Pfannenberg PWS 7062 Air/Water Heat Exchanger, 600 W

Slim air/water heat exchangers for plants with chilled water

The Pfannenberg PWS 7062 is a slim air/water heat exchanger with 600 W cooling capacity, and the PWS 7102 delivers 950 W at the same test condition. Where a plant already has a chilled or cooling water circuit, an air/water heat exchanger removes cabinet heat into the water without a compressor, which makes it simple, quiet and efficient. The device is maintenance-free, can be installed completely inside, outside or partly through the wall, and has a mounting-friendly seal that avoids elaborate rework of the cut-out.

An integrated thermostat and solenoid valve control the water flow, and integrated temperature monitoring with an alarm contact reports a fault. Because the cooling medium is water at +1 to +35 °C, the cabinet can be held below the ambient temperature as long as the water is cooler than the required inside temperature.

Technical specifications

Water-side design notes

The listed performance is at 10 °C water and 35 °C ambient with a flow of 200 l/h; changing the water temperature or flow changes the capacity, and the sheet gives the curve against water flow. The manufacturer lists a 10 bar maximum, a +1 to +35 °C inlet range and copper pipe with aluminium fins, so water quality and corrosion inhibitors should be agreed for the circuit, and stainless piping is available on request. Condensate forms when the water is colder than the dew point of the cabinet air, so the unit has a condensate drain; an external condensate evaporation system (18314000001) and a condensate bottle (18314000100) are listed as accessories.

Selection and what to confirm before ordering

Compare the heat load of the cabinet with 600 W for the PWS 7062 or 950 W for the PWS 7102 at the planned water temperature and flow, and check the water supply is available at the cabinet location. Confirm voltage, hose or other water connection, the IP class and the finish. For sites without a water circuit use a refrigerant-based unit such as the DTT 6301 or the Rittal Blue e+ wall-mounted cooling units; see the Cooling category.
