Comfort Fresh Air HRV - High-Efficiency Vertical Heat Recovery Unit with Top Ports

The new, compact model with top duct connections incorporates a counter-flow heat exchanger, offering superior energy recovery performance reaching up to 95%. Its internal structure is made of durable, heat-insulating EPP material, which houses quiet and highly efficient EC technology fans. Control is a breeze, as the system features a built-in panel on the machine's body and a remote control with 4 operating modes, including the practical By-pass mode. Moreover, it adapts perfectly to the needs of your space, as it is optionally available in a left or right configuration for completely flexible installation.

Creating a Healthy Microclimate

The Comfort Fresh Air (HRV/ERV) series ventilation units are designed to supply fresh outdoor air and create a healthy living environment, providing the space with oxygen and a comfortable temperature. The unit balances the intake of fresh air and the extraction of stale air, while the airflows remain completely separated and do not mix with each other.

Energy Efficiency and Economy

The heat from the extracted air is transferred to the incoming cold air via the heat exchanger, allowing the "free" heating of the outdoor air without wasting energy. The use of this system helps to reduce the size and power of the required heating and air conditioning (HVAC) equipment, as the load for heating and cooling is significantly reduced.

Innovative Materials and Durability

The internal structure is made of advanced EPP material, which is distinguished by its light weight, excellent heat retention, quiet operation, ecological composition, and absence of odors. Inside, it features a washable 3D cross-counterflow heat exchanger made of special resin and ABS plastic, with a lifespan of up to 15 years.

Heat and Moisture Recovery

The system offers top heat recovery efficiency reaching 95%. In addition, an enthalpy exchanger is available as an option, which recovers up to 80% of moisture, preventing air dryness in winter. This type of exchanger does not require condensate drainage and prevents ice formation even in extreme temperatures down to -30°C.

Absolute Air Purification and By-pass

Equipped with a dual filtration system, the unit captures 95% of dust. There is the option to add an F7 filter for protection against allergens and fine particles. At the same time, it incorporates a 100% By-pass mode, which is automatically activated based on the outdoor temperature, offering natural cooling in summer.

Smart Control and Flexibility

Control is done wirelessly via Wi-Fi and the Smart Life app, allowing you to monitor air quality (CO2, humidity, temperature) from your mobile. You can create smart scenarios based on weather conditions or connect multiple devices via Tuya IoT. The installation is also flexible, with a choice of left or right configuration (depending on the space), which can be modified on-site.

Useful Information & FAQ

What is an ERV system?

An ERV (Energy Recovery Ventilation) system continuously supplies your space with fresh, filtered air and removes stale air, without losing the valuable energy of heating or cooling. Through a special heat exchanger, the unit recovers heat and moisture, pre-heating the outdoor air in winter and pre-cooling it in summer. This process significantly reduces power consumption and takes the load off your air conditioners, always maintaining the ideal temperature at home. It is the perfect solution for modern, energy-efficient buildings, ensuring a completely healthy and comfortable living environment in the most economical way.

The Benefits of an ERV System

Stagnant indoor air degrades our quality of life, allowing viruses and harmful particles to accumulate. ERV systems directly address this problem by continuously replacing "stale" air with fresh and clean air. Additionally, they maintain the right humidity levels in the space, stopping mold growth and reducing allergens. The result is a truly clean, safe, and energy-efficient home, day and night.

Do I really need a heat exchanger?

The answer is "yes" if you are looking for fresh air without opening windows due to outside noise, exhaust fumes, or extreme temperatures. It is essential if you face humidity and mold problems due to inadequate ventilation, or if you suffer from allergies, needing an environment with continuously filtered, clean air. Finally, it is the ideal solution if you want to ventilate your space without losing the heat or coolness of your air conditioner, noticeably reducing energy costs. In these cases, installing it is not a luxury, but a substantial investment in the health and economy of your home.

Can I install it in an already inhabited home?

Yes, absolutely! Autonomous ventilation units are designed for easy installation without major renovations or complex piping. The process usually requires only drilling a hole in the outer wall and providing a power supply, making the installation fast and clean. It is the ideal choice for an immediate upgrade of the air quality in your bedroom, living room, or office, without disrupting your space.

Is maintaining a heat exchanger difficult or expensive?

Basic maintenance is extremely simple and you can do it yourself. All that is required is the regular cleaning of the filters (e.g., with a vacuum cleaner or water) and their periodic replacement depending on the pollution of the outside air. In this easy and economical way, you ensure the maximum performance of the device and absolute air cleanliness in your space for many years.

Do you handle the installation?

Yes! We partner with experienced technicians who can undertake the complete and safe installation of the heat exchanger in your space. You choose the ideal machine, and we connect you with our specialized partners for a flawless and guaranteed result, without any hassle.
