Our Work: Vacuum Storage of Pharmaceutical Products and Medical Supplies
A pharmaceutical manufacturer contacted us to build them a large vacuum storage system for their pharmaceutical products. They were looking for as much footprint as possible which is why they got a two-chamber system from us. They needed a total of 6 shelves per chamber including trays. Finally, they were looking to have both chambers to be placed on a table frame assembly with lockable swivel casters. What you are seeing is a two chamber system, each chamber is our 20 inch cube acrylic vacuum chamber, front load hinged door. Each chamber can be accesses independently while the other is under vacuum. The trays can be easily loaded and unloaded. This whole system can also be moved to anywhere in their facility.
