TwinFresh Atmo decentralized heat recovery ventilator

What is VENTS TwinFresh Atmo?

VENTS TwinFresh Atmo is a decentralized local recuperator for a single room with a ceramic regenerative heat exchanger. It is intended for places where classic central heat recovery is too demanding or not feasible: in renovations, bedrooms, studies, living rooms, and other individual spaces. The unit is installed in a single wall opening with a diameter of 160 mm and operates alternately as an air supply and exhaust unit.

Main advantages

• Ceramic regenerator with heat and moisture recovery
  Helps maintain a more pleasant indoor climate, reduces the feeling of dry air, and supports protection against moisture and condensation formation.
• Automatic air shutters
  When the unit is switched off, the shutters close automatically and after about 2 minutes prevent unwanted drafts through the unit.
• Easy operation
  The built-in control panel and included IR remote control allow quick adjustment without complicated settings.
• Comfortable operating modes
  Night mode, weekly schedule, and party mode ensure the unit adapts to the rhythm of the room even without daily intervention.
• Possibility of multiple units in a network
  Multiple TwinFresh Atmo units can be linked into coordinated operation for balanced ventilation of adjacent rooms.
• Optional finer filter
  The standard filter is suitable for basic filtration, while an upgrade to a finer filter F7 is also available for more demanding spaces.

Operation and control

The unit offers four operating modes: Auto for heat recovery, ventilation only, exhaust only, and supply only. In automatic mode, operation adjusts to the built-in relative humidity sensor, helping regulate indoor conditions and reduce the risk of condensation. Control is via the built-in control panel or the included IR remote control. Also available are night mode, which runs at speed I for 8 hours, a weekly schedule, and party mode at speed III for 4 hours.

Additional clarity is provided by the filter replacement indicator and alarm indicator. The automatic shutters close on their own when the unit is switched off, making the unit suitable for everyday use in sleeping and living areas.

Technical specifications

Energy efficiency

For VENTS TwinFresh Atmo, two figures are important and should be read separately. The manufacturer states up to 95% as its highest laboratory or marketing value. The official Ecodesign heat recovery efficiency value is 84%, which is a stricter, regulated figure for practical comparison. Together, these two figures show that the unit very efficiently recovers heat from exhaust air.

Frequently asked questions

How noisy is the unit at the lowest speed?
At speed I, the sound pressure at 3 m is 11 dB(A), which is very quiet for everyday use in a bedroom or study.

Do I need a central ventilation system?
No. The unit operates independently through a single wall opening and is therefore also suitable for renovations or individual rooms.

Can I connect multiple units together?
Yes. Multiple TwinFresh Atmo units can be networked without additional wiring and synchronized via the first or main unit.

Is it possible to upgrade the filter?
Yes. In addition to the standard filter G3, an optional finer filter F7 is also available, which retains fine particles better, but reduces the maximum airflow to about 40 m³/h.

Conclusion

The VENTS TwinFresh Atmo local recuperator is a well-thought-out solution for a single room where you want fresher air, less moisture, and efficient heat recovery without extensive ductwork. With easy operation, automatic shutters, and the option to connect multiple units, it is suitable for modern renovations and comfortable everyday use.
