HPD

The Closed-cycle Solution for Special Gases

Our HPD series dehumidifying equipment have a closed-cycle, non-purge mechanism that does not release any compressed air into the atmosphere and can be used for processing toxic, flammable or rare gases. Closed-cycle dehumidifying equipment are super quiet since they do not release any air.
