VITA-P20 (200m³) Constant Volume Humidity Controller



Provide an uninterrupted, effective, gentle and sudden humidity control for single or multiple medium and large display cabinets and open cabinets.

Low energy consumption, stable air flow and high control accuracy.

All-steel frame and shell, durable, safe and reliable.

The output airflow reaches the set range before it is delivered to the showcase. If the airflow fails to meet the standard due to equipment failure or other factors during operation, the equipment will automatically switch to the bypass and no longer deliver to the cabinet to ensure the safety and stability of the airflow.

The positive pressure method sends the gas required by the cultural relics into the cabinet. At the same time, the air filter module is equipped to effectively prevent the polluted gas from entering the showcase.

The continuous positive pressure airflow can continuously squeeze out the volatiles in the cultural relics or showcases, making the environment control in the cabinets more stable and cleaner.

Purely physical adjustment, simple operation, reliable use and easy maintenance.

Perfect self-checking function, can prompt alarm for faults or abnormal conditions.

The equipment comes with a water tank and has an automatic water replenishment function, without manual intervention (the equipment needs to be connected to tap water).
