1. What exactly is an "Integrated" Water-Cooled Chiller?

It is a skid-mounted system that combines the chiller, chilled water pump, cooling water pump, water tank, piping, valves, and control system into one pre-assembled unit.

2. How does this differ from a traditional chiller plant?
Traditional systems require separate sourcing and on-site installation of pumps, pipes, and controls. Our integrated unit is "plug-and-play," significantly reducing installation time and engineering complexity.

3. What are the main components included on the skid?
The skid includes the compressor (screw or scroll), shell-and-tube evaporator/condenser, circulation pumps, expansion tank, water flow switches, and the central control panel.

4. Does this unit require a cooling tower?
Yes, as a water-cooled system, it requires a connection to an external cooling tower (unless specified as an evaporative integrated model). We can supply a matching cooling tower upon request.

5. What are the primary applications for this unit?
It is ideal for plastic injection molding, electroplating, chemical processing, pharmaceutical manufacturing, HVAC for commercial buildings, and data center cooling.

6. Can this unit be installed outdoors?
Standard units are designed for indoor plant rooms (IP44). However, we offer IP55/IP65 weather-proof housing options for outdoor roof or ground installation.

7. What refrigerant options do you offer?
Standard units use R407C or R410A. We also offer eco-friendly options like R134a and low-GWP refrigerants like R1234ze upon request.

8. Is the unit factory tested?
Yes, every unit undergoes a full-load run test at our factory before shipment to ensure all hydraulic and electrical components function correctly.

9. What is the expected lifespan of the unit?
With proper maintenance, the design life is 15–20 years.

10. Do you offer explosion-proof models?

11. What is the cooling capacity range available?
Our integrated series ranges from 10 tons (35 kW) up to 200 tons (700 kW) per single skid.

12. What type of compressors are used?
Smaller units typically use Scroll compressors (Danfoss/Copeland), while larger units use Semi-Hermetic Screw compressors (Hanbell/Bitzer).

13. Can the system handle variable loads?
Yes, screw compressor models feature stepless capacity control (25%-100%), and VFD (Variable Frequency Drive) options are available for precise load matching.

14. What is the standard chilled water outlet temperature?
The standard range is 5°C to 20°C. Low-temperature models (glycol required) can reach -5°C to -30°C.

15. What is the temperature stability accuracy?
Standard units maintain ±1°C. Precision models can achieve ±0.5°C or better.

16. What voltage supply is required?
Standard is 3-phase, 380V/50Hz. We can customize for 220V/60Hz, 440V/60Hz, or 480V/60Hz for different regions.

17. Are the pumps stainless steel?
Yes, the wetted parts of the integrated pumps are typically Stainless Steel 304 to prevent rust and corrosion.

18. What is the noise level of the unit?
Noise levels vary by size but generally range between 65 dB(A) and 80 dB(A). Sound-attenuating enclosures are available.

19. Does the unit use a shell-and-tube or plate heat exchanger?
We use Shell-and-Tube for condensers (better for water quality tolerance) and either Shell-and-Tube or Brazed Plate for evaporators, depending on the model size.

20. What is the Energy Efficiency Ratio (EER/COP)?
Our water-cooled units typically achieve a COP between 4.5 and 5.8, depending on operating conditions and compressor type.

21. How much floor space can I save compared to a traditional system?
You can save approximately 30–40% of floor space since pumps and valves are compactly arranged on the skid.

22. Do I need a special concrete foundation?
A flat, level concrete pad capable of supporting the unit's operating weight is sufficient. Anti-vibration pads are recommended.

23. What piping connections need to be made on-site?
You only need to connect:

1. Chilled water supply & return.

2. Cooling tower water supply & return.

3. Make-up water line.

24. How is the unit transported?
It is shipped as a single crate/skid. It includes lifting lugs for crane lifting and a base frame suitable for forklifts.

25. Does the unit require a dedicated machine room?
No, because it is self-contained and quiet, it can often be placed near the production equipment, reducing piping runs.

26. What size are the water connections?
Connection sizes range from DN25 (1 inch) to DN200 (8 inches) depending on capacity. Flange or thread connections are available.

27. Do I need to install an external water tank?
The unit typically includes a buffer tank. However, for very large water volume systems, an external tank might still be beneficial.

28. How far can the cooling tower be from the unit?
The integrated pumps have a specific head pressure (e.g., 20m–30m). If the tower is very far or high, we may need to upgrade the pump on the skid.

29. Is a bypass valve included?
Yes, a manual or automatic bypass valve is often included to protect the evaporator from low flow.

30. Can I stack these units?
No, these units are not designed to be stacked vertically. They must be placed side-by-side.

31. What brand of PLC/Controller is used?
We standardly use Siemens, Punp, or Schneider PLC systems.

32. Is the interface user-friendly?
Yes, it features a 7-inch or 10-inch color touchscreen with multi-language support (English, Spanish, Chinese, etc.).

33. Can I connect this to my Building Management System (BMS)?
Yes, the controller supports Modbus RS485 communication protocol. BACnet is available as an option.

34. Does it have remote monitoring capabilities?
Yes, optional IoT modules allow you to monitor temperature, pressure, and alarms via a mobile app or web browser.

35. What happens if the power fails?
