Why Atlas Copco Uses Stainless Steel Coolers
Atlas Copco stainless steel coolers are better suited for a wider range of cooling water conditions than traditional copper coolers.
Wider Water Tolerance
More adaptable to different cooling-water quality conditions.
Corrosion Resistance
Improved resistance in acidic and alkaline environments.
Long Service Life
Lower leakage risk and stable long-term heat exchange performance.
Cooling Water Condition Comparison
| Constituent | Chemical Formula | Units | Copper Cooler Recommended Range | Means of Treatment | Stainless Steel Cooler Range |
|---|---|---|---|---|---|
| Electrical Conductance [25°C] | - | μS/cm | under 800 | degree of total ionizable or dissolved solid in the water | < 4000 |
| Hardness | - | mg/L as CaCO3 | under 150 | softening; demineralization | < 500 |
| M-Alkalinity | - | mg/L as CaCO3 | under 100 | lime and lime-soda softening; acid treatment or etc | |
| Turbidity | - | degree | under 20 | coagulation, settling and filtration | |
| pH [25°C] | pH=log(1/H+) | - | 6.5 ~ 8.0 | controlled by alkalies or acids | 6.6 – 9.3 |
| LSI | LSI=pH-pHs | - | 0.0 ~ 1.0 | stability index | |
| Iron | Fe2+ (ferrous) Fe3+ (ferric) | mg/L as Fe | under 1.0 | aeration; lime softening or etc | |
| Chloride | Cl- | mg/L as Cl- | under 200 | demineralization, reverse osmosis, electrodialysis | < 400 |
| Sulfate | SO4²- | mg/L as SO4²- | under 200 | ||
| Silica | SiO2 | mg/L as SiO2 | under 50 | hot and warm process removal | |
| Ammonium | NH4+ | mg/L as NH4+ | under 1.0 | chlorination, deaeration or etc | < 500 |
Long Service Life
No electrochemical corrosion.
More resistant to acidic and alkaline corrosion than copper coolers.
| Potential Difference | Value |
|---|---|
| Cu-Al | 1.67 V |
| SS-Al | 0.89 V |
Condensate in coolers
Copper tube coolers with aluminum fins are easy to corrode.
Leakage occurs.
Corrosion leads to insufficient heat exchange and causes airend problems.
Manufacturing Method Comparison
| Copper Cooler - Hot Expansion | Stainless Steel Cooler - Argon Arc Welding |
|---|---|
 Plastic Deformation Causes stress corrosion |   Elastic Deformation Increases heat exchange area |
 Expansion Joint Poor reliability |  Fully Automatic Robotic Welding High reliability |
Expansion joints and stress corrosion can easily form leakage points. Leakage points cause insufficient heat exchange area. | High welding reliability. Because the heat transfer coefficient is lower than copper, the heat exchange area is increased to ensure heat transfer capacity. |
 Water flows through the tube side, air flows through the shell side. Straight tube design, easy to clean. |
High Quality Water Cooler
Coolers are arranged in parallel.
Both front and rear covers can be opened.
Water flows through the tube side, air flows through the shell side.
Straight tube design, easy to clean.
