Two ammonia groups and two CO2 groups were installed in the new logistics centre of Wörndle Interservice in Castenedolo (Bresica). Equipped with a remote maintenance system and heat recovery for defrosting evaporators and heating premises, the system cools various foodstuffs in the 0°C - and deep-freeze range. For maximum sustainability, the refrigeration system was developed with energy efficiency and the use of natural gases in mind.
