Introducing – the Vertical Lossnay Range

Mitsubishi Electric has launched the next generation of Whole Home Fresh Air Heat Recovery Ventilation that does not require installation in the attic. While exposed ceilings are great from an architectural aesthetics perspective, it limits the ability to install a traditional roof based ventilation system.

Designed for Flexibility and Convenience

The Vertical Lossnay Range is designed specifically for the New Zealand housing market and makes energy efficient, super-quiet ventilation accessible to even more homes.

Vertical Lossnay Units, VL250, 350 and 500

Because of the slimline, vertical upright design, the Lossnay Ventilation System is not limited to an in-roof installation. With its small upright footprint it can be placed in the garage or a cupboard in the kitchen. Now whole home ventilation can be installed without compromising the architectural design of the building.

Automatic Summer Bypass

Using the on-board temperature sensors, the Vertical Lossnay unit automatically enters Bypass Mode when it detects a space is hotter than desired and the outside air is cooler.

To reduce the risk of overheating the home, fresh air is introduced, bypassing the Lossnay Core. This is ideal for cooling down a dwelling that may have overheated during the day once the outside temperature has dropped in the evening.

Easy to Use Control

A built-in LCD controller allows for easy control and commissioning of the unit. This interface displays all functionality and temperature settings of the system.

Slimline to Fit in a Cupboard

The vertical upright design of the Lossnay Ventilation System is not limited to an in-roof installation. Now whole home ventilation can be integrated into the overall building design without limitations.

Make Heat Recovery Ventilation Visible – with Advanced Lossnay Wi-Fi Control

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.

Lossnay Wi-Fi Control truly is the smart evolution in fresh air ventilation.

^*The following compatible Lossnay models can be connected to the Wi-Fi Control Service via a compatible Wi-Fi Interface MAC-588IF-E: VL-250/350/500 Vertical, LGH-RVX-E-1 and LGH-RVS-E Series only.

^†The outside ‘Fresh Air’ and the inside ‘Avg Temp’ air temperatures are measured by the built-in sensors that are centrally located in the main Lossnay Ventilation unit.

The 4 Functions of the Lossnay Core

The Balanced Pressure Lossnay Heat Recovery Ventilation System removes stale, dirty air and draws in fresh air from outside. Lossnay also recovers heat energy from the air being transferred to pre-warm (or pre-cool) the fresh air being drawn into your home. Lossnay is ideal for small to large sized homes between 52m² and 400m².

The stale air extracted from your home is Return Air (RA). Return Air can contain high levels of CO₂, odours and other pollutants. This Return Air stream also contains heat energy that Lossnay can recover, which is not the case with positive pressure ventilation systems.
As the stale Return Air is removed, the Lossnay Core ‘recovers’ the useful heat energy from it. The air is then exhausted (EA) outside along with the unwanted pollutants.
Outdoor Air (OA) is introduced to provide fresh air. It is first filtered, then passed through the Lossnay Core. This allows it be pre-heated in winter (or pre-cooled in summer) using the energy recovered from the Return Air.
Supply Air (SA) then enters your house as fresh pre-heated or pre-cooled air.
