Swegon CASA ERV · Thailand
Fresh, filtered air — designed for Thailand’s hot & humid climate
CASA Sorption combines balanced whole-home ventilation, fresh-air filtration, energy recovery and high humidity recovery in one intelligent system. It reduces the heat and moisture load in incoming outdoor air before it reaches the home — helping create a cleaner, more stable and comfortable indoor climate.
Engineered for Thailand
Our residential approach is simple: filter the outdoor air, recover energy and moisture with CASA Sorption, then add Comfort Cooling only where the project needs additional cooling or dehumidification.

The Thailand advantage
Moisture Management with CASA Sorption
Thailand’s fresh air is also humid air. CASA 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.
For Ventpro, Sorption is the first stage of humidity control. If a home needs lower supply-air temperatures or tighter RH control, Comfort Cooling / active dehumidification can be added 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.

CASA Genius
Monitors and adjusts ventilation automatically.
Comfort Cooling
Add active cooling / drying only when needed.
Thailand design logic: reduce the moisture load with Sorption first, then use active cooling/dehumidification for the remaining project requirement.
Complete residential indoor climate
CASA is the heart of the system — Ventpro designs the whole air path
The ERV is combined with filtration, ductwork, silencers, diffusers, extract terminals, controls and optional cooling/dehumidification to form the complete residential ventilation solution.

Treat the outdoor air before it enters the home
Ventpro residential solutions
Choose the indoor-climate solution that fits your home
Every home does not need the same level of cooling or filtration. Ventpro builds the residential system around the same CASA Sorption foundation, then adds the air-treatment level the project actually needs.
The important point: these are system solutions, not different CASA products. The CASA model is selected separately from the required airflow and installation format. The solution level defines how much cooling and filtration is added around the CASA unit.
CASA product range
Choose the airflow and installation format
For Thailand, Ventpro selects the CASA model from the required airflow, installation space, standard or horizontal format, duct routing and whether the project also needs active Comfort Cooling.
