CASA R5
Sorption humidity recovery
Compact whole-home ventilation for medium-size homes and apartments, combining balanced fresh air, Sorption energy and humidity recovery, and intelligent CASA Genius controls.
Engineered for Thailand
Fresh air with the humidity load reduced first
CASA R5 Sorption recovers energy and moisture before the incoming fresh air reaches the rooms. Ventpro then adds filtration, air distribution and — where the project requires it — Comfort Cooling / active dehumidification.
Airflow range
30–117 L/s
Air volume
108–421 m³/h
Duct connections
4 × Ø160 mm
Format
Standard R
Final unit selection is based on design airflow, external pressure, duct layout, occupancy and the exact Thailand product configuration.
Why CASA R5
Whole-home fresh air and humidity recovery in a compact unit
CASA R5 is designed for medium-size homes and apartments that need continuous filtered fresh air, balanced extract ventilation and smart humidity management without a large plant room.
The Thailand advantage
Moisture Management with CASA R5 Sorption
Thailand’s fresh air is also humid air. CASA R5 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.
