Mazda Limited designs and manufactures vacuum process equipment and industrial vacuum systems for power generation, petroleum refining, chemical processing, pharmaceuticals, fertilizers, edible oil refining, and other process industries. Our vacuum solutions support processes including distillation, evaporation, crystallization, drying, solvent recovery, degassing, and steam condensation.
Since 1977, Mazda’s Ahmedabad facility has engineered process equipment to ASME, HEI, and TEMA standards, holding ISO 9001, ISO 14001, and ISO 45001 certification along with PED, IBR, ASME, and U-Stamp compliance. Rather than relying on fixed, off-the-shelf configurations, every system is engineered around the specific installation’s required vacuum level, process capacity, operating temperature, and available utilities – with systems installed across multiple continents, including reference projects for Reliance Industries (Jamnagar Refinery), Jindal Steel & Power, and Triveni Turbines.
Our portfolio includes steam jet ejectors, hybrid vacuum systems, liquid ring vacuum pumps, thermo compressors, boosters, condensers, and supporting equipment – supplied individually or as complete integrated systems.
Vacuum process equipment creates and maintains pressure below atmospheric level within an industrial process or system. Reducing pressure lowers the boiling point of process liquids, which is why vacuum technology is central to distillation, evaporation, crystallization, drying, solvent recovery, degassing, and condenser air removal – supporting temperature control, product quality, and reduced oxidation.
The right technology depends on required vacuum depth, process capacity, operating temperature, process media, condensable and non-condensable load, and available utilities. Mazda evaluates these conditions before matching an installation to a steam jet ejector, liquid ring pump, hybrid combination, or specialized vacuum technology.
Steam-operated equipment that uses motive steam to generate vacuum, suited to applications needing reliable vacuum with low mechanical maintenance.
Steam Jet Air Ejector (SJAE) System – removes air and non-condensable gases from process and condenser systems using multi-stage steam jets.
Thermo Compressor – uses high-pressure motive steam to recompress lower-pressure steam, improving steam utilization in evaporators.
Steam Jet Liquid Heaters and Mixers – uses direct steam injection for heating and mixing liquids in industrial processes.
Combine two vacuum-generation technologies to reach deeper vacuum, greater load stability, or lower energy cost than either alone.
Combination System – Steam Jet Ejector + Liquid Ring Vacuum Pump – pairs ejector suction capacity with liquid ring pump stability for applications with variable load.
Combination System – Steam Jet Ejector + Liquid Jet Ejector – combines steam and liquid jet ejector stages for multi-stage vacuum requirements, installable at ground level.
Rotajector Ejector – a specialized hybrid ejector with a rotating assembly, designed for applications needing reduced steam consumption.
Provides continuous vacuum generation without dependence on a steam supply.
Single/Double Stage Liquid Ring Vacuum Pumps – mechanical vacuum pumps for continuous, moderate-vacuum duty, configurable as single- or double-stage.
Auxiliary equipment integrated into a vacuum system to improve steam utilization, condensation, and overall performance.
Multi Nozzle Booster – a multi-nozzle ejector design that can reduce steam consumption by 15-20% compared to single-nozzle boosters.
Barometric Condenser / Mixing Condenser – a direct-contact condenser that condenses process vapors via cooling water, removing the need for condensate pumps.
Chiller Vactor – provides evaporative process cooling without conventional refrigerants.
Water Heater with Holes (Orifice) – a direct steam-injection heater for rapid, uniform heating of water and other liquids.
Selecting a vacuum system requires evaluating the full process and operating environment, not just the target vacuum level. Key parameters: required vacuum pressure, process capacity, operating temperature, process gas and vapor characteristics, condensable and non-condensable load, available steam and utilities, energy requirements, installation conditions, and maintenance requirements.
| Application Requirement | Potential Technology |
|---|---|
| Steam is readily available and low mechanical maintenance is important | Steam Jet Ejector |
| Continuous moderate-vacuum duty with a suitable sealing liquid | Liquid Ring Vacuum Pump |
| Variable load or combined vacuum requirements | Hybrid / Combination Vacuum System |
| Improving steam utilization in an existing ejector system | Multi-Nozzle Booster |
| Recompressing low-pressure steam for reuse | Thermo Compressor |
Final equipment selection should be based on detailed process conditions and system calculations – Mazda’s engineering team evaluates each site’s parameters before recommending a configuration, rather than offering a fixed, off-the-shelf system.

Mazda’s vacuum process equipment is deployed across:
Where required, vacuum systems are engineered around the process conditions, capacity, operating environment, and utility availability of each installation.
Mazda Limited has manufactured vacuum and heat transfer equipment since 1977, holding ISO 9001, ISO 14001, and ISO 45001 certification, PED compliance, and IBR, ASME, and U-Stamp accreditation. Our approach combines process engineering, equipment design, and manufacturing expertise — from application-specific system design and technology selection to equipment integration, quality-controlled manufacturing, and after-sales technical support for both domestic and export customers.
Vacuum process equipment consists of industrial systems - such as steam jet ejectors, liquid ring vacuum pumps, and hybrid vacuum systems - that create and maintain pressure below atmospheric level for processes like distillation, evaporation, drying, crystallization, and solvent recovery.
Petroleum refining, chemicals and pesticides, pharmaceuticals, fertilizers, edible oil refining, and power generation are among the primary industries using Mazda's vacuum process equipment.
A steam jet ejector uses motive steam and has no conventional rotating components, making it low-maintenance but dependent on a continuous steam supply. A liquid ring vacuum pump uses mechanical rotation and a sealing liquid to generate vacuum, requiring routine maintenance but no steam. Combination systems use both to balance vacuum depth, load stability, and running cost.
Selection depends on required vacuum level, process capacity, operating temperature, process media, gas and vapor load, available utilities, energy requirements, installation conditions, and maintenance requirements. Mazda's engineering team evaluates these parameters before recommending a configuration.
Yes. Mazda's vacuum equipment is engineered to fit specific site conditions, including retrofits, elevation constraints, and corrosive process environments.
Both. Mazda manufactures a full range of vacuum process equipment - steam jet ejectors, hybrid vacuum systems, liquid ring vacuum pumps, thermo compressors, boosters, and condensers - supplied individually or integrated into complete systems depending on the application.
