Retrofit old buildings with the AlphaFreshbox 60 individual room ventilation system

The AlphaFreshbox 60 is a single room ventilation system for optimum decentralised ventilation of separate rooms in flats, houses, social and commercial buildings. An air duct network is not required. The ideal solution for simple and efficient ventilation for retrofitting in old Buildings.

The combined operation of the AlphaFreshbox 60 with heat recovery and an air conditioner is not only the most effective way to create a comfortable climate in the room, but also a considerable cost saving, as the heat exchanger stores the heat in winter and the coolness in summer.

The housing is made of polymer-coated metal and decorated with high-gloss stainless steel. The modern design blends the ventilation unit perfectly into any room design. The removable front cover makes it easy to change filters and clean the ventilation System.

Ventilation is radon protection

If the radon activity concentration in cellars and living rooms is low, the BMU recommends regular mechanical cross-ventilation (window ventilation) of the rooms. Radon-contaminated air is quickly transported outdoors in this way.

If radon levels are elevated, manual ventilation can no longer sufficiently reduce the radon concentration. Here it makes sense to find a technical solution. Automated ventilation ensures that there is a sufficiently high air exchange and thus the radon concentration can be permanently lowered. Since radon usually enters the building via the basement rooms and spreads to the higher floors via stairwells, cables and pipe connections, reducing the radon concentration in the basement helps to significantly reduce the total radon load in the Building.

Function and operating modes

Cold outside air flows through the filter and heat exchanger and is led into the room by the supply air axial fan. Warm extract air is extracted from the room via the filter and heat exchanger and is led outdoors via the extract air axial fan. The heat transfer process takes place in a heat exchanger, in which thermal energy from the extract air is transferred to the fresh supply air. This reduces heat loss and minimises heating costs in the cold season. The supply and extract air streams are separated from each other so that odours and bacteria from the extract air stream cannot be transferred to the supply air stream.

Both supply and extract air streams are cleaned by two built-in air filters of filter class G4. The filters remove dust and insects from the supply air and prevent contamination of the ventilation system. In this way, you maintain a healthy indoor climate. Replacement filters for both supply and extract air are available as accessories.

The system must be equipped with a sensor speed switch.

The control enables ventilation in three operating modes:

1. Minimum air delivery rate 30 m³/h and noise level 22 dB(A)
2. Medium air flow rate 45 m³/h and noise level 25 dB(A)
3. Maximum air flow rate 60 m³/h and noise level 29 dB(A)
