Pfannenberg PWS 6102 230V Air/Water Heat Exchanger 1 kW

PWS 6102 230V side-mount air/water heat exchanger, 1,000 W

The PWS 6102 230V is the smallest side-mount air/water heat exchanger of the Pfannenberg Ecool PWx 6000 series. It gives 1,000 W of cooling at a water flow of 200 l/h and weighs 11 kg. Seven Star LLC supplies the PWS 6102 230V in Oman and the GCC as an independent supplier in Muscat.

PWS stands for side mount, 6102 for the 1 kW class and 230V for the supply; the article number is 12881401055. The PWI 6102 is the partially recessed version in the same series. With a height of only 623 mm and a depth of 142 mm it fits small and medium cabinets.

PWS 6102 230V technical specifications

Capacity per watt of the PWS 6102 230V

The unit removes 1,000 W of heat while drawing only 68 W at 50 Hz, about 15 watts of heat removal for every watt of electrical power. A compressor cooling unit of similar capacity draws several hundred watts. The advantage comes from using the water loop: the plant chiller does the heavy lifting and the exchanger only needs a small fan.

If water is available at a temperature well below the cabinet set point, the exchanger is by far the most energy-efficient way to cool a sealed enclosure. If the loop temperature approaches the cabinet limit, capacity decreases and another solution is needed.

Side mounting on the PWS 6102 230V

The unit is fixed to the outside of the cabinet wall, so nothing protrudes inside, and its small weight of 11 kg allows mounting on side panels and doors of standard cabinets. The projection of 142 mm is modest, which suits plant rooms with narrow aisles.

Fit in the system and related parts

When the heat load grows, step up to the PWS 6152 for 1,500 W, the PWS 6302 for larger loads or the PWS 6502 for 5,000 W. A PWI 6102 gives the same capacity with a partial recess. Use hose connectors and shut-off valves on both water lines so the unit can be removed without draining the loop.

PWS 6102 230V selection and ordering checklist

• Total heat load below 1,000 W at the actual water temperature
• Water inlet temperature and flow of 200 l/h
• Pressure up to 10 bar
• Space for 623 x 380 mm on the cabinet side
• 230 V supply with 2 A gG
• Hose connection method
• Condensate drain location

Installing and maintaining the PWS 6102 230V

Fit with the gasket and the openings on the cabinet side, connect hoses to the nozzles with clamps and open the valves slowly to purge air. Check all joints for leaks before closing the cabinet.

Schedule an annual inspection of the enclosure-side coil and a flush of the water side if the circuit is open to the atmosphere. Replace hoses on a schedule that matches site practice.

Typical PWS 6102 230V applications in Oman and the GCC

Desalination, power, oil and gas and petrochemical plants in Oman and the GCC usually have a chilled water or cooling water loop available, and the electrical rooms are dusty, hot and sometimes corrosive. A 1 kW exchanger suits compact PLC and I/O cabinets, small drive panels, instrumentation racks and local control stations where a chilled water line passes nearby.

PWx 6000 range

Sizing deserves a short worked example. A small PLC cabinet holds a power supply losing 20 W, a drive losing 120 W and miscellaneous I/O adding 60 W, so the internal load is 200 W. In a hot room at 40 °C with the cabinet allowed to reach 35 °C, a filterfan cannot work, but cooling water at 20 °C can absorb the heat easily. A 1,000 W exchanger gives five times the needed capacity, so the water flow can be reduced and the fan run less, which saves energy. Always calculate with the real loss figures from the data sheets of the installed devices rather than their nameplate power.

Site conditions in Oman for the PWS 6102 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 PWS 6102 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 PWS 6102 230V keeps its rated performance through the long summer season.
