Lossnay Fresh Air Energy Recovery Ventilation

Optimise Indoor Air Quality and Maximise Efficiencies with Lossnay Fresh Air Energy 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.

After launching its first generation in 1970, Lossnay has evolved by always looking ahead of the air conditioning needs of the times, which continue to diversify. The technology is used in a wide range of applications and units have been widely adopted in residences, office buildings, hospitals, schools, etc.

The Need for Fresh Air

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.

Total Heat Exchange Ventilation Maximises Heating or Cooling Efficiencies

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.

Improved Airflow Range

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.

Low Noise Design

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

Improved External Static Pressure

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.

Weekly Timer

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.

Optimised Control with Optional CO₂ Sensor

Optimise airflow for each application with the new remote controller, PZ-62DR-E.

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.

Two types of CO₂ sensors are available: wall-mounted and duct-mounted types.
Power is supplied to the CO₂ sensor from the Lossnay board.

Fan speed automatically changes from 25% to 100% (16 steps) depending on the level of CO₂ concentration.

Both upper and lower limits can be adjusted.
Upper limit: from 600 to 2000 ppm.
Lower limit: from 300 to (upper limit - 300) ppm. 50 ppm increments.

Optional CO₂ Monitoring

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

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.

*Dual Barrier Coating is applied to Air Supply/Exhaust Fan

Upgraded Filters

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

Vertical installation

Using optional parts, the Lossnay RVX3 range can be installed vertically, expanding the number of installation possibilities.

Please follow the installation manual when you install the RVX3 series vertically.
