Viessmann’s switch to natural refrigerants enhances plug-in performance

Viessmann Refrigeration has invested heavily in new energy efficient systems to give foodservice operators an even greater choice of products.

Its ‘plug-in’ range of integral cabinets has moved from high GWP chemical refrigerants, such as R404a to a ‘0’ GWP hydrocarbon refrigerant, R290. This change in strategy aligned to the phase-out of certain chemical refrigerants as directed within the European ‘F-Gas’ regulations.

The switch from chemical refrigerants to natural refrigerants has provided Viessmann with an opportunity to enhance the performance of its plug-in range of integral cabinets through higher efficiencies in heat transfer that R290 offers in comparison to chemical refrigerants such as R404a.

The thermal efficiency properties of R290 versus R404a are such that the company has recorded energy efficiency gains against the same equipment model types of more than 25%.
