Solvent Processing Using Stainless Steel Stations

Manufacturing processes using volatile solvents have to be specially designed to minimize the risk of explosions or fire. Solvents like acetone or alcohol are used to clean parts, dissolve materials and extract substances.

Safe stainless steel solvent operation depends on specific design measures that reduce the risk of fire or explosion. Modutek provides stainless-steel stations that meet strict safety regulations used in wet bench processing that reduce the risk of ignition of the solvents or their vapors. They have additional features and interlocks in an integrated approach to operator safety. Special safety design measures can include:

• Electrical equipment runs on low voltages and weak currents to reduce the risk from sparks.
• Electric wiring satisfies fire protection standards NFPA 70 and 79.
• Overall station design satisfies hazardous location standards and is certified for Class 1, Division 2 environments.
• The manufacturing process is monitored to detect dangerous conditions such as high temperature.
• Liquid solvent waste is collected in carboys for controlled disposal.
• Safety interlocks eliminate unsafe operation and shut down the process for unsafe conditions.
• Automatic lid operation can seal off chemical containers.
• Operators are trained for safe operation.
• Access controls limit equipment operation to trained personnel.

Modutek's Series SFa and Sa Stainless Steel Stations for solvent processing meet all safety requirements in the applicable regulations. Made of electropolished steel, the stations meet the National Electrical Code Class 1 Division 2 Group D standard for hazardous locations.

The baths feature PVC safety shields, N2 head case purge and an auto lid option. They are designed for operator safety and prioritize safe containment and disposal of volatile solvents. The SFa Series – uses a temperature-controlled re-circulating bath, while the Sa Series is constant temperature.

In addition to the safety measures and temperature control features, the baths have multi-sided heating elements, a 360-degree overflow weir, operating interlocks, process control thermocouples and liquid level sensors. The tanks are available in standard sizes and customized sizes.

Modutek has over 40 years of experience designing wet benches for semiconductor manufacturing. Aa a leading wet bench manufacturer, Modutek works toward advancements to their wet processing equipment, including those with solvent processing stations.
