Wet gas scrubbers · Gas analysers
Every industry emits. We make sure it’s clean when it leaves — and prove it.
Lechler designs bespoke wet scrubber installations that capture harmful gas emissions before they reach the atmosphere, paired with precision analysers that continuously measure and verify what’s released — proven across chemical, maritime, and heavy industry.
What we do
Complete installations for clean process emissions
We design, build and install wet gas scrubbers for industrial gas streams, together with the analysers that control them. Engineering, workshop and service all sit in one company.
Wet gas scrubbers
Vertical columns and horizontal counter-current scrubbers, single- or multi-stage, in PP, PE, PVDF, GRP or stainless steel. Learn more
Engineering & design
Process design, 3D models in Autodesk Inventor with stress analysis, and electrical design in Eplan. Learn more
Workshop & panel building
Welding, assembly and control cabinets built and tested in our own workshops, with a factory acceptance test if you want one. Learn more
Gas analysers & monitoring
Process analysers that control the installation and verify emissions, maintained and calibrated by our own service engineers. Learn moreIndustries
Where our scrubbers run
A selection of the twelve industries we work for. Every photo shows one of our own installations in that sector.
Featured solution
The vertical scrubber
A column in which the gas is washed by a counter-current spray system. The gas enters at the bottom through a half-pipe inlet for an even, laminar flow, and the washing liquid is sprayed through non-clogging full cone nozzles.
- Counter-current spray, single- or multi-stage
- Built in plastic (PP, PE, PVDF, GRP) or stainless steel
- Supplied with pumps, instrumentation, control cabinet and PLC
- Process analysers for control and verification
- Factory test in our workshop, commissioning and training on site
Our approach
From first analysis to clean emissions
One team takes your project from the first conversation about your process to service after start-up.
-
01
Analyse
Your process, the pollutants, the gas flow and its particle or chemical load.
-
02
Engineer
Process design, 3D model, stress analysis and the electrical design.
-
03
Build
Welding, assembly, panel building and PLC programming in our own workshops.
-
04
Install
Assembly on site, commissioning together with you and training for your operators.
-
05
Support
Maintenance, analyser calibration and remote monitoring if you want it.
