The transfer trolley is used for the storage and the transfer of products that are sensitive to contamination, between two class A areas, and through a class C area.
Working principle
A laminar air flow class ISO 5 ( ISO 14644-1) is blown horizontally from the blowing plenum, towards the loading door, thus swiping the area where the products are stored (shelves and trays), and maintaining a positive pressure within the transfer trolley greater than the pressure in the surrounding room, thus avoiding any cross contamination. The transfer trolleys are equipped with a system of electrical plug / embarked battery UPS, that maintain the laminar flow conditions in the transfer trolley at all times. The battery level is monitored via a charge indicator.
