Local heat recovery ventilator TwinFresh Style

What is VENTS TwinFresh Style?

VENTS TwinFresh Style is a decentralized bidirectional local heat-recovery ventilator designed for ventilating a single room without a central duct system. It is installed in a single wall opening, making it very suitable for renovations, retrofits, and spaces where classic heat recovery ventilation is difficult to implement. The unit uses a regenerative ceramic heat exchanger and operates at 3 speeds, so the airflow can be adjusted to the actual needs of the room.

Main advantages

• Heat recovery up to 90%
  With the regenerative heat exchanger, part of the heat from the extract air is returned to the fresh air, helping reduce heat losses during ventilation.
• Standalone installation in one opening
  No central duct system is needed for operation; the unit is installed directly in the outer wall through a 160 mm duct.
• Humidity-based automation
  The built-in relative humidity sensor helps the unit adjust operation in automatic mode according to the actual needs of the room.
• Closable anti-draft shutter
  When the fan is switched off, the air shutter closes automatically and reduces unwanted infiltration of cold air.
• Flexible control and filtration upgrade
  A control panel on the unit, the included remote control, weekly schedule, night and party modes, and the option to connect multiple units in a local network are available. The standard G3 filter can be upgraded with the G4 or F7 accessory.

Operation and control

TwinFresh Style offers automatic operation, heat-recovery ventilation, ventilation only, and extract only modes. In practice, this means you can use the unit for everyday air exchange, for faster removal of moisture or odors, and for energy-efficient ventilation with heat recovery. Operation is simple: a built-in control panel and the included remote control are available, so the basic functions are always within reach. Additional functions such as a weekly schedule, night mode, party mode, and filter maintenance indication contribute to more worry-free use. A special feature of the system is the option to locally connect multiple units, which is useful in spaces that require coordinated ventilation.

Technical specifications

To adapt to wall thickness, duct length extensions of 350, 500 or 700 mm are available.

Energy efficiency

The main advantage of this local heat-recovery ventilator is the transfer of heat from the extract air to the supply air. When ventilating with cold outdoor air, the unit helps retain part of the heat in the room, making ventilation more comfortable and less wasteful. This is especially useful in spaces where you want fresh air without major heat losses.

Frequently asked questions

Do I need a central ventilation system?
No. TwinFresh Style operates independently through a single wall opening, so it is suitable even where a central system is not feasible.

How loud is the unit at the lowest speed?
At speed I, the sound pressure at 3 m is only 1 dB(A), and at 1 m it is 10 dB(A), so operation at the lowest setting is very discreet.

Can I connect multiple units together?
Yes, the units can be locally connected and their operation coordinated, which is convenient for multiple adjacent rooms.

Can the filter be upgraded?
Yes. The standard G3 filter can be replaced with the G4 or F7 accessory, where F7 improves filtration but reduces the maximum airflow to approximately 40 m3/h.

Conclusion

VENTS TwinFresh Style is a practical solution for anyone who wants efficient ventilation of a single room with heat recovery, without a complicated duct system. It offers automatic operation, simple control, and the possibility of customization with additional filters and duct extensions, so it adapts well to different residential conditions.
