Page 4: Technical Information
4. Technical information Air - water heat exchangers are intended as complementary accessories to large industrial equipment which include a motor-operated fan or blower together with a cooling heat exchanger. These may also include an electric heater. The fan or blower is intended to recirculate air and allow heat exchange. The heat exchanger is designed for chilled water or anti-freeze/corrosion inhibitor mixed water from a separate source.
Page 5: Functional Principle
Potassium manganate consumption < 1.46 gr/gal Suspended matter < 0.1753 gr/gal (part flow cleaning recommended) > 0.1753 < 0.8763 gr/gal (continuous cleaning) > 0.8763 gr/gal 5. Functional principle The air inside the control cabinet is moved over a laminar heat exchanger through which a coolant medium runs, making use of the counter-flow principle.

Page 11: Taking Into Operation
11. Taking into operation The cooling performance of the heat exchanger is dependent on the water flow rate available from the supply. The water flow is dependent on the water supply system to which the heat exchanger is connected and is affected by various factors, such as conduit pressure, conduit diameter, etc. 1.

5. Units with temperature controller The unit is equipped with a temperature controller which regulates the function of the unit. On normal working conditions the display shows the temperature inside the enclosure. The controller “set point” for the interior of the enclosure (parameter St / St1) is pre-set at 95°F and can be adjusted between +68°F and +122°F.

When connecting the new fan, take care that the correct polarity is maintained. 2.Thermostat replacement Before replacing the thermostat, isolate the equipment from the power supply (pull out mains plug or connecting cable). Detach the thermostat from its support by unclipping it from the DIN railing and loosening the 4 connecting cables.
