Problem Identified
Henniges Automotive was faced with the following familiar water quality challenges in their closed loop chilled water system:
- Chronic corrosion
- Sludge buildup
- Frequent equipment clogging
- High dissolved oxygen levels
These issues were accelerating equipment degradation, clogging thermal control units, and forcing the maintenance team into a cycle of weekly system flushing and constant emergency intervention, even with chemical treatment and water softening.
Solution & Results
To stabilize system performance and reduce maintenance risk, Henniges installed an EasyWater Series C Closed Loop Treatment System on their most problematic loop.
Within three weeks of installation:
- Dissolved oxygen levels dropped to nearly zero
- System flushing was eliminated
- Thermal control unit clogging stopped entirely
- The loop remained stable without chemical intervention

Progress Since Treatment
Henniges Automotive was able to:
- Shift focus away from reactive maintenance and toward higher-value work
- Improve system reliability
- Extend equipment life
- Lower operational risk
All this was possible by replacing chemical-heavy treatment programs with proven, physics-based solutions.

EasyWater Series C Closed Loop Treatment
The 3 Major Problems in Closed Loops:
- Corrosion caused by dissolved oxygen
- Sediment and sub-micron metal particles in the water
- Insulating high iron content, limescale, and biofilm deposits
EasyWater Series C Closed Loop Treatment System provides a cost effective, low-maintenance, non-chemical treatment for controlling corrosion and scaling.
