Why KKT Chiller doesn't have enough refrigeration power?
- R
  Richard StoneAug 13, 2025
  Insufficient refrigeration power in your KKT Chiller can stem from several causes: air in the water circuit, a water agitation quantity that has fallen below the minimum, inadequate fresh air supply to the condenser, or insufficient refrigerant in the circuit. To resolve this, vent the system, ensure the water pipe cross-section is correctly designed (potentially opening the check valve fully or increasing the pipe cross-section), ensure sufficient fresh air supply and removal (eliminating any short-circuit between fresh and exhaust air), and locate and seal any leaks before refilling the refrigerant circuit.

What to do if KKT KSC refrigerating machine starts and stops short-termed?
- S
  santoskristinAug 17, 2025
  If your KKT Chiller's refrigerating machine starts and stops frequently, it may be due to insufficient fresh air supply for the condenser, causing the high-pressure pressostat to protect against overload. Another cause could be low pressure in the refrigerant circuit due to refrigerant leaks, which causes the pressure switch to shut down the compressor. Ensure adequate fresh air supply and eliminate any short-circuits between fresh air and exhaust air. Also, find and seal any refrigerant leaks before refilling the circuit.

What causes still malfunction of refrigerating machine KKT?
- H
  hrobinsonAug 20, 2025
  A persistent malfunction in your KKT refrigerating machine could be due to low pressure in the refrigerant circuit, possibly from a refrigerant leak, a dirty dryer in the liquid pipe, a defective pressure relief valve, or issues with the expansion valve. High pressure in the refrigerant circuit, caused by a dirty condenser, a defective fan, high outside temperature, a faulty pressure sensor for condenser control, or a defective frequency inverter, can also be the reason. Locate and seal any leaks, then refill the circuit. Replace the dryer, pressure relief valve, or expansion valve as needed. Clean the condenser, correct any electrical issues, check the fuses, spray the condenser with water, and replace the pressostat or frequency inverter if necessary.

What to do if there is a malfunction of plant/system KKT Chiller?
- E
  Elizabeth WrightAug 26, 2025
  A malfunction in the KKT Chiller plant/system could stem from several causes: power failure asymmetry, over or low voltage, a defective temperature sensor, malfunctions in the Simatic modules, or the chiller simply indicating a 'not ok' status. Check the mains connection and asymmetry relay, inspect the sensor clamp and measure resistance, check the MMC-Card, the 24VDC power supply and fuses, check the fuse, data transfer cable, and overvoltage protection.

Why do compressors 18M1 and 21M1 stop in KKT Chiller?
- R
  Richard RichardsonAug 28, 2025
  The compressors 18M1 and 21M1 in your KKT Chiller might stop because the Klixon/INT69 has tripped or is defective. Check the fuses. Allow the compressor to cool down, and consider cleaning the condenser or improving fresh air supply. If necessary, replace the Klixon/INT69.

What causes malfunction of pump 17M1 in KKT KSC Chiller?
- L
  Lori MaloneSep 1, 2025
  A malfunction of pump 17M1 in your KKT Chiller may occur due to several reasons: the main switch not being switched on, a defective motor protector, a blown fuse for the control current, a defective pump motor, the flow switch responding, or a shortage of water. Switch on the main switch. Replace the motor protector. Replace the fuse. Replace the complete pump. Check the water flow and system pressure, and clean the strainer.

Why KKT KSC pump makes gurgling noise?
- A
  Alexis RamirezSep 5, 2025
  If the KKT Chiller pump is making a gurgling noise, it is likely that the circuit is not completely vented. Vent the system and fill it up with water/Ethylene glycol.

What to do if KKT KSC has leaking slide seal?
- C
  Carol HarrisSep 8, 2025
  If there is a puddle at the bottom of the KKT Chiller pump due to a leaking slide seal, it could be caused by air on top of the pump or dirt in the water circuit. Check the air vent on top of the pump and change the pump if necessary. Flush and clean the water circuit, then refill it with a new 35-38vol% water ethylene glycol mixture.
