Vacuum

Modern, energy efficient Steam Ejector Systems offer many advantages when compared with other vacuum producing systems. They can also utilise motive steam which is already available on site and would be otherwise wasted.

Advantages

• The most reliable of all high vacuum systems
• Ideal for large loads
• No moving parts
• Simplicity
• Low noise levels
• Minimal and non-specialist maintenance
• Custom designed
• Easy to retrofit or uprate
• Process guaranteed
• Available in any workable material
• No ATEX considerations

Materials of Construction

For non-corrosive applications Stainless Steel, Carbon Steel or Cast Iron are most commonly used.

Condensers

Direct Contact and Indirect Contact Condensers are available for either barometric or low level operation. The Indirect of Surface Contact Condenser is used when the Ejector fluid and cooling medium must be kept separate, whereas the Direct Contact Condenser is used when the complete mixing is acceptable.

Transvac has considerable experience in supplying corrosion resistant Vacuum Systems. They are ideal for Fine Chemical and Pharmaceutical applications by virtue of their reliability, simplicity, low capital cost and low maintenance.

Advantages

• Handles Large Volumes of gas
• The most reliable of all high integrity vacuum systems.
• Handles slugs of liquid/particles without damage
• No moving parts
• Low noise levels
• Less expensive than mechanical pumps
• No ATEX considerations
• Simplicity and low maintenance
• Custom designed for low and high vacuums
• Easy to retrofit or uprate
• Overheating not a problem

Materials Of Construction

Steam Ejectors can be constructed from exotic materials including PTFE, PVDF, Hastelloy, Graphite, Monel, etc. Indirect Contact Condensers are usually constructed from Graphite and Direct Contact Condensers from PTFE lined Carbon Steel or PVDF.

Transvac offer a complete range of fully instrumented low level skid mounted systems, versatile in handling both wet and dry loads. Designed to user specifications and offering clear energy savings.

Systems are available with one, two or three stages of Steam Ejectors combined with a single or two stage Liquid Ring Vacuum Pump. The Liquid Ring Pump is very effective at rapidly producing a coarse vacuum and the Steam Ejectors are used to create higher vacuum levels.

Advantages

• Reliable with only one moving part
• Energy efficient
• Operates with very low steam pressures
• Low level operation
• Simplicity
• Low noise levels
• Custom designed
• Easy to retrofit or uprate

For batch plant applications requiring coarse vacuum and low level installation.

With the liquid recirculating pump being the only moving part the Liquid Jet Exhauster System is simple to maintain and very reliable to operate.

The ability to produce vacuum and simultaneously scrub entrained gases before discharge to atmosphere makes the system ideal for contaminated and/or corrosive applications.

Available in multi-element form as a central vacuum source on multi-purpose process applications.

Advantages

• Reliable with only one moving part
• Scrubs outlet gases
• Handles liquids/particles without damage
• Energy efficient
• Low level operation
• Simplicity
• Low noise levels
• Custom designed Materials to suit process fluid

A Thermocompressor can be described as a type of Jet Ejector that uses a jet of high pressure steam (called the motive fluid) to entrain low pressure steam (called the suction fluid). The two fluids become intimately mixed and are subsequently discharged at a pressure that lies somewhere between that of the motive and suction conditions.

For applications with varying operating conditions Transvac offers a variable nozzle design to ensure efficient performance is maintained over the range of desired operation.

Transvac atmospheric air jet ejectors can be combined with liquid ring pumps to increase their ultimate vacuum levels.

Pressurised air jet ejectors can be used on their own for vacuum transfer of fluids and similar coarse vacuum applications.

Advantages

• No additional energy source needed (atmospheric air)
• Ideal for retrofitting on small load duties
• No moving parts
• Reliable
• Simple to operate
• Materials to suit process
• Custom designed
