MAXI
A portable and reliable ground thawing container solution with high capacity.
Focus on three key areas
1. User-friendly
Specifically designed with a focus on user-friendliness and packed with smart features.
All equipment, control panel, and service points are controlled from a single hatch. The insulation mats are placed in a basket on the roof, which easily folds backward for quick setup.
2. Reliable in operation
Like all our other machines, this one is specially designed with a focus on optimal reliability and long operational time.
To minimize downtime, we offer an emergency number that provides support 24/7, every day of the week.
3. Environmentally friendly
The Maxi 450 is fully electric, giving you the opportunity to use 100% clean, fossil-free electricity.
In addition to the environmental benefits, the electric operation allows for indoor use and is completely noise-free, contributing to a more comfortable workplace.
