Thailand has a hot and humid climate, and underground spaces are especially prone to moisture problems. Underground garages, basement parking areas, equipment rooms and underground storage spaces often require dedicated dehumidification and ventilation solutions to maintain a drier and more comfortable environment.
This case study shows how a dehumidification solution can be applied to an underground garage project in Thailand.
Location: Thailand
Application: Underground garage and basement parking area
Solution Type: Underground space dehumidification
Recommended Product Series: Cycair DMC-A Series and DCM-A Series
Alternative Product Options: DP-E Series, DP-F Series
Key Requirements: Moisture control, condensation reduction, continuous drainage, strong airflow and reliable operation in humid climate
Underground garages are naturally more humid than above-ground spaces. In Thailand, outdoor air is often warm and humid, and moisture can enter underground areas through ramps, ventilation openings, vehicles, walls and floors.
Because underground garages have limited natural ventilation and cooler surfaces, condensation may appear on walls, ceilings, pipes or floors. The space may also develop damp air and musty smell.
The project required stable moisture control in a large underground parking area.
Common challenges included:
Ventilation was important, but ventilation alone could introduce more humid outdoor air during some seasons.
The underground garage needed:
Cycair recommends combining industrial dehumidification with proper ventilation planning.
For large underground parking areas, DMC-A Series Floor Standing Industrial Dehumidifiers can provide high-capacity moisture removal and strong airflow.
For fixed installation or areas where floor space needs to be saved, DCM-A Series Ceiling Mounted Dehumidifiers can be considered.
For local moisture problems, temporary control or flexible use, DP-E Series and DP-F Series Industrial Portable Dehumidifiers can support specific zones.
For large underground garages, DMC-A480L, DMC-A600L, DMC-A960L or DMC-A1440L may be considered depending on the space size and moisture load.
For underground storage rooms, equipment rooms or concealed installation zones, suitable models from the DCM-A Series can be selected based on airflow and capacity requirements.
The final recommendation should be based on parking area size, ceiling height, humidity level, drainage conditions, power supply and airflow layout.
A well-planned underground garage dehumidification system helps improve the indoor environment and reduce moisture-related problems.
The solution can support:
In humid climates such as Thailand, underground spaces need more than natural ventilation. Dehumidification directly removes moisture from the indoor air, while ventilation supports air exchange.
The combination of industrial dehumidifiers and suitable airflow design helps create a more stable underground garage environment.
