How Energy Recovery Ventilators Work:

How Energy Recovery Ventilators Work:
In the RenewAire (formerly Lossnay) energy exchange core, the exhausted stale air and the fresh ventilation air pass through multiple air passages separated by an engineered composite resin partition plate. Sensible heat transfers from the warmer to the cooler air stream. Also, latent energy (water vapor in the gas state) transfers from the wetter to the drier air stream. The fresh incoming air is automatically preheated or precooled depending on the season. This dramatically reduces the energy costs of ventilation.
This unique moisture transfer feature of the RenewAire (formerly Lossnay) energy exchange core eliminates condensate and frosting in most applications. No mechanical or electrical defrost systems are needed, which means higher heat recovery efficiencies, simpler installation and more reliable operation.

During the Heating Season:
Outdoor air is warmed to close-to-room temperature with heat that would otherwise be lost with the exhaust air. Indoor humidity levels are prevented from becoming too dry or too humid by the partial transfer of water vapor. Non-enthalpic heat recovery systems cannot deliver that benefit.


During the Air Conditioning Season:
RenewAire (formerly Lossnay) Core systems recover coolness and dryness from the exhausted air. Outside air brought in for ventilation is reduced in temperature and humidity because its heat and humidity is transferred to the exhaust air stream.
With summer-time humidity (latent load) being the largest portion of the cooling load associated with outside air ventilation, this humidity transfer is critical. Other plate-type heat exchangers can’t touch this major load. RenewAire (formerly Lossnay) makes it easier for your air conditioning system to keep you both cool and dry.

No condensate pan or drain for easier installation and no associated biological growths.


Summer: Reduced cooling load on the air conditioning equipment.
• Moderates humidity extremes associated with outside air ventilation.


Year
Round: Reliable fixed plate design versus heat wheel, heat pipe, metallic or plastic fixed plate alternatives.
• Low maintenance, no moving parts
• expandable designs for unlimited CFM
• 10 year energy exchange core warranty
• Proven in all climates
• Simple and easy to control

RenewAire (formerly Lossnay) ENERGY RECOVERY VENTILATORS ARE available in a wide range of sizes and configurations to suit virtually any application form residential to applied-commercial to institutional. Since its introduction in 1970, the RenewAire (formerly Lossnay) Core has provided energy-efficient ventilation in thousands of systems throughout North America and around the globe. In fact, more RenewAire (formerly Lossnay) Cores have been used in energy recovery ventilation systems than any other core in the world.

RenewAire (formerly Lossnay) ERVs SAVE UP TO seventy-five percent in energy costs
The RenewAire (formerly Lossnay) energy recovery system saves money by reducing the workload on your heating and cooling equipment when bringing in fresh air. The equipment can then be smaller than you would have to buy if you were using other types of ventilation equipment. In fact, you’ll save up to 75% in energy compared to typical ventilation systems, resulting in lower utility bills in both the heat of summer and the cold of winter.
