Happy Anniversary ILTEC Technology - 

10 years of making industrial operations safer, greener and more cost-efficient!

In 2014 the first industrial scale ILTEC system has been implemented and since then the water free cooling technology has made many customers benefit from

  •  Safer operations – whilst keeping the same cooling effect

  • Energy savings – ILTEC enables more efficiency in heat recovery.
  • Higher availability of the equipment – ILTEC allows cooling of areas where water is not possible at all


The ILTEC Technology has been successfully implemented in a wide field of applications.

Let us explore together where ILTEC can support YOUR process!
