In the panorama of air-conditioning and indoor air quality solutions, INNOVA presents HRA-i PLUS, a state-of-the-art compact unit that incorporates the most advanced technologies to ensure well-being, healthiness and sustainability in residential and hospitality environments.
This all-in-one unit is able to heat, cool, dehumidify, ventilate, filter and recover heat in both passive and active modes, also offering a free cooling function. HRA-i PLUS is therefore a complete and efficient answer to the needs of modern low-energy buildings.
Thanks to its ability to constantly renew indoor air without the need to open windows, the system helps maintain a healthy environment with filtered, oxygen-rich air, while eliminating carbon dioxide, fine dust, odours and volatile organic compounds. In addition, it uses the energy contained in the exhaust air as a source to power an internal heat pump, heating or cooling rooms efficiently, with the correct degree of humidity and significant energy savings when outside conditions allow.
The HRA-i PLUS provides an air flow rate of up to 460 cubic metres per hour, with three operating modes that intelligently adapt to room conditions: it can operate in renewal-only mode, when the desired temperature is already reached, in air-conditioning-only mode, when the temperature needs to be changed, or in combined mode, renewing air while providing heating or cooling, all with constant monitoring of environmental parameters.
Installation flexibility is another distinguishing feature of the product. It is available in a horizontal version, with a height of only 260 mm, ideal for installation in false ceilings or ceilings, or in a vertical configuration, perfect for wall installation, inside cabinets or cavities. This versatility makes HRA-i PLUS suitable for both renovations and new buildings with high energy performance, but also for hospitality contexts such as hotels and residences, where it can air-condition rooms and mini-apartments offering comfort similar to that of a centralised hydronic system, with the added advantage of air exchange.
The compact design allows for strategic installation with respect to the path of the ventilation ducts, while the centrifugal fans with high-efficiency brushless motors automatically adjust their speed according to the pressure drop, maintaining silence and low consumption. The absence of hydronic or gas piping is a further element of simplification compared to traditional systems.
The system integrates sensors for constant monitoring of air quality, detecting CO₂, VOC, temperature and humidity. Based on the data collected, it adjusts the ventilation to ensure optimal conditions at all times. The ePM1 80% filters on the air intake, recirculation and exhaust are easily replaced without tools. The two-stage heat recovery, with a static and a thermodynamic component, achieves a sensible efficiency of 86.8%. Heat treatment is provided by a silenced DC inverter compressor and an electric heater for post-heating, making air-conditioning possible with only the power supply.
Finally, the system is completed by the INNOVA M7 series wall control, an elegant, ultra-flat and intuitive interface designed to be installed in a standard flush-mounted electrical box. Equipped with an auto-brightness display and highly sensitive touch controls, this interface allows simple and precise management of room comfort.
With HRA-i PLUS, INNOVA offers a complete, intelligent and sustainable air treatment solution, ideal for those looking for a compact, silent and high-performance system capable of guaranteeing well-being and healthiness in every season.
