Waste Drum Cabinet
JST Drum Cabinets
JST’s drum cabinets can be configured in a variety of ways to safely handle chemistry to and from the process baths in a Workstation. The cabinets are sized for 30 or 55 liter drums and designed to hold one or multiple drums. The drum cabinets are manufactured from FM4910 material, meet SEMI S2 guidelines, and carry the CE Mark. Solvent Drum Cabinets feature double-walled construction and incorporate CO2 Fire Suppression. Facility inlets and outlets have NPT couplings for plumbing double-wall piping between the drum cabinets and the Workstation.
Waste Drum Cabinets
Waste Drum Cabinets are located remotely from the Workstation and collect used chemistry for bulk disposal using drums when waste chemistry facility drains are not available.
Pneumatic Pump and Liquid Level Monitoring
In facilities where no gravity feed line to the drum cabinet is provided, a pneumatic pump within the Workstation drains chemistry from the process bath to the Waste Drum Cabinet. Liquid level sensors send status signals to the front control panel showing waste chemistry volume by percentage. Near full and full status alarms are preset.
Near full percentage signals the need to change the drum. The full percentage level interlocks the pneumatic pump until a new drum is installed and the reset condition is met. Full liquid level audio alarm is optional.
Dual Waste Cabinets
Dual Waste Cabinets are configured to hold two drums and automatically switch over to the second drum when the first becomes full.
