"E" version: with enthalpy system heat exchanger, automatic bypass function (the possibility of ventilation without heat exchange, if necessary), with the Aerauliqa CTRL-DISP multifunctional control unit included with the device. By using a heat recovery ventilation device with an enthalpy system heat exchanger, the highest energy efficiency ventilation can be achieved without a decrease in humidity, therefore its installation in buildings with low humidity is recommended. In such a case, it is also advisable to choose the enthalpy system devices, which can be used to prevent certain health problems caused by dry air, such as e.g. dry eyes, scratchy throat. "A" energy efficiency class, central (centralized) heat-recovery ventilator, vertical arrangement, wall-mounted version that can be placed in basements, cellars, mechanical rooms. Suitable for continuous or intermittent operation, energy-saving, dust- and other pollutant-free ventilation of certain rooms of family houses, apartments, offices, max. In the case of a floor area of ​​182 square meters. The internal structure of the device was designed with EPP (expanded polypropylene) insulation, for high airtightness and thermal insulation properties. Its energy-saving EC motor and maintenance-free rolling bearings designed for a long life enable low-noise operation. The unit's backward-bladed radial fans have direct drive and dynamic balancing for quiet and vibration-free operation. The high-efficiency, mold- and bacteria-free membrane heat exchanger unit with an enthalpy system ensures the highest thermal efficiency in its category (max. 90%) and the appropriate management of humidity. The built-in polymer membrane made with antibacterial technology is mold and bacteria-free, and also prevents the passage of pollutants in the air and eliminates odors. The device is equipped with G4 filters that are easily accessible without tools, can be cleaned, and can be replaced if needed. Important features:- automatic frost protection control;- no need to create a condensate drain; - automatic balanced ventilation; - built-in physical bypass (the possibility of ventilation without heat exchange, if necessary); - digital control interface in Hungarian; - weekly programmability; - filter saturation indicator; - "Boost" rapid ventilation function; - "freedom" mode; - night (extra silent) mode;- check total operating time;- save and load settings;- can be expanded with sensors (steam, motion, CO2 sensor);- ModBus interface;- pre- or post-heating units can be connected to it. Ideal choice for those who save energy and they want to implement extremely quiet ventilation with high energy efficiency and parametrability according to user needs, in fully automated mode while keeping the humidity of the ventilated rooms at an appropriate value. ASSESSMENT, CONSULTATION, EXECUTION! Advantages of ventilation devices with a heat recovery function: Health and hygiene: - continuous and automatic air exchange - the concentration of certain "polluting" substances harmful to health does not increase in the apartment. respectively it cannot enter from the outside (formaldehyde, volatile organic compounds, etc.);- radon concentration can be kept at a low level,- mold formation can be prevented;- air of optimal quality and composition, allergen-free environment. Comfort: - a draft-free environment and lower temperature fluctuations; - adequate humidity; - an interior free of mosquitoes, flies and other flying insects; - noise level infiltrating from the outside can be kept at a low level; - an environment free of unpleasant odors; - automatic and extremely quiet operation. Energy certificate: - for the highest energy efficiency building and apartment ventilation, with an A or A+ energy rating. Safety:- damage caused by sneaking thieves taking advantage of the open doors and windows characteristic of traditional ventilation can be avoided. the costs associated with cooling can be kept at the same level; - environmentally friendly ventilation, extremely low environmental impact; - a heating system that can be designed and operated at lower costs; - in the case of newly built houses, walls with a higher moisture content dry faster, mold does not develop; - in some cases, tax credits and more favorable insurance conditions are available in accordance with local (e.g. municipal) regulations.
