Pfannenberg DTS 6401 230V Green Series Cooling Unit, 2 kW

DTS 6401 230V SC cooling unit: decoded part number

The DTS 6401 230V SC is a 2000 W side-mount cooling unit from the Pfannenberg Green Series. It cools the air inside a sealed electrical enclosure with a refrigeration circuit and discharges heat to the surrounding air, so it keeps electronics at a set temperature even when the ambient air is warmer than the allowed inside temperature.

The name decodes as: DTS = side mount on the outside of the door or wall, 6401 = Green Series 2 kW model, 230V = 230 V single-phase supply and SC = Standard Controller. The article number is 13889411055 and the colour is RAL 7035.

Technical specifications of the DTS 6401 230V SC

Values are from the product page for article 13889411055. The sheet and page describe the internal and external airflow in a different order, so airflow figures are not quoted here; check the sheet for the circuit data.

How the DTS 6401 230V SC works

The unit has a closed refrigerant circuit with a compressor, so cooling does not depend on the outside air temperature being lower than the inside. Warm cabinet air is drawn through the evaporator and returned cooled; the condenser on the other side rejects the heat outside through a separate air path.

The Green Series aims at the lowest energy use for a given cooling capacity and a reduced refrigerant charge. The manufacturer also points to long air paths between intake and exhaust in the enclosure, so that hot spots are not left uncooled, and a service port to read the parameter history with the εCOOL-Plant software.

The SC controller provides a straightforward thermostat function with setpoint, while the MC controller extends this with data and energy-saving functions. The filter is optional and can be added without tools.

Fit in the system and related Pfannenberg parts

This is one of the larger side-mount units in the Green Series, above the 1 kW 6201C and below the X-Series, which reaches higher capacities.

• MC version, same unit: article 13889421055
• Three-phase 400 / 460 V version, SC: article 13889412055
• Partially recessed DTI 6401: article 13899411055 (SC, 230 V)
• Stainless-steel (V2A) version: article 13889411015 for the SC, 230 V variant

Selection and ordering checklist for the DTS 6401 230V SC

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

• Heat load and target cabinet temperature, and the worst-case ambient (capacity is 1500 W at A35/A50)
• Supply: 230 V single-phase with 10 A protection, or a 400 / 460 V variant
• Space for 485 mm x 1547 mm of door or wall surface and 278 mm of projection
• SC or MC controller, stainless steel or painted housing
• Optional filter and external condensate options

Installation, commissioning and maintenance of the DTS 6401 230V SC

The unit is mounted vertically on the door or wall. Plan the bolting and cut-outs before delivery and make sure the wall can carry the weight listed on the sheet. Keep the enclosure sealed; the unit protects at IP55 towards the cabinet only when door seals and cable entries are intact.

At commissioning set the temperature target; the sheet gives a range of +25 °C to +50 °C on the SC version. Avoid setting the target too low, since a very low set-point increases condensation and compressor cycling.

• Clean the condenser and any filter regularly; sandy sites require frequent attention
• Inspect the condensate evaporator and drain path
• Read operating hours and error history through the service port
• Check the refrigerant circuit only through qualified refrigeration personnel

Typical applications in Oman and the GCC

With 2000 W of capacity this unit is a common choice for motor-control centres, drive panels, PLC cabinets and instrument racks at power stations, desalination plants and gas processing sites where heat loads reach a kilowatt or more. In Oman and GCC summers the capacity at +50 °C ambient (1500 W) is the working figure for outdoor kiosks; the +35 °C figure is only valid in conditioned rooms.

Because the unit keeps outside air out of the cabinet, it also protects electronics from dust, humidity and salt that would enter through filterfans on coastal installations.
