All Steam Jet Vacuum Systems

An All Steam Jet Vacuum Has the Following Characteristics:

Advantages:

• No Moving Parts, simple operation, low maintenance, high reliability, handles vapors and some particulates
• Small and large sizes available, suction connections regularly to 24" dia., some up to 48" dia.
• Large design suction pressure range, typically from 0.3 mm HgA to atmospheric pressure
• Most corrosion resistant systems choice with many materials of construction available (316 SS, Hastelloy, graphite)
• No electricity, no ignition sources, no lubrication
• Used for reactors, dryers, evaporators, strippers, distillation columns, filters
• Lowest first cost

Disadvantages:

• Requires plant steam be available
• Steam condensate is mixed with the process material for disposal and must be removed from a vacuum space
• Can back flow steam condensate into process suction line if shut down improperly
