Gas drying by sorption or cooling
Gas drying through the use of sorption technology or systems using gas cooling is often a necessary prerequisite for subsequent technical processes. The reliable removal of even the smallest traces of moisture in gases is essential in many technical systems.

Gas drying by way of gas cooling
Gas cooling is an effective solution in order to dry biogas in the engine prior to combustion. In this process, water condenses out as a result of the gas being cooled, which improves the combustion process in the engine.
The NECA|tec® D type gascooling system enhances the combustion process in engines, extends the service life of engine oil and helps to prevent corrosion damage over the entire gas section.
- Robust design for enduring use
- Powerful cooling performance
- Different sizes, well adapted for any plant
- Easy to operate, automatic operation
- Stainless steel versions in the gas section
- Safe operating system
