MyVallox 125C CFi
If your old ventilation unit is Vallox Digit SE, Vallox 130 E or Uponor Vent SE, MyVallox 125C CFi replaces your old ventilation unit without the need for any duct modifications. With minor changes of a few millimetres to the duct, the unit can also replace Mer-Air 21C. If your current ventilation unit is not listed above, check the replacement compatibility chart to find a suitable replacement model.
The different MyVallox 125 CFi models can replace dozens of old ventilation unit models, quickly and easily. The different models (A–G) differ from each other only with respect to the duct outlets. They can be installed in place of the old unit directly or with only minor changes to the ducts. This makes refurbishment easier and faster and saves costs.
MyVallox 125C CFi provides a fully automated, energy-efficient ventilation system. The indoor air stays fresh thanks to the integrated humidity and carbon dioxide sensors that boost or reduce ventilation according to the indoor air quality. MyVallox 125C CFi continuously supplies clean, filtered air at the desired temperature. Automatic, energy-efficient ventilation improves the comfort of living, promotes the residents’ health and saves money.
The ventilation unit’s heat recovery efficiency is excellent at nearly 80%. The efficiency figure indicates how effectively the unit uses the heat recovered from extract air to heat the supply air. Efficient heat recovery keeps the energy consumption of ventilation low even at a higher output, and separate preheating is no longer needed. The unit’s constant flow fans consume little energy, making it a more cost-efficient solution compared to your old ventilation unit.
The constant flow feature makes installation easier and ensures discreet ventilation in all conditions. Thanks to its constant flow fans, MyVallox 125C CFi can compensate for differences in pressure and keep the air flows in balance in windy locations and tall buildings, during HR cell defrosting, and regardless of the heat recovery bypass status. The constant flow feature also compensates for separate extractions. The new constant flow function also makes the installer’s job easier because it allows litre-based air flow adjustment directly from the controller.
