Water chiller

1:The compressor unit adopts vortex type hermetically sealed compressor and electric control components, and is equipped with condenser and evaporator made of high quality copper tube for heat transfer and high efficiency.

2:CDOCAST water chiller Equipped with all kinds of safety protection devices, stable performance, low noise, long service life, simple operation; the use of liquid crystal display man-machine interface, simple and convenient operation, operating conditions at a glance.

3:The water chiller  are equipped with single compressor or multi-compressor combined refrigeration system. The compressor can automatically alternate the operation according to the load change and balance the running hours of each compressor to save energy and extend the service life of the chiller set. It is convenient for energy adjustment and more energy-saving at partial load.

4:the whole water chiller designed with shell box structure & attractive appearance &compact structure, the chiller can be checked at any time; the chiller comes with its own water tank and circulating water pump according to the cooling capacity, without the need for installation of  cooling tower and cooling water pump, installation and maintenance is simple and convenient.

1. Why is our water chiller more expensive than others?

Our chillers use a Siemens control system, which offers key advantages:

• High Reliability & Stability: Siemens PLCs and touchscreens are built for harsh industrial environments, resisting interference, vibration, and temperature/humidity changes.
• Precise Temperature Control: Advanced algorithms (e.g., PID) enable accurate control, with fluctuations as low as ±0.1°C to ±0.3°C.
• Energy Efficiency: The system dynamically adjusts compressor, pump, and fan speeds based on cooling demand, optimizing performance and reducing waste.

2. What determines the cooling effect of a water chiller?

Cooling capacity depends on how much heat is removed from the source and dissipated into the environment per unit of time.

• Water Tank (10% role): Provides thermal buffer and stability. A larger tank slows temperature changes and reduces compressor cycling, but does not generate cooling.
• Refrigeration System (90% role): Performs the actual heat transfer:

• • Compressor: The “heart” of the system; its power defines max cooling capacity.
  • Evaporator: Absorbs heat from the circulating water.
  • Condenser & Fans: Release absorbed heat into the atmosphere.

3. Why do you use stainless steel tanks instead of cast iron?

4. What is the service life of a water chiller?

• Running 24/7: Refrigerant may need replacement after 6–7 years.

• Running 2–3 hours/day: Refrigerant may last about 10 years.
  Lifespan depends on maintenance. Avoid use in strongly acidic/alkaline environments or outdoors without protection.

5. What spacing is needed between multiple chillers?

• Keep 1–1.5 meters between units.

• If placed near a wall, maintain 0.8–1 meter clearance for proper ventilation.

6. What causes frequent high-temperature alarms?

• Room too small, poor heat dissipation.

• Solution: Move chiller outdoors (with rain cover) or install fans outside.

• Change tank water every 2–3 weeks, especially when cooling precious metals like gold/silver.

7. Is higher pump pressure better?
No. Excessive pressure strains the pump, risking burnout. Too low pressure reduces water flow and cooling efficiency.

8. Is a higher pump power better?
No. Overpowered pumps can cause pipe bursts or system damage.

9. How do you match chiller models to different machines?
We select based on machine power, usage frequency, and operating environment. Please provide these details before purchase.

10. Can anti-freeze fluid be used in your chillers?
Yes, our chillers support the use of anti-freeze fluid.
