    Why is my Pfannenberg Industrial Equipment unit not cooling sufficiently?

      Your Pfannenberg Industrial Equipment might not be cooling well due to several reasons: the fan may not be turning correctly (check the voltage or replace the fan), the cooling water might be too hot or the volume might be too low (check the cooling water supply). Also, the louvres on the heat exchanger might be dirty (clean with a brush or compressed air), the cooling water could be dirty (use only clean cooling water), or there might be additives in the cooling water, such as glycol, which can reduce cooling performance.

      If your Pfannenberg Industrial Equipment unit is constantly cooling, it could be because the solenoid valve coil is dirty and remains open (clean the valve). Another possibility is that the supply and return lines are confused (check the connections and direction of flow).

      If your Pfannenberg Industrial Equipment unit with a solenoid valve isn't cooling properly, first check the thermostat setting. If that's not the issue, the solenoid valve coil might be defective (replace the coil) or clogged (clean the valve).

      If your Pfannenberg Industrial Equipment unit with a water-capacity controller is not cooling well, check the thermostat setting first. If the setting is correct, the thermostat head might be defective (replace it) or the control valve could be clogged (clean the control valve).
