Product Types / Refrigerant / Capacity

A new energy-efficient low-temperature storage facility deep-freezes and stores tuna with a modern NH3/CO2 cascade refrigeration system. Every day, around 2,250 metric tons/2,480 short tons of tuna fish or tuna loins can be stored in the LT storage rooms. Güntner equipped the logistics rooms with CO2 evaporators – the cubic CPGHN and the dual discharge CPDHN – that are operated via pumps, and the excess heat from the NH3 refrigeration cycle is dissipated via Güntner ECOSS evaporative condensers.
