Pfannenberg PWI 6302C 230V Recessed Air/Water Heat Exchanger

PWI 6302C 230V air/water heat exchanger: decoded part number

The PWI 6302C 230V is a partially recessed air/water heat exchanger of the εCOOL range, rated at 3000 W with cooling water at 400 l/h. Part of the housing sits inside the door or wall cut-out, with an installation depth of 60 mm, so the unit projects less into the room than an outer-mounted exchanger.

Decoded: PWI = partially recessed air/water heat exchanger, 6302C = the C version of the 3000 W εCOOL model, with its own dimensions and weights on the sheet, 230V = single-phase 230 V supply. The order number is 12892601055.

Technical specifications of the PWI 6302C 230V

Values are from the product page for article 12892601055 and the series sheet. Rated at 10 °C inlet water and 35 °C air.

How the PWI 6302C 230V works

Cabinet air is circulated over a finned coil fed with cold water, and the heat leaves in the water circuit. An integrated thermostat controls the solenoid valve, so water flows only on demand, and a temperature monitor with alarm contact reports faults.

The manufacturer states that the unit is cut-out compatible with the εCOOL cooling units and air/air heat exchangers, and that the PWI mounts with a click-and-fit system, which shortens installation time. It is described as maintenance-free.

The 6302C is lighter at 18.8 kg and shorter at 938 mm than the PWS 6302 (28 kg, 1556 mm), at the same 3000 W rating, which is why it is useful for door mounting and for smaller cabinets.

Fit in the system and related Pfannenberg parts

The PWI 6302C sits in the same family as the PWS 6302C (outer mounting) and the PWI 6152 (1500 W). It belongs to the εCOOL PWx 6000 range.

Selection and ordering checklist for the PWI 6302C 230V

Before ordering the PWI 6302C 230V, settle the following points so that the right variant is quoted:

• Heat load against 3000 W at the available water temperature
• Water supply: 400 l/h up to +35 °C and 10 bar
• 230 V 1~ supply with T 2 A protection
• Cut-out of the door or wall and 60 mm installation depth
• Whether compatibility with existing εCOOL cut-outs is wanted

Installation, commissioning and maintenance of the PWI 6302C 230V

The click-and-fit system lets the unit be pressed into the cut-out and locked; do not omit the seal. Connect 13 mm hose nozzles to the water, add shut-off valves, vent the circuit and verify there are no leaks before starting.

Commission by running the system and checking the alarm contact, thermostat setpoint (factory +35 °C) and the condensate drain.

• Check hoses and clamps
• Clean coil and condensate path
• Check the water quality
• Test the alarm contact

Typical applications in Oman and the GCC

The recessed design is useful on control-room cabinets and machine doors where outside projection must be limited. It is a candidate for drive cabinets, PLC racks and instrument panels in power, desalination and gas-processing plants that provide cooling water.

The unit is water-cooled, so it works in rooms where the ambient is high, as long as the water loop is stable. Before ordering, compare the 6302C with the plain PWI 6302: both are rated 3000 W but the sheet gives different weights and airflow figures for the two, so the article number should be confirmed against the cut-out and the weight your door can carry. Seven Star LLC can check this against the sheet when you send the existing cabinet drawing.

Site conditions in Oman for the PWI 6302C 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 PWI 6302C 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 PWI 6302C 230V keeps its rated performance through the long summer season.
