Vacuum Systems

From single-stage steam jet ejectors through multi-stage condensing systems, hybrid configurations, and liquid ring vacuum pumps, Artisan designs and manufactures vacuum systems for the full range of industrial vacuum requirements.

Overview

Industrial Vacuum Systems, Engineered to Your Process.

Vacuum systems play a critical role across a wide range of industrial applications, from thermal separation, distillation, and evaporation to air removal, priming systems, and vacuum cooling. Each application enables lower operating temperatures, faster cycle times, or process conditions that simply aren’t achievable at atmospheric pressure. But no single vacuum technology fits every process. Steam jet ejectors, liquid ring pumps, and hybrid systems each have distinct operating profiles, and the right choice depends on your process load, required vacuum level, and available utilities.
Artisan’s vacuum systems engineering team works directly with customers to evaluate process requirements and identify the right system configuration, whether that’s a single-stage ejector for a straightforward application or a multi-stage hybrid system for a facility with limited steam availability. All systems are designed and manufactured in the USA at Artisan’s Stoughton, MA facility, drawing on decades of vacuum system engineering expertise.

Vacuum Heritage

Artisan’s vacuum systems capabilities are built on the engineering heritage of JET-VAC® Technologies, a vacuum system manufacturer established in 1952 and part of Artisan since 1986.

Single Stage Ejector Systems

Single stage steam jet ejectors, referred to as Z-Stage systems, are engineered to handle large process loads containing both condensable and non-condensable gases, as well as small amounts of solids or liquids. When configured to discharge to atmospheric pressure, they generate a vacuum level of 75 mm HgA (75 Torr) and up.

With no moving parts, single stage ejectors are straightforward to operate and maintain, making them a reliable, low-complexity choice for applications where a moderate vacuum level is sufficient.

Our engineering team can evaluate your process load and vacuum requirement to size the right configuration.

Multistage Ejector Systems

When deeper vacuum levels are required, multiple steam jet ejector stages are configured in series. Two-stage non-condensing systems (Y and Z-Stages) achieve vacuum levels of 10 mm HgA (10 Torr) and up. Multi-stage condensing systems, with 3 or more ejectors, up to 6 stages, can achieve vacuum levels as deep as 0.01 mm HgA (0.01 Torr).

Intercondensers positioned between the 4th/5th and 5th/6th stage jets reduce steam consumption by knocking out condensables from the process stream. An aftercondenser can be added to minimize condensables from the discharge vapor stream.

Hybrid Systems (Ejector + LRVP)

Hybrid vacuum systems combine steam jet ejectors, intercondensers, and a liquid ring vacuum pump to achieve the required vacuum level. The liquid ring pump serves as the final stage of a multi-stage system, replacing the last ejector stage and significantly reducing overall steam consumption.

The key advantage of hybrid systems is their compact, modular footprint and low-level on-grade installation, which eliminates the need for a barometric leg. This makes them well suited for facilities where vertical space or steam availability is limited. The trade-off is that the LRVP requires electricity, cooling water, and has mechanical seals and bearings that require periodic maintenance.

Our engineers can evaluate your steam availability, space constraints, and vacuum requirements to confirm if a hybrid system fits.

Liquid Ring Vacuum Pump Systems

Liquid Ring Vacuum Pump (LRVP) systems provide robust, continuous vacuum generation using a rotating liquid ring to compress process gases. They are particularly well suited for wet, condensable, or particulate-laden gas streams where other vacuum technologies may struggle, handling process conditions that can be difficult for dry-running equipment.

Artisan offers LRVP systems in both single stage and multi stage configurations, with the appropriate selection based on the vacuum level and process load required. LRVP systems require electricity and a small amount of sealing liquid, typically water, for continuous operation.
