High efficiency heat recovery unit > 80% (EN308). The range includes 6 sizes for air flow rates from 100 to 3.500 m³/h. Each FREETIME-S model comes with its own regulation as standard.
The FREETIME-S Premium is a self-regulating unit either equipped with a water heating coil or with an electric heating coil for temperatures down to -10°C and an extensive regulating module.
The unit is always provided for an indoor installation, with top connections.

Safety switch
Differential pressure switch on inlet filter F7
Differential pressure switch on each fan
Modbus or Bacnet possible as standard
Fan
Fan with free-running wheel
Direct drive DC motor with high efficiency electronic modulation (EC), thermal protection and integrated speed control
The EC technology guarantees a limited energy consumption by controlling and checking the operating point (regulation between 10 and 100%)
Low noise level for better acoustic comfort
Exchanger
Rotary heat exchanger (sorption wheel) in aluminum with high efficiency and variable speed (EUROVENT approved)
Efficiency > 80% (EN308)
Filter
The filters are mounted directly in front of the components for optimal protection
The filters are mounted on slides with lip sealilng for efficient airtightness
The basic configuration of the FREETIME-S is equipped with an F7 filter- ISO 16890 ePM1 - 55% (supply) and an M5 filter- ISO ePM1 50% (extraction)
F7 high-efficiency filter: 10x larger filter surface than a gravimetric filter and 2.5x longer life
Additional fresh air filter available as an option
A double filtration can be provided on the fresh air. However, the pressure drop (see spare filters) must also be taken into account in the technical selection of your device!
Versions
