EST™ scrubbers and process equipment have been providing safe gas abatement for municipal and industrial customers since 1983. From a single component to fully engineered packages, the reliable design and construction provides peace of mind even in the most corrosive environments.



Reliability / Equipment Longevity

Regulatory Compliance

Cost Savings / Reduced Operational Cost

The EST line of industrial and municipal scrubbers includes standard and custom designed wet and dry scrubbers for emergency gas abatement, odor scrubbers, particulate scrubbers, and a complete line of systems for industrial installations. We also offer a wide range of materials of construction to handle the most corrosive environments.

EST desuperheater designs use uniquely effective methods to reduce the temperature of superheated steam. EST desuperheaters are available in a wide range of sizes and materials to suit a variety of power industry applications.

A complete line of EST eductors and syphons in a wide range of sizes and materials 

Standard and custom designed EST in-line blowers, and liquid jet exhausters. These ejector venturi devices entrain and pump air, gases, or process vapors.



EST in-line gas jet blowers entrain and pump air, gases, or process vapors, typically using less motive fluid than compressors and pumping large amounts of suction fluid at slight vacuums.

Heating Systems
EST steam heaters can be used in any process that requires heating with steam. Offered in a variety of proven steam heater designs incorporating both direct contact units as well as shell and tube designs.

Conveying Solids
EST conveying solids eductors economically transport free flowing solids, powders and slurries with an available liquid or gas pressure source. Solids can be transported for distances up to 400 feet pneumatically and further using water or other liquid as a transport medium.

Vacuum Systems
EST steam jet vacuum ejectors are devices that use steam as a motive source to pull gases under vacuum. Available as single stage, multi-stage, condensing, non-condensing, or hybrid systems with liquid ring pumps. Since steam jet vacuum ejectors have no moving parts, they eliminate the maintenance and mechanical failure concerns associated with other vacuum sources, greatly reducing costly down time.
