Explore the different components of Envitech Systems:

Direct Contact Condenser

Transfers heat from gas to liquid removing water vapor from the gas stream in the process.

Envitech’s Direct Contact Condensers (DCCs) deliver efficient heat and mass transfer by bringing gas and liquid streams into direct contact. This simple yet highly effective design maximizes thermal efficiency, enabling efficient temperature control and energy recovery.

Envitech engineers DCCs in multiple configurations — including spray towers, packed bed towers, and tray towers — to meet the needs of a wide range of industrial applications. Whether used to cool process gases, recover heat, or generate condensate, each system is tailored for high reliability and performance.

DCCs serve multiple process objectives: recovering heat for use in preheating or material melting, cooling gases to form condensate, condensing acids and volatile compounds, growing fine particulate for improved collection, reclaiming water in arid climates, and suppressing visible stack plumes.

Envitech’s DCCs combine robust construction with engineered efficiency — helping plants reduce emissions, lower energy costs, and maximize uptime.

NOx Scrubber

Envitech offers several technologies for the absorption or destruction of NOx from challenging process applications where conventional technology fails.

Envitech’s NOx scrubbers deliver proven results for controlling nitrogen oxides in the most demanding industrial environments. Using advanced absorption technology, these systems convert and capture NO and NO₂ with exceptional efficiency—all while minimizing operating cost.

Tailored to each process, Envitech applies optimized chemistries and absorber designs to ensure complete NOx conversion and absorption. Inlet gases are treated with injected or in-situ oxidants that transform nitric oxide into nitrogen dioxide, which is then absorbed in a high-performance packed bed. Counter-current gas and liquid flow, combined with engineered distribution systems, ensures rapid reactions, compact equipment sizing, and reliable performance.

Available in corrosion-resistant FRP or robust metallic construction, Envitech NOx scrubbers are designed for long service life and dependable operation. Proven in applications such as waste incineration, chemical reactors, and metal finishing, these systems meet stringent emission standards while providing lower maintenance and energy costs than conventional solutions.

Vent Scrubber

Envitech cost-effective wet scrubbers remove contaminants from laboratory fume hoods and batch production facilities.

Envitech’s custom-engineered scrubbers provide solutions for controlling low-flow gas emissions where performance and reliability are critical. Designed for complex chemical and industrial processes, these systems effectively capture toxic vapors, recover valuable minerals and compounds, and prevent emissions from even the most challenging sources.

With decades of process expertise and a full range of proven technologies, Envitech delivers the right solution for every low-flow application. Absorbers capture soluble gases, Venturi scrubbers handle sticky or particulate-laden streams, and wet electrostatic precipitators remove fine aerosols and condensables. Advanced controls—including variable frequency drives, automated valves, and intelligent algorithms—ensure stable performance and optimal efficiency.

From pharmaceutical batch reactors and laboratory fume hoods to refinery vents, pilot plants, and mineral roasters, Envitech’s low-flow systems have a proven track record of reliability and compliance. Each system is shipped fully assembled, factory-tested, and ready for rapid installation—reducing project time, cost, and risk.
