50RVX3 Lossnay Fresh Air Heat Recovery Ventilation

As an energy reclaim mechanical ventilation system, Lossnay LGH-RVX3-E models are equipped with chemically treated paper core to recover sensible and latent heat from the outgoing stale air to pre-warm (or pre-cool) incoming fresh air.

The LGH-RVX3-E range allows buildings to maximise efficiencies whilst maintaining healthy CO2 and humidity levels for better indoor air quality.

Elevating air quality and maximising energy efficiencies has never been easier, because now the power is in your hands.

• See by how many degrees Lossnay is pre-warming or cooling your home in real time, helping you save on your power bill because less additional heating is required to get a room up to temperature.

• And in summer, monitor by how many degrees Lossnay reduces the average temperature in your home, using Automatic Free Cooling Mode.

• The app will also proactively remind you when it is time to clean your filters to maximise both cost efficient operation and health benefits.

Poor air quality can be attributed to many problems arising in the workplace and in the home. It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness. Providing good ventilation in residential and commercial buildings enables occupants to live and work comfortably and safely.

The key to Lossnay is the unique heat transfer core. Through the Lossnay Core, up to 88%* of the energy in the stale exhaust air is recovered and transferred to pre-warm (or cool) incoming fresh, filtered air.

For example, in winter a building that has an inside temperature of 20°C and 4°C air outside, the incoming fresh air can be warmed to over 18°C by transferring through a Lossnay Ventilation System and benefitting from the efficient energy transfer process. The building’s air conditioning systems no longer have to work as hard to maintain desired indoor air temperatures.

The default fan speed value (Fan speed 1: 25%, Fan speed 2: 50%, Fan speed 3: 75%, and Fan speed 4: 100%) of both supply air and exhaust air can be adjusted flexibly. Within the range between 25% and 100%, airflow can be adjusted by 5% increments to satisfactorily meet the designed airflow rate.

By providing a range of air volume for each fan speed, sound levels can be reduced to achieve low noise.

External static pressure has been improved compared to previous models. By increasing the external static pressure, highly flexible duct work becomes possible thus renewal from existing equipment is easy.

Optimise airflow for each application with the new remote controller, PZ-62DR-E†. The operation pattern for each day of the week, ON / OFF and air volume can be set using the weekly timer function (up to eight separate Start/Stop patterns per day over a 7 day period). Compared to previous models, much finer operation control contributes to enhanced energy saving operation. With a wider range of air volumes the Lossnay RVX units enable optimised ventilation not just at different times of the day, but for different days of the week as well, enabling further energy savings.

A Mitsubishi Electric CO2 sensor connected directly to the LGH-RVX3-E unit optimises the fan speed according to the levels CO2 detected, ensuring indoor air quality is maximised and total heat exchange efficiency is improved. There are two sensor options available, a wall mounted type or built-in.

With the option of an additional CO2 sensor. When connected with the optional Wi-Fi Control Interface, CO2 levels can be viewed in real-time making it ideal for schools, medical facilities and offices.

It is well known that poor air quality impacts health, wellbeing and concentration levels. In conjunction with the CO2 sensor, the Lossnay LGH-RVX3-E system intuitively adjust airflow to ensure optimum air quality, no matter how many people are in the room.

Dual Barrier Coating prevents dust and oil build-up on the interior of the Lossnay unit, helping to keep it clean for optimal performance. A water-repellent effect is achieved by creating a coating film that has nano-sized concave-convex structures formed by silica nanoparticles made of water-repellent fluororesin and micron-sized concave-convex structures formed by combining micronsized special-shaped particles (silicate) with the silica nanoparticles. At the same time, the uneven structure forms an air layer that suppresses the adhesion of dust and sand that contain a lot of humidity, reducing the amount of dirt that adheres to the substrate.

The standard filter has been improved from Coarse 35% to Coarse 60% (measured by ISO16890: 2016).
