Decentralized heat recovery ventilator TwinFresh Easy RL7-50-17

What is VENTS TwinFresh Easy RL7-50-17?

VENTS TwinFresh Easy RL7-50-17 is a local single-room recuperator designed to ventilate through one wall opening with a diameter of 160 mm. It is a decentralized unit with a regenerative ceramic heat exchanger that alternately supplies and extracts air in 70-second cycles during heat recovery mode. This design is very practical for renovations and in places where a central duct system is not feasible.

Main advantages

• Ceramic heat accumulator
  The regenerative ceramic exchanger stores heat and then returns it back to the room, helping to provide more balanced ventilation.
• Antibacterial treatment
  The exchanger is antibacterially treated, and the treatment effect is designed for long-term reliability of up to 10 years.
• Simple standalone operation
  The device works as a straightforward local solution for one room, without the need for a central ventilation system.
• Control via panel or remote
  The unit can be controlled using the wired wall panel KV1 TwinFresh Easy or the hand-held remote control RK TwinFresh Easy RL-50.
• Convenient maintenance
  The built-in filter maintenance indicator makes timely cleaning or filter replacement easier, and the optional F8 filter provides better protection against particles and allergens.

Operation and control

In heat recovery mode, the fan automatically switches between air supply and air extraction at 70-second intervals. The ceramic core is first heated and then releases the heat to the fresh air entering the room. In addition, there is also a ventilation mode, where the unit operates as either continuous supply or continuous extraction at the selected speed.

Control is via the wired wall panel KV1 TwinFresh Easy or the hand-held remote control RK TwinFresh Easy RL-50. The internal grilles have manual dampers, so you can additionally adjust the airflow mechanically. Filter maintenance is made easier by the filter indicator, and a standard G3 filter is included as standard. If needed, it can be upgraded with an additional F8 filter, taking into account that the maximum air flow is reduced to approximately 40 m3/h.

Technical specifications

Energy efficiency

For this model, it is important to distinguish between two values. The ceramic material of the exchanger has a theoretical regeneration capability of up to 97%, while the certified efficiency of the entire unit is 92%. For the user, this means the unit efficiently recovers heat during ventilation and helps reduce heat losses in the room.

Frequently asked questions

Does the unit operate independently through one wall?
Yes. It is a decentralized local recuperator that is installed in one wall opening with a diameter of 160 mm and does not require a central duct system.

How does heat recovery work?
In heat recovery mode, the unit automatically alternates between supply and extraction air in 70-second cycles, with the ceramic accumulator first storing the heat and then releasing it.

How do I control the unit?
Control is possible via the wired wall panel KV1 TwinFresh Easy or via the hand-held remote control RK TwinFresh Easy RL-50.

Can the filter be upgraded?
Yes. The standard G3 filter can be replaced with the optional F8 filter, whereby the maximum air flow is reduced to approximately 40 m3/h.

Conclusion

VENTS TwinFresh Easy RL7-50-17 is a reliable local solution for ventilation and heat recovery in one room. With its ceramic accumulator, simple control, and the option of continuous 24/7 operation, it is an excellent choice for more comfortable and more controlled air.
