Pevco Smart Seal, a heat seal bagging system integrated within a pneumatic tube station, helps guard against spills and protect fragile pneumatic tube cargo. Simply place items into the single-use Pevco Smart Seal bag, and slip the top of the bag between the heat-sealing guides. Smart Seal holds the bag in place until the four second heat-seal process is complete, eliminating spills that may contaminate the system. UL-listed and engineered to withstand the demanding health care environment, Smart Seal units can be installed within a tube station or on a countertop.
