The deal will see the Scottish company supply temperature control systems and temporary power units to the theatrical group's big top touring productions across the US, Canada, South America, Europe and Asia Pacific.
Montreal based Cirque du Soleil said each event will have an independent power supply which will not rely on the local electricity grid.
Along with that it highlighted a need for a constant temperature to be maintained at each performance to ensure the safety of performers even though tours will take place in warm and cool climates.
Aggreko's heating and cooling system will be installed to make sure that a target temperature is maintained throughout each show regardless of what the weather conditions are outside.
Louis Malafarina, Cirque du Soleil corporate alliances director, said: "This is a fantastic alliance for us. Aggreko will provide a complete solution for uninterruptable power along with an innovative and energy efficient temperature control solution that meets the unique needs of our Big Top touring shows.
"Aggreko will provide an integral part of our infrastructure, ensuring that our shows are performed to audiences all over the world."
Aggreko, which manufactures its systems in Dumbarton and employs around 5700 people around the world, has worked on major events ranging from the Olympics and football World Cup to music festivals such as Glastonbury.
Rupert Soames, Aggreko chief executive, said: "Our extensive experience in supporting major international events along with our global footprint, make Aggreko an excellent match for Cirque du Soleil's power and temperature control requirements.
"I look forward to a long and successful partnership between our two organisations."
Cirque du Soleil's contemporary circus themed shows, which do not include performing animals, are estimated to have been seen by around 90 million people across the world.
