from switch cabinets. They are available in two versions:
The DTI cooling units are installed partly sunken into the side or door.
The DTS cooling units are mounted on the side or door.
The cooling units have different cooling capacities. For exact performance specifications, see section "Refrigeration circuit",
Page
