Poor air quality can be attributed to many
problems arising in the workplace or in the
home. It is believed to contribute to a
significant loss in productivity, low morale and
higher rates of sickness among many
employees. The object of providing good
ventilation alongside air condition in
residential and commercial buildings is to
provide conditions under which people can
live and work comfort and safety.
Developed and refined over the past 30
years, the LOSSNAY system has perfected
the recovery of waste energy. The units
reduce overall energy costs by extracting
stale air and then recovering the heating or
cooling energy to either warm and cool
incoming fresh air. By utilising this energy, the
LOSSNAY system can save up to 30% on
initial capital costs of heating and cooling
plant.

Every building needs a supply of fresh air to keep its inhabitants healthy and comfortable. Outdoor air though is rarely, if ever,
the same temperature as that maintained by the building
,
s air conditioning system. In the summer, it is too hot. In the winter, it
is too cold. This puts added stress on the air conditioner to compensate for the intake of the hot or cold air adding to the
expense of operating the system. LOSSNAY all but eliminates this problem with original energy-recovery technology that uses
the heat of the stale indoor air to be expelled in order to either heat or cool the incoming fresh air to a temperature much closer
to the existing indoor air. This process reduces the load on the air conditioning system without cutting off the supply of vitally
necessary fresh air.
The remarkable technology that permits the intake of fresh air with
minimal loss to indoor temperature is know as the LOSSNAY
Core. The cross-flow, plate-fin structure of the energy-recovery
unit along with a specially processed diaphragm keep supply and
exhaust air separate, ensuring that only fresh air is introduced to
the indoor environment while also allowing for the efficient transfer
of heat.
The microscopically small pores of the diaphragm have been
made even smaller, decreasing the rate at which water soluble
gases such as ammonia and hydrogen pass through. Further, a
new specially processed paper used to make the diaphragm has
been developed with high moisture permeability characteristics
that aid in the transference of moisture for improved energy
exchange efficiency. These developments further improve
moisture permeability and effectiveness in shielding unwanted
gases, resulting in a lower rate of gas transference and more
highly efficient energy transfer.
