Case Study: Aarstiderne reduces energy use and carbon footprint with Danfoss CO₂ cooling solution

A real win-win situation Danish organic food company reduces climate footprint with CO₂ cooling solution

Aarstiderne, a Danish organic food company with a growing subscription-based delivery business, needed a more sustainable and scalable cooling solution for its Barritskov facilities. Working with Danfoss components through refrigeration installer JF Køleteknik A/S, the company set out to replace older standalone HFC systems, reduce energy use, and lower its carbon footprint while supporting future expansion.

Danfoss helped enable a transcritical CO₂ cooling system built around the AK-PC 782A controller and other Danfoss valves, sensors, modules, and power supplies. The new system delivered about 30% predicted energy savings, removed 40 kilos of HFC refrigerant with a GWP of 3,500, and replaced it with 200 kilos of CO₂ with a GWP of 1. It provides 147 kW of cooling capacity, expandable to 175 kW medium-temperature and 30 kW low-temperature capacity, giving Aarstiderne a flexible, lower-emission, lower-cost solution.
