Thanks to a well-thought-out design, advanced technologies and system „MultiFlex“ provides users with maximum comfort and efficiency in everyday life. Simplicity and flexibility of assembly are key factor for users and installation companies.

Option of remote control by WIFI and connection to smart home system

The option to connect an external pre-heater and after-heater controlled directly by unit. Thanks to this solution, heaters are operating only when needed.

The unit stands out low weight and small height (only 16kg and 210mm). The option to install the unit under the ceiling or on the wall.

Product benefits

"MultiFlex" system allowing maximum flexibility of the unit

Low weight 16 kg

Small installation height 210mm

Installation under the ceiling and vertically on the wall

Basic description

Central unit Xflat200 with heat and humidity recovery. This is very suitable device for the ventilation of apartments and family houses, with its air output of 200 m3/h (alternatively 150 m3/h). The unit can be installed both ways - under the ceiling or vertically on the wall, due to its smart design. Xflat200 can be mounted on ceilings of normal height without getting in the way, thanks to its minimum height. The biggest advantage is the universality and flexibility of the connection.

 

The Xflat200 recuperation unit provides maximum versatility both in selection and even during installation, when changes are often already difficult. Thanks to the MULTIFLEX system, you can choose correct air output of 150 or 200 m3/h directly on the unit. The unit can also be switched between the left and right version, which practically means that its behavior is electronically adapting the direction of the flow of outdoor and indoor air. Turning the throats 90° is another and indisputable advantage during final assembly.

 

COMFORT+ and COMFORT regulation allows complete setting of the recuperation unit. The controller connects to the unit using a cable with RJ45 connectors (10 m in the package) - this guarantees a simple and secure connection. The control can be extended with a WIFI module and everything can be controlled conveniently using the web application. You can also connect the unit to a BMS.

 

The ESSENTIAL regulation is a simplified version control of the recovery unit. Still, it provides the basic and fully sufficient functions. Two potentiometers allow set the desired flow rate and time period of the night cooling (bypass). The controller is connected to the unit by 10m by cable.

Frequently asked questions and answers

Decentral vs. central ventilation ???

Decentral ventilation is mechanical ventilation for one room only. Central ventilation is mechanical ventilation of more rooms by once device. Central ventilation is provided by units with bigger dimensions than units for decentral ventilation, since these has to supply higher air volume. Units for central ventilations are usually located in the technical room where they are not annoying the users by high noise level and they are not blocking any space. Central ventilation systems require ducting for supply and extract air, which are often difficult to place in the way to do not disturb. Central ducting systems require cleaning every year, which is complicated. Cost investment of the installation of ducting and theirs covers are usually in the same level as the purchase price of the ventilation unit. Another aspect is regulation and controlling of these systems in order to achieve minimum operation costs and distribution of the air to there where is needed. The advantage is, that suction and exhaust does not have to be located on the outside wall and if so, there are always only two openings. Decentral units are used for ventilation of one room only. Theirs dimensions vary from very small ones located in to the wall, to bigger ones with dimensions similar to smaller radiator. These units ventilate only selected rooms and when needed. Theirs advantage is, that these units can be operated according to sensors of quality of the air (Air Quality sensors -AQS), typically by CO2 sensor or relative humidity sensor. Thanks to the sensors the unit ventilates only when the concentration of pollution in the air is above set level – this means “ON DEMAND”. This ensure, that the energy consumption during ventilation is at minimum level, about 35% lower than ventilation without sensors. More powerful units can supply in to the room bigger air volume of the air in case of need than central units and thus can ventilate the room faster and better.

It is necessary to consider more suitable solution for each specific project.

How to choose right size of the unit ???

One of the mains parameters of the unit is the air volume which is the unit able to supply in to the room. Value which is usually used for choice, is quantity of the air at one square meter of the floor space. Manufactures usually used 25m3/h at 20m2. This is half quantity which ensure healthy climate. For the most cases are better to use quantity of the air need at quantity of the people inside the room. Typical value is 25m3/h/person.

It is important to choose higher value of both methods in specific case anyway.

Why sensors (air quality sensors) ???

Sensors enable automatic operation of the unit. The unit operates only, when the inside quality of the air is worse than requested. When fulfilling the air quality request, such a solution generate only minimum ventilation costs in the real operations! This also means lower operation costs and faster paid back of the investment to ventilation unit purchase. Xroom enables connection of CO2 sensor, RH sensor and radon sensor.

It is important to consider, if the more important are operation costs, or purchase investment.

What means enthalpic regeneration ???

Enthalpic regeneration (ERV) means backwards gaining of the moisture from the extract air. The supplied air is so dry in the winter, that it can reduce the indoor relative humidity in the air below 20%. Such a low relative humidity cause drying-off the skin, mucous membrane and wood- -made furniture and floors. Dry mucous membrane makes breathing less comfortable and cause respiratory diseases. Dehydration of the skin makes wrinkles and the drying-off the wood can damage furniture or floors. Ideal relative humidity inside should be around 50%. The solution is usage of Enthalpic Recovery Exchanger (Xvent recommends).

It is important to know that enthalpy heat exchangers always also recover heat.

Why is mechanical ventilation needed ???

Ventilation by windows is in many cases enough (residential areas, alone houses close to the forest), but does not ensure the energy savings (heat in the winter, cold during summer). But if there is noise outside, pollen, annoying smell or freezing conditions, the ventilation by window is not the best solution. Even thought in the summer, if the room is equipped by air conditioner, is the opening the windows not suitable. In all cases mentioned above is the mechanical ventilation senseful solution.
If the unit is equipped by heat recovery and/or moisture regeneration, the energy savings reach 85%, which will have to be supplied by heating or by cooling device otherwise.

It is important to consider if the priority is price or health.

What are the operation costs ???

thanks to the EC fans 1 EUR/month when considering average usage four hours a day every day.

Costs of filter replacement are around 10 EUR/month when replaced twice a year.
