Chemical Delivery Systems

A drum system typically uses 55-gallon drums positioned near the wet process station for direct delivery, while a tote system uses larger intermediate bulk containers fitted with a load-cell interface. Totes hold much greater volume, so they reduce how often containers are changed in high-consumption processes, while drums suit lower-volume or space-constrained installations.

The system can be configured for a wide range of process acids, solvents, and other wet process chemistries. Wetted components are built from Teflon and other chemically compatible materials, so the same platform can handle aggressive acids or high-purity solvents, provided the fluid path and seals are specified for the chemistry in use.

Purity is protected by an all-Teflon fluid path and a closed transfer route from the sealed container to the point of use. Because the chemical never sits in an open container or comes into contact with incompatible materials, the system avoids particle pickup, metal contamination, and evaporation losses that occur with manual pouring.

Yes. Digital I/O communication enables the system to exchange signals with the process tool and the building management system, so that delivery can be tied to bench operation and facility monitoring. This allows the system to be added to existing wet-processing equipment rather than requiring a full-line replacement.

Because the system relies on a pneumatic pump and few moving parts, routine maintenance is limited to periodic inspection of seals, fittings, and the pump, along with verification of the leak-detection and level sensors. Data logging supports this by tracking usage and flagging anomalies before they cause downtime.
