This integrated system provides controlled heating and vacuum cycling of pharmaceuticals in multiple vacuum/nitrogen ovens.
A sequence controller allows programming of up to 999 heating/vacuum cycles in up to 9 processing chambers. Each 1600W process oven is rated for 220°C heating and includes a high-limit thermostat to protect against overheating that could cause sublimation in chemical drying applications. Vacuum control modules for each chamber control pump operation to maintain the desired vacuum level (to 29.9" Hg). A refrigeration/condenser module reclaims vapors from the vacuum line to ensure trouble-free pump operation.
A process gas controller backfills the heating chamber with a N2/CO2 gas mixture to ensure a clean, nonreactive drying environment. A Nitrogen Generator produces a continuous flow of 99.9% pure nitrogen from a compressed air feed for use in facilities without high-volume N2 supply.
