Intended use

The Pfannenberg add-on and built-in cooling units of the DTS and DTI series are stationary cooling units for heat dissipation
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 20.
The cooling units have cut-out compatibility with air/air-heat exchangers and air/water heat exchangers. The use of aluminum
filters, felt filters or bellows filters is possible with an additional adapter.
The cooling units are delivered with different controllers. Cooling units with a Standard-Controller (SC) or a Multi-Controller (MC)
are available. The controllers are control units for setting refrigeration functions and operating data. They also allow readouts of
system messages and diagnostic data.
The Multi-Controller (MC) is additionally equipped with a Multimaster function and an energy-saving mode.
• For detailed information about the controller, see section "Technical data", Page 20, "Electrical connection", Page 32and
"Operation", Page 42.
All Pfannenberg cooling units are RoHS compliant and free from:
• silicone compounds
• PCT, asbestos, formaldehyde, cadmium
• Substances that interfere with wetting
