General overview

The Pfannenberg attachment and installation cooling units of the DTS and DTI series are stationary cooling units
for the dissipation of heat from switch cabinets. They are available in two versions:
 The DTI cooling units are partially recessed in the side or installed in the door.
 The DTS cooling units are mounted on the side or on the door.
The cooling units have different cooling outputs. For exact watt specifications, see
The cooling units have cut-out compatibility with air/air heat exchangers and air/water heat exchangers. Use of
aluminum filters, fleece filters and fluted filters is possible with an additional adapter.
The cooling units are available with different controllers. Cooling units are available with a standard controller (SC)
or a Multi-Controller (MC). These controllers are regulating units for the adjustment of refrigeration functions and
operating data. They also enable readouts of system messages and diagnostic data. The Multi-Controller (MC) is
also equipped with a Multimaster function and energy saving mode.
 For detailed specifications for the controller, see
All Pfannenberg cooling units are ROHS-compliant and free from:
