Pfannenberg DTI 6401 230V MC Recessed Cooling Unit, 2 kW

DTI 6401 230V MC cooling unit: decoded part number

The DTI 6401 230V MC is a 2000 W Green Series cooling unit for partially recessed mounting in a cabinet door or side wall, with the Multi Controller. Because part of the housing lies inside the cut-out, the projection is reduced compared with the outer-mounted DTS version, which matters in narrow aisles and containers.

Decoded: DTI = partially recessed mounting, 6401 = 2 kW Green Series model, 230V = single-phase 230 V supply and MC = Multi Controller. The order number is 13899421055.

Technical specifications of the DTI 6401 230V MC

Values are from the product page for article 13899421055. Airflow figures differ in layout between the sheet and the page and are therefore not quoted.

How the DTI 6401 230V MC works

This is the same closed-loop refrigeration technology as the outer-mount DTS 6401, packaged for recessed installation. The compressor circuit cools and dehumidifies internal air, and a separate external air path carries the heat away. A condensate evaporator handles moisture, and a safety overflow is provided.

The Multi Controller adds data features compared with the standard controller; together with the service port it can be read by the εCOOL-Plant software to display operating data and fault history.

Because the unit is recessed, the enclosure must have a free internal space of about 120 mm in the mounting area; internal equipment must not obstruct the air outlet or inlet.

Fit in the system and related Pfannenberg parts

The DTI 6401 is the recessed alternative to the outer-mount DTS 6401 and has the same performance class. For smaller loads the 6201C and for bigger ones the 6X2E series come into play.

Selection and ordering checklist for the DTI 6401 230V MC

Before ordering the DTI 6401 230V MC, settle the following points so that the right variant is quoted:

• Heat load, target temperature and worst-case ambient (1500 W at A35/A50)
• Door or side-wall cut-out dimensions and 120 mm of free interior depth behind it
• Supply 230 V single-phase, 10 A protection
• Controller type and remote-data requirements
• Finish: powder-coated or stainless-steel V2A

Installation, commissioning and maintenance of the DTI 6401 230V MC

Cut out the door or wall according to the manufacturer drawing and seal the unit against the panel so that the stated enclosure-side protection is achieved. The unit is heavy, so use suitable lifting equipment and check that the door hinges can carry the load if the unit is mounted on a door.

After wiring and closing the cabinet, start the unit and check the temperature setpoint, fan rotation and condensate path. Review the controller for alarms after a few hours.

• Clean condenser and filter at regular intervals
• Verify door seals and cut-out gasket annually
• Review the parameter history through the service port
• Have refrigerant checks done by qualified personnel

Typical applications in Oman and the GCC

Recessed cooling units are common on machine builders’ cabinets, packaged skids and containerised power rooms where the outward projection of an outer-mounted unit would be a problem. A 2 kW class cools drive and PLC panels, battery cabinets and instrument racks in desert and coastal sites.

In practice the choice between a DTI and DTS comes down to the wall: recessing frees floor space outside but demands interior space, so confirm what is behind the cut-out before ordering.

Site conditions in Oman for the DTI 6401 230V MC

Panel cooling in Oman is sized for the worst case, not the average day. Summer shade temperatures in Muscat, Sohar and the interior regularly pass 45 °C, and a cabinet standing in direct sun gains further heat through its walls. When you size the DTI 6401 230V MC, add the internal losses of drives, power supplies and PLCs to the solar and wall gain, and compare the total with the useful cooling capacity at your real ambient and target cabinet temperature, rather than with a nominal figure stated at milder test conditions.

Coastal sites near Duqm, Salalah or Sur also bring humidity and salt-laden dust. Keep door seals intact, route the condensate drain away from live parts, and plan routine filter and coil cleaning so that the DTI 6401 230V MC keeps its rated performance through the long summer season.
