Improving underground environment: Subways are typically underground where humidity is higher. Rotary dehumidifiers can lower humidity and improve environmental comfort.
Protecting facility equipment: Preventing damage to electrical equipment, tracks, etc., caused by moisture, extending their lifespan.
Ensuring operational safety: Reducing interference from moisture on signal systems, ensuring the safe and reliable operation of the subway.
Enhancing passenger experience: Providing passengers with a relatively dry and comfortable traveling environment.
