Installed as part of a “drive-thru” application, the RHV helps facilities improve productivity and safety by enhancing environmental control and security at the loading dock. With this interior dock configuration, trucks back up to the loading dock with their doors closed. When they are secured at the dock, the trailer’s security seal is broken and the doors are then opened into the building. This process ensures cold chain integrity, in addition to increased security. It is also quicker for loading/unloading because truck drivers don’t have to leave the cab.
