heat and energy recovery ventilators HRU-ERGO

Photo of product family: Heat and energy recovery ventilators HRU-ERGO


Heat and energy recovery ventilators supply fresh air heated by the outgoing air to the facilities.Heat and energy recovery ventilator has high efficient counter flow heat
exchanger.

The clearance between the fibers is very small, so only the moisture molecules of small
diameter can go through, the odor molecules of larger diameter are unable to pass through it.

By this means, the temperature and humidity can be recovered smoothly, and prevent
the pollutants infiltrating to the fresh air.

Heat and energy recovery ventilators with enthalpy


The HRU-ERGO heat recovery ventilator is a suspended unit
with an extremely efficient counter-flow heat exchanger.
The heat exchanger is made from plastic and processed
cellulose which has a high water vapour permeability ratio,
good air tightness, and good resistance to ageing.
The spacing between the cellulose fibres allows free passage
of water vapour molecules. Larger molecules, like those of
odours, cannot pass through the heat exchanger.

This prevents the contamination of the fresh air supplied indoors.
The heat recovery ventilators are available in an output range
from 250 m3/h to 1000 m3/h.

A standard HRU-ERGO heat recovery ventilator features
10-speed energy-efficient fans, automatic air bypass,
defrosting mode (based on a fan speed control algorithm),
2 air filters, and steel duct connections.
Optional accessories include the HDE-CO electric heater and
the HDW water heater, the HRU-CONTR-TPAD touch-screen
controller, as well as CO2 and air humidity sensors.

The HRU-CONTR-TPAD touch-screen controller is designed
for operation of heat recovery ventilators. The intuitive
software interface and extensive functionalities enable easy
management of HRU-ERGO heat recovery ventilators.

Its modern design will seamlessly match every energy-efficient
home interior of today.

Counter-flow heat exchanger for heat recovery ventilators


The HRE-ERGO counter-flow heat exchanger is intended for
the HRU-ERGO heat recovery ventilators. The heat exchanger
is made with a paper material which features a high water
vapour permeability, good air tightness, and good resistance
to ageing.

The spacing between the cellulose fibres in the material allows
free passage of water vapour molecules. Larger molecules, like
those of odours, cannot pass through the heat exchanger. This
prevents the contamination of the fresh air supplied indoors.

Electric duct heater


HDE-CO electric duct heaters can be used as optional heaters for the HRU-ERGO energy recovery unit.
Depending on the functions of heaters in ventilation system, duct heaters can be divided into:
- preliminary
- secondary
A preliminary heater is installed on the exhaust duct of HRU (fresh air from outside) and it is used
to preheat the air supplied to the heat recovery unit.

The preliminary heater is fitted to prevent freezing of the heat exchanger at extremely low outside
temperatures and it does not affect the temperature in the room. The standard HRU-ERGO unit has an
automatic frost protection function, which protects from freezing by periodic altering of fans’ speed.

It is recommended to use a heater with one contactor type HDE-CO1 or with two contactors type HDE-C02.
A secondary heater is installed on the supply air duct (fresh supply air to the room) and it is used for
additional heating of the supply air temperature. After connecting the heater to the HRU-ERGO unit we are
able to task the temperature in the room when we feel that thermal recovery alone is not enough for our
comfort. We recommend a duct heater HDE-CO2 with two contactors.
