8 Maintenance Procedures for Industrial Chillers

2024-12-31

Eight maintenance procedures for industrial chillers are provided, including inspection, cleaning, alarm handling, regular inspections, etc., which are helpful for chiller maintenance.

Industrial Chiller Maintenance:

The various protection device settings of the industrial chiller unit have been set and should not be changed arbitrarily.
Regularly check whether the radiator system of the chiller unit is normal, whether the cooling tower fan and nozzles are operating normally, and whether the water replenishment of the built - in water tank of the chiller unit is normal. Regularly check whether there is any refrigerant leakage in the chiller unit: It can be judged by referring to the parameters displayed on the high - and low - pressure gauges on the front panel of the main unit.
When the unit issues a fault alarm, first press the alarm button, then check the cause of the fault. Remember not to force - start the unit before troubleshooting.
During use, if there is no emergency, do not cut off the power and turn off the unit arbitrarily. In winter, if the unit is out of use for a long time, first turn off the unit, and then turn off the main power supply to drain the water in the cooler completely.
When using an industrial chiller, keep the machine room clean and well - ventilated, and regularly clean the condenser to ensure the normal operation of the unit.
For air - cooled chiller units, after starting, check whether the fan rotation direction is correct. If the rotation direction is normal, it can be used normally. If it rotates in reverse, the power supply is reversed, and the phase sequence needs to be changed before starting again. In addition, ensure good heat dissipation effect. This requires keeping the surface of the cooling water radiator clean, ensuring air circulation around the machine, and a low temperature, and regularly cleaning the fins.
For water - cooled coolers, keep the cooling tower clean, ensure air circulation around the water tower and a low temperature, and avoid debris from entering the cooling tower to reduce heat dissipation.
The industrial chiller should be system - cleaned every six months and once a year. The main components to be cleaned include the cooling tower, hot water pipe, and condenser components to ensure better refrigeration. If the cooler has been in use for more than 6 months and frequently experiences dehumidifier or high - and low - pressure switch failures, or a decrease in cooling capacity, professional maintenance personnel should be invited for repair.
