Meet the “GadCooler”

Gadcooler is a new ship cooling tech that is designed to save energy. Targeting the ferry and cruise ship sectors to start, the company recently announced its ? rst installation success onboard Eckerö Line’s cruise ferry m/s Finlandia.

The Gadcooler Tech

In summertime and in tropical regions, cooling is typically a major onboard con- sumer of fuel. On big cruise ships oper- ating in tropical conditions cooling can consume as much as 10 MW of power.
