Decentralized recuperator TwinFresh Atmo Wi-Fi

Compact local single-room recuperator

VENTS TwinFresh Atmo Wi-Fi is a decentralized single-room ventilation unit with heat recovery, designed to supply fresh air through one wall opening. Since it operates in a reversible, bidirectional mode with a regenerative ceramic exchanger, it helps maintain a pleasant indoor climate without unnecessary heat loss and without complex ducting throughout the house. Control is simple: via the built-in panel, remote control, or smartphone over Wi‑Fi, and connection with Google Home or Google Assistant is also available.

Main advantages

• Up to 95% heat recovery
  The ceramic regenerative exchanger helps utilize the heat from extracted air, so ventilation causes less heating loss and can help reduce room ventilation costs.
• Wi‑Fi control and voice control
  Settings, speeds, and operating modes can be changed remotely in the app, and the unit can also be integrated into voice control via Google Home.
• Automatic operation based on room conditions
  The built-in humidity sensor activates automatic mode when humidity rises, for example after showering, and the light sensor supports night mode and operation adjustment in the dark.
• The right speed for every moment
  Three speeds, recuperation mode, supply, exhaust, party/boost, night mode, and a weekly schedule allow the unit to operate according to the actual needs of the room.
• Automatic anti-draft shutoff dampers
  When the unit is switched off, the dampers close automatically and help prevent cold air infiltration and unpleasant drafts through the wall opening.

How it works

The unit alternately extracts stale air from the room and supplies fresh air, while the ceramic heat exchanger accumulates energy from the extracted stream and transfers it to the supply stream. This makes ventilation much more pleasant than simply opening a window, since heat is not lost to the same extent. In recuperation mode, the airflow is lower than in classic ventilation mode, which is a normal part of the regenerative cycle and enables more efficient heat recovery.

In practice, this means less manual control and more comfort. If humidity rises quickly after bathing in the bathroom, the unit can automatically switch to the appropriate mode. In the evening, you can set it to night mode so it runs more quietly, or use your phone and a voice command to quickly switch to a stronger boost mode when you temporarily need more intensive ventilation in the room.

Installation

VENTS TwinFresh Atmo Wi-Fi is a local single-room ventilator, so it is installed through one wall opening with a 160 mm connection and does not require ducting throughout the building. It is suitable for installation in walls up to 500 mm thick. The unit has protection IP24, and operates with supply air in the range from -20 to +40 °C and with ambient air from +1 to +40 °C and a maximum relative humidity of 65%.

Technical specifications

Frequently asked questions

How much heat does the unit actually save?
The model achieves up to 95% heat efficiency, so during ventilation it loses significantly less heat than when opening a window. In practice, this means better heat retention in the room and less need for additional heating.

What does energy class A+ mean?
A+ means the unit is designed for very economical operation. For this model, this is also confirmed by the low average annual electricity consumption of 37 kWh/a and the positive annual heat savings of 45 kWh/a.

Does the phone need to be nearby all the time for the unit to work?
No. The unit can operate completely independently with the built-in panel, remote control, and automatic sensors. The app via Wi‑Fi is an additional advantage for more convenient remote control.

Does this replace a central ventilation system?
No, this is a local recuperator for one room. It is intended for ventilation and heat recovery through one wall opening, not for ducting air throughout the entire building.

How quiet is it at individual speeds?
At 3 m, the sound pressure is 11 / 21 / 27 dB(A) for 1st, 2nd, and 3rd speed, and at 1 m it is 20 / 30 / 36 dB(A). This allows very quiet operation at lower speeds and higher performance when needed.

Conclusion

VENTS TwinFresh Atmo Wi-Fi is a thoughtful solution for fresh air in one room, where you want to combine heat recovery, quiet operation, and modern app-based control. If you are looking for a local recuperator that automatically responds to humidity, is easy to install through one wall, and maintains comfort without unnecessary heat loss, this is a very convincing choice.
