All of our Lossnay and RenewAire energy recovery ventilators are designed using
the patented Mitsubishi Lossnay Core.

The Lossnay and RenewAire systems consist of 3 major components: the Exhaust Air Fan, the Supply Air Fan and the Lossnay Core.

The Exhaust Air Fan draws stale indoor air through the Lossnay Core and discharges it outdoors.

The Supply Air Fan draws fresh outdoor air through the Lossnay Core in the opposite direction and releases it into the building.

Inside the Lossnay Core, both temperature (sensible heat) and humidity (latent heat) is exchanged from one air stream to another. Temperature is transferred by conduction, while humidity is transferred via hydroscopic resin transfer.

The word “Lossnay” originated from the Japanese word “Loss-Nai”, meaning “No Loss”. Our advanced Lossnay systems extract stale air and replace it with fresh air, saving energy in the process with their very effective heat energy recovery transfer.

This technology recovers most of the energy from the outgoing air thereby cutting the power consumption of cooling and heating systems by 45% to 75%. This is made possible by using special plate-fin epoxy treaded diaphragm heat exchanger, which enables maximum recovery of the latent energy (moisture) between airstreams.

These enthalpic recovery systems recover both sensible (temperature) and latent (moisture) energy with no moving parts using the Mitsubishi Lossnay™ Core. This provides superior energy transfer between airstreams while keeping moisture out in the summer and inside (in moderation) in the winter.

Since less energy is required to lower the temperature of dry air compared to moist air, Lossnay can reduce the load on the air conditioner and save you money. In addition, it also reduces the need for humidifiers in winter or dehumidifiers in the summer.

In addition to tremendous energy savings, perhaps the greatest benefit is the new-found comfort of fresher, cleaner and healthier air.

Unlike most HRVs which only exchange sensible energy (temperature), Lossnay Energy recovery ventilators also exchange latent energy (moisture). In addition to increased energy recovery, it also provides more control over moisture levels, which can be an important consideration depending on the local climate.

Where winter climates are extremely dry, Lossnay can recover moisture that would be exhausted to the outdoors by HRVs. This allows Lossnay to maintain a comfortable humidity level and avoid static electricity, sore throats and other discomforts caused by air that is too dry. It also reduces humidifier needs.

During the air-conditioning season, Lossnay can keep excess humidity and heat outdoors by extracting it from the incoming fresh air and transferring it to the stale exhaust air. This makes for more comfortable living conditions and since dry air requires less energy to cool than humid air, the demands and cost of your air conditioning and dehumidification systems can also be significantly reduced.

Lossnay is the world’s only ERV which is designed to have alternative direction for duct connection. Outdoor ducts can be installed either parallel or perpendicular to indoor ducts, resulting in increased installation flexibility which can result in significant installation savings.

Lossnay uses small diameter air ducts which fit into the limited space of the plenum perfectly, thus reducing material costs.
