Why is the discharge pressure excessive in my CIAT DYNACIAT POWER LG Industrial Equipment?
- P
  Peter DuranAug 3, 2025
  If the discharge pressure of your CIAT Industrial Equipment is excessively high, several factors could be at play. It could be due to air in the hot water circuit, which requires draining the hot water circuit. Insufficient hot water flow rate can also cause this, so check the opening of the hot water circuit valves. If the cooling water flow rate is sufficient but the water temperature is too high, verify the correct operation of the regulator and setpoint adjustment. Issues with the tower or drycooler operation, a fouled or scaled condenser (requiring cleaning of the condenser tubes), or too much refrigerant (necessitating a check and adjustment of the load) can also lead to excessive discharge pressure.

How to troubleshoot low suction pressure in CIAT DYNACIAT POWER LG Industrial Equipment?
- V
  vfuentesAug 7, 2025
  If the suction pressure of your CIAT Industrial Equipment is too low, it could be due to several reasons. There might be air in the chilled water circuit, which requires purging. The chilled water flow might be insufficient, so check the opening of the chilled water circuit valves. If the chilled water flow rate is sufficient but the chilled water temperature is too low, check the pump's rotation, look for cavitation, and ensure the pump isn't too small. Also, a lack of refrigerant fluid could be the cause, requiring you to trace any leaks and top up the charge.

What to do if the fluid outlet temperature is too high in CIAT Industrial Equipment?
- A
  Adam MendezAug 11, 2025
  If the fluid outlet temperature of your CIAT Industrial Equipment is too high, and the low pressure is above normal, the controller setpoint might be incorrect, requiring correction. If the heat load is above the unit's capacity, adjust the water flow rate to the specified value using the control valve. If the water flow rate is too high, bypass the evaporator to obtain a greater difference in temperature with a lower flow rate to the evaporator. A faulty electronic control may also be responsible, so check the operation of the temperature and power controllers. If the low pressure is below normal, there may be a lack of refrigerant, requiring you to look for leaks and top up the load. Finally, check the expansion valve, as there might be an incorrect refrigerant supply to the evaporator.

What causes motor winding fault in CIAT DYNACIAT POWER LG Industrial Equipment?
- J
  Jerry WestAug 16, 2025
  If you are experiencing a motor winding fault in your CIAT Industrial Equipment, it could be due to several reasons. Start-ups might be too close together, disrupting the short-cycle protection; in this case, set the correct time between starts. The overload protection might be disrupted or defective, requiring adjustment or replacement. Additionally, the power supply voltage might be too low, necessitating a check of the electrical wiring; if needed, contact your electricity supplier.

What to check for a water flow fault in CIAT DYNACIAT POWER LG?
- V
  Victoria WilliamsAug 21, 2025
  If your CIAT Industrial Equipment is showing a water flow fault, it indicates that the water flow is either stopped or below the minimum rate. To resolve this, check that the valves on the water circuit are open and inspect the pump(s).

Why is the discharge temperature insufficient in my CIAT DYNACIAT POWER LG?
- A
  amandacombsAug 25, 2025
  If the discharge temperature of your CIAT Industrial Equipment is insufficient and close to the condensing temperature, it could be because the compressor draws in too much liquid. To resolve this, check and adjust the refrigerant load.

How to fix insufficient oil level in CIAT DYNACIAT POWER LG Industrial Equipment?
- W
  William HernandezAug 29, 2025
  If you notice insufficient oil in your CIAT Industrial Equipment, it might be because the oil was not topped up after servicing. To fix this, simply top up the oil.
