Process stages and benefits

1 – Fresh air intake:

Entry point for clean air from outside.

2 - Control dampers:

Mechanical valves that regulate the volume of air entering and leaving the system.

3 – G4 pre-filtration:

Filters that trap larger dirt particles to protect the internal components.

4 - Plate heat exchanger:

Recovers thermal energy from the exhaust air to save on heating and cooling costs.

5 - Bypass damper:

Allows air to bypass the heat exchanger when the outside temperature is already ideal.

6 - Cooling coil:

A heat exchanger that lowers the air temperature in summer.

7 - Droplet eliminator:

Removes excess moisture (condensation) to prevent damage or mould in the ducts.

8 - Humidifier:

Adds steam or atomised water to maintain the right level of humidity for comfort.

9 - Heating coil:

A heat exchanger that heats the air in winter.

10 - Final filtration F7-H14:

High-efficiency filters that remove fine dust, bacteria and viruses.

11 - Supply fan / Plug fan:

The “heart” of the system, driving conditioned air through the ductwork.

12 - Motovario motor

A high-efficiency electric motor that drives the fan.

13 - TECO inverter

The electronic brain that regulates motor speed, ensuring maximum energy savings.

Fields of application
