Pfannenberg DTS 6X1E 230V Side-Mount Cooling Unit

DTS 6X1E 230V side-mount cooling unit with variable capacity

The DTS 6X1E 230V is the side-mounted cooling unit of the Pfannenberg X-Series for 230 V single-phase supply. It adjusts its output between 1,000 and 2,800 W with a Premium Controller. Seven Star LLC supplies the DTS 6X1E 230V in Oman and the GCC as an independent supplier in Muscat.

DTS indicates the side-mount form, 6X1E the model with premium controller and 230V the supply. The article number is 13887331555. The electrical and cooling data match the partially recessed DTI 6X1E 230V; the two parts differ in how they attach to the cabinet and in their height of 1,547 mm against 1,538 mm.

DTS 6X1E 230V technical specifications

Side mounting of the DTS 6X1E 230V

A side-mounted unit is fixed to the outside of the cabinet wall, with air ducts passing through two openings. Nothing protrudes into the cabinet, so the full interior volume and the mounting plate space remain available. The cost is the projection of 278 mm into the aisle, which matters in narrow switchgear rooms and on skids.

When internal space is the limit, side mounting is preferred; when the aisle is the limit, the partially recessed DTI form is better, though it takes 60 mm of installation depth. Check both before deciding on the cabinet layout.

Premium controller functions of the DTS 6X1E 230V

The controller is the Premium Controller of the series, and the thermostat point is adjustable from +25 to +50 °C. The wide capacity band in the data table points to an efficiency advantage at partial load. The product sheet for the series lists further functions and interface options, so check it when monitoring through a PLC is required.

Fit in the system and related parts

Use the DTS 6X1E 230V on cabinets of 2 metres height and above, or on wide cabinets with a high load. For a smaller cabinet look at the DTFS 6021 230V and its 6031 sibling; for larger heat loads, the DTS 6X2E. A 400 V version of the DTS 6X1E exists for three-phase supply.

DTS 6X1E 230V selection and ordering checklist

• Heat load, with a margin against 2,100 W at A35/A50
• Set temperature and the alarm contact requirements
• Maximum ambient up to +55 °C
• Cabinet wall strength for a tall unit
• 230 V supply with a C 10 A fuse
• Space in the aisle for 278 mm projection
• Cut-out template and sealing requirements

Installing and maintaining the DTS 6X1E 230V

Mark and cut the openings with the manufacturer template, deburr and seal the edges, and fix the unit with the gasket. Connect the plug-in terminal. After switch-on, check the direction of both air flows and leave the cabinet door closed during commissioning.

Inspect the condenser and the external filter regularly, since dust in a desert environment can block a condenser within weeks. Clean with compressed air or a soft brush and avoid bending the fins.

Typical DTS 6X1E 230V applications in Oman and the GCC

Oil and gas, power, desalination and petrochemical sites in Oman and the GCC put electrical enclosures in hot rooms, outdoor shelters and dusty yards. This unit protects large drive cabinets, switchgear compartments, control rooms in containers, and outdoor cabinets exposed to the sun, where the ambient temperature regularly exceeds the allowed temperature inside the enclosure.

DTS 6X1E range

Think about what happens if the unit stops. The cabinet will start to heat up at a rate that depends on the load, and in a closed cabinet in a hot climate the temperature can reach protection limits within an hour or two. Wire the alarm contact to the SCADA or to a local beacon so that operators see a failure early, and keep a record of the filter cleaning dates. For critical cabinets some plants install two smaller units rather than one large one, so that the loss of one still leaves partial cooling. Discuss the design with us if redundancy is required for the project.

Site conditions in Oman for the DTS 6X1E 230V

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 DTS 6X1E 230V, 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 DTS 6X1E 230V keeps its rated performance through the long summer season.
