As sustainability becomes a mandate, businesses face rising pressure to minimise environmental impact. Transitioning to natural refrigerants for temperature control systems is no longer just an option - it’s a necessity for reducing carbon footprints, cutting costs, and ensuring compliance with impending regulations.

In this expert report, produced in partnership with Peter Huber Kältemaschinenbau SE, we explore why the environmentally-friendly options should be front of mind for professionals when looking to invest in or upgrade equipment.
