Why is the discharge pressure excessive in my CIAT Chiller?
- K
  Kathleen MillerAug 12, 2025
  Excessive discharge pressure in your CIAT Chiller can be caused by several factors. These include air in the hot water circuit, insufficient hot water flow rate, cooling water flow rate being sufficient but the water temperature being too high, the tower or drycooler operating incorrectly, a fouled or scaled condenser, or too much refrigerant. To resolve this, you can try the following: * Drain the hot water circuit. * Check the opening of the hot water circuit valves. * Check the correct operation of the regulator and setpoint adjustment. * Check the operation of the tower or drycooler. * Clean the condenser tubes. * Check and adjust the refrigerant load.

  Rachel CohenAug 16, 2025
  If the suction pressure is too low in your CIAT Chiller, it could be due to several reasons. It might be caused by air in the chilled water circuit, insufficient chilled water flow, chilled water flow rate being sufficient but the chilled water temperature being too low, or a lack of refrigerant fluid. Here's what you can do: * Purge the chilled water circuit. * Check the opening of the chilled water circuit valves. * Check the direction of rotation of the pump, ensure there is no cavitation, and verify the pump size. * Trace the leak(s) and top up the charge.

What to do if the fluid outlet temperature is too high in my CIAT Chiller?

  If the fluid outlet temperature is too high in your CIAT Chiller, it could be due to several reasons. If the low pressure is above-normal, the controller setpoint might be incorrect. If the heat load is above the unit's capacity. If the water flow rate is too high. An electronic control could be faulty. If the low pressure is below-normal, there could be a lack of refrigerant or incorrect refrigerant supply to the evaporator. Here's what you can do: * Correct the setpoint value. * Recalculate the heat load and check that the unit is not too powerful for this load. * Adjust the water flow rate to the specified value using the control valve. * Check the operation of the temperature and power controllers. * Look for leaks and top up the load. * Check the expansion valve.

What causes a water flow fault in a CIAT Chiller and how to fix it?
- A
  Alexis LesterAug 23, 2025
  A water flow fault in your CIAT Chiller typically occurs when 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 there insufficient oil in my CIAT DYNACIATpower LG Chiller?
- R
  Rebecca MorenoAug 27, 2025
  Insufficient oil in your CIAT Chiller may occur if the oil was not topped up after servicing. To fix this, top up the oil.

How to resolve a motor winding fault in CIAT DYNACIATpower LG?
- S
  Sean RayAug 31, 2025
  A motor winding fault in your CIAT Chiller can be caused by several issues. Start-ups may be too close together, disrupting the short-cycle protection. The overload protection may be disrupted or defective. The power supply voltage may be too low. Here’s how to address these: * Set the correct time between two starts. * Adjust or replace the overload protection. * Check the electrical wiring.

What causes insufficient discharge temperature in CIAT DYNACIATpower LG?
- S
  Shane TaylorSep 4, 2025
  If the discharge temperature is insufficient and close to the condensing temperature in your CIAT Chiller, it is possible that the compressor draws in too much liquid. Check and adjust the refrigerant load to resolve this.
