Heat exchange ventilation and normal ventilation
Heat exchange ventilation
When a room is cooled or heated, the exhausted cooling / heating
energy is recovered by heat-exchange ventilation.
Normal ventilation
The operation is used during periods when the room space requires
no cooling or heating effect, i.e. when there is minimal temperature
difference between the indoor and outdoor environments.
Adopts a highly efficient counter-flow

Slim shape and easier installationEnergy efficiency and ecology
Features of heat exchange element
Quiet operation
Extended range of an external
static pressure
Reverse mountable direct air supply /
exhaust system
Energy consumption is dramatically reduced
by using a counterflow heat-exchange
element. Air conditioning load is reduced by
approximately 20%, resulting in significant
energy savings. Recovers up to 77% of the
heat in the outgoing air.
Counter-flow heat exchange element used for reduced noise and
slimmer, more compact body shape.
Adoption of straight air supply / exhaust system: Duct design
is simplified because the air supply / exhaust ducts are straight.
Since each unit can be mounted in reverse position, only one
inspection hole is needed for two units: Two units can share
one inspection hole so duct work is easier and more flexible.
With the cross-flow element, air moves in a straight line across the
element. With the counter-flow element , air flows through the
element for a longer time (longer distance) ,so the heat-exchange
effect remains unchanged.
Significantly reducing low pressure loss and noise allows low-noise
operation.
An external static pressure is improved by adopting a powerful fan
motor.
This allows for application in a wide variety building.
