Abstract:
A chemical delivery system (500) which utilizes a purge technique which may utilize a variety of combinations of a medium level vacuum source, a hard vacuum source, and/or a liquid flush system (506). Also a chemical delivery system is disclosed that may be provided with a heater system for heating the chemical delivery system.
Abstract:
A bulk chemical delivery system, comprising: a bulk chemical canister that is connected to at least one manifold box, wherein each manifold box has at least two output lines, wherein each output line connects to a secondary canister. In non-limiting representative example, the bulk chemical canister may have a capacity of 200 liters. Also disclosed are novel manifolds for use in delivering chemicals from canisters and a transportation/containment cart.
