Heat Exchange Ventilation & Normal Ventilation

Adopts a highly efficient counter-flow heat exchange element


Heat Exchange Ventilation

When a room is cooled or heated, the exhausted cooling / heating energy is recovered by heat-exchange ventilation.


Normal Ventilation

This is used in the spring and autumn, when rooms are not cooled or heated, that is, when there is little difference between the indoor and outdoor air conditions. In addition, at night during the hot season, when the outside air temperature drops the outside air is drawn inside without heat exchange, alleviating the load on the air conditioning equipment.

High Efficiency

Energy Efficiency and Ecology

Energy consumption is dramatically reduced by using a counter-flow 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.

Features of Heat Exchange Element

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.


Design Flexibility

Extended Range of an External Static Pressure

An external static pressure is improved by adopting a powerful fan motor.

This allows for application in a wide variety building.


Easy Installation & Maintenance

Slim Shape and Easier Installation

Counter-flow heat exchange element used for reduced noise and slimmer, more compact body shape.

Reverse Mountable Direct Air Supply / Exhaust System

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.
