Concrete: cool during use

Perfectly tempered fresh concrete guarantees the best building quality without cracks:  it must be cool but not too cold. This aspect is crucial for bulky building components. 


Cool intelligently - save costs

In co-operation with our partners we have developed a highly efficient refrigeration concept for reservoir dams.

  • We pre-cool the coarse aggregates using ice water 
  • Thereby reducing the electrical power consumption by about 50%
  • Proven in some of the largest hydropower dam projects in Asia such as the SE SAN 3 dam in Vietnam and the YEYWA dam in Myanmar.


Trust in Hansa cooling solutions. Combining first class components, economy, safety and service.
