What is the MDC?

The MDC is a self-contained, mobile unit designed to dry plastic resin and convey it with dehumidified air directly to a processing machine. This mobile unit contains the:

•Dehumidifying dryer

•Drying hopper and material distribution box

•Conveying blower and dust collector

•Mobile drying cart

•Direct feed vacuum receiver and demand sensor

•Quick disconnect conveying hoses

The dryer produces hot, low dew point air that removes moisture from hygroscopic plastics. When the conveying function is turned on, the conveying blower conveys the dried resin to the vacuum receiver mounted on the processing machine. The demand sensor on the vacuum receiver viewing chamber allows you to convey just enough material to satisfy the shot size required for your process.

Central

When configured as a central dryer, the MDC option is not available.
