Convenient and flexible: profi-air 250 flex

Easy to operate and particularly flexible: The new FRÄNKISCHE profi-air 250 flex ventilation unit can be easily put into operation via software, and controlled via an app. By means of optionally available components, the users can customise their individual device for heat recovery ventilation.

profi-air is a complete system for heat recovery ventilation. A combination of tried-and-tested classic and tunnel pipe systems, ventilation grills from the starline collection and various ventilation units allow FRÄNKISCHE to offer all components for future-proof ventilation systems from one source. A new addition to the range of products is the profi-air 250 flex ventilation unit with air volumes of up to 250 m3/h, specifically designed for single-family homes.

profi-air 250 flex with switchable air connection

The new ventilation unit provides everything that its name implies – namely the highest degree of flexibility in installation and handling. profi-air 250 flex can be either attached to the wall or installed on the floor. A supply air connection at the bottom of the device is available as an option.

Additionally, the easySWITCH function offers a decisive advantage: With the standard, switchable air connection, the ventilation unit can be easily set to right or left operation directly on site – the HVAC technicians thus remain flexible and have a suitable solution for each installation situation.

Wholesalers and installers can always use the same unit with profi-air 250 flex, and quickly react to the respective circumstances. The end customers are at an advantage, too: They can still decide on the final location of their ventilation units during the actual installation.

Optional accessories for profi-air 250 flex

Thanks to a comprehensive range of optionally available accessories, each user can configure their customised profi-air 250 flex ventilation unit. A defroster heater that is now installed directly in the unit saves space in the installation room and offers efficient frost protection. An enthalpy heat exchanger, which also recovers humidity along with heat, is also part of the profi-air 250 flex range of accessories. This prevents the rooms from drying out even in winter, which significantly increases the comfort of living.

 

Humidity and VOC (Volatile Organic Compounds) sensors can be integrated into the ventilation unit as well. The VOC sensor measures the air quality, and automatically adjusts the air volumes. Room humidistats are also optionally available for the ventilation unit. If the profi-air 250 flex is connected with two room humidistats, it bears the energy label A+. Without humidistats, it corresponds to the energy efficiency grade A, which is the case for all FRÄNKISCHE ventilation units.

Ventilation control via profi-air cockpit app

The new ventilation unit by FRÄNKISCHE is easy to handle and can be controlled in different ways: Either via an integrated, user-friendly control unit, an additional wireless remote control, or by means of the new profi-air cockpit app. The end customer uses the app to switch the ventilation modes, change the weekly programme or enable the sensors. The new application helps the residents to keep in mind the interval of filter replacement, as well as to switch on night setback or holiday mode if required. The digital operation aid is available for free download for iOS and Android gadgets in the respective stores.

Software for specialists for step-by-step commissioning assistance

While the profi-air cockpit app is a practical aid for the end customer, the new profi-air cockpit pro software is intended for HVAC specialists. The computer programme makes it easier for the installers to put the ventilation units into operation, and guides them through all adjustment steps: They can, for instance, enable the defroster heater and create a weekly programme. profi-air cockpit pro has been designed for computers featuring Windows operating systems and is available for free download at www.fraenkische.com. A commercially available USB cable connects the commissioning laptop with the ventilation unit.

profi-air 250 flex is equipped with G4 coarse filters for extract and supply air; an F7 fine filter is also available for supply air as an option. The base of the new ventilation unit is under 0.3 m2 and thus particularly small for its performance class, so it requires virtually no space in the technician room. The device with changeable air connections fits into standard cabinets with the dimensions of 60 x 60 cm. So the new product by FRÄNKISCHE, which will be commercially available as of May 2019, discreetly fits into any surroundings.
