Why CASA R9
High-airflow whole-home ventilation for large residences
CASA R9 is suited to large homes that need higher ventilation capacity, more zones or longer duct runs while keeping the system balanced and automatically controlled.
The Thailand advantage
Moisture Management with CASA R9 Sorption
Thailand’s fresh air is also humid air. CASA R9 Sorption transfers both energy and moisture between the extract air and the incoming fresh air, helping reduce the humidity load before the air enters the home.
Humidity recovery can reach up to 80% . During hot and humid conditions, this helps keep indoor humidity more stable, reduces the load on the air-conditioning system and supports a cleaner, more comfortable indoor environment.
Sorption is the first stage of humidity control . If the home needs lower supply-air temperature or tighter RH control, Ventpro can add Comfort Cooling / active dehumidification after the CASA unit.
Up to 80%
Humidity recovery with CASA Sorption.
≈15–20%
Lower summer indoor humidity under suitable operating conditions.
Less load
Less moisture for the active cooling system to remove.
Performance varies with outdoor conditions, airflow, building characteristics and system operation.
Thailand moisture management
How Sorption stabilises indoor humidity
What the graph shows: the Sorption rotor keeps the indoor humidity curve substantially lower and more stable through the hot and rainy seasons.
