Modular Water Cooled Chillers

Modular water cooled chillers is an independent new chilled water production system, which is composed of multiple modular chiller units connected in parallel.

As an efficient and cost-effective alternative to traditional chillers, equipment components are pre-engineered and manufactured. The module is skid-mounted, pre-piped, wired, tested and shipped to the job site where water and electrical connections are made.

Several advantages of modular water cooled chillers.

1. Save energy consumption

Modular chiller pipe lengths and fittings are reduced, saving both money and pump energy.

2. Equipment installation safety

The chilled water system is installed in a clean and easy-to-control environment, and is hoisted and assembled through overhead, lifting and other equipment. Due to the modular components, the safety of the entire installation project is enhanced.

3. Avoid current shock during module startup process

Since each module in the modular unit is started sequentially, the starting process will reduce the impact of current on the power grid compared with conventional large-scale refrigeration machines with the same cooling capacity.

4. Refrigeration engineering has strong scalability

A variety of cooling devices and system components can be added according to needs, making it more scalable and practical. The maximum cooling capacity of a modular unit is determined by the number of modules. As long as more modules are added, the cooling capacity of the unit can be increased accordingly.

5. Matching and debugging of the whole machine is faster

Modular chillers, such as pipes and connecting parts, only need to be assembled on site. The modular chiller control system has been configured at the factory, which avoids errors and waste of time caused by on-site testing, and directly speeds up the project progress.

Since the unit can be separated into multiple small and light-weight modules for transportation, no special lifting tools are needed. The unit can be transported to the machine room using trolleys and elevators. The savings in lifting costs are considerable.

6. Saves equipment installation space

While a conventionally installed chiller design consumes 1.45 to 1.65 square feet of building space, the same project can save 30 to 35 percent of space using a modular chiller layout.

7. Reduce post-sales service disputes

Traditional chiller project projects require the cooperation of contractors. Chillers, pipelines, valves, and electrical installations are complex. Once a problem occurs, each contracting manufacturer needs to inspect the unit on-site. However, modular chillers are manufactured by equipment. The supplier is fully responsible for the refrigeration unit system to avoid disputes.

8. Reduce the total project cost

Due to the characteristics of the modular chiller, it can save installation time, reduce investment in manpower and material resources, control project time and cost, and save project funds.

9. More convenient for later maintenance and repair work

The module has a simple structure, and the technical difficulty of installation and maintenance is low. It is even simpler than the maintenance of air conditioners and industrial wind cabinet units. If a module fails, it can be separated from the unit for repair, which reduces subsequent maintenance costs.

10. The equipment has low vibration and low noise.

Modular water cooled chillers use a fully enclosed refrigeration compressor with small vibration and low noise, and the frame is vibration-isolated and the box wall is silenced, making the installation location of the modular unit more flexible, instead of being installed in a special place like conventional chillers. In the computer room.

12. Convenient for batch and intelligent production

The modular chiller has a simple structure, a high degree of commonality of parts and components, and its manufacturing process is streamlined and intelligent, which is conducive to mass production and reduces production costs for chiller manufacturers.

13. Intelligent operation control, convenient for daily use

Using intelligent PLC/PC operation control, it can not only control the operating number of modules according to the demand for cooling capacity, but also control the alternate operation of each module. In addition, for module failures, the system can judge and record the time of failure and operating conditions by itself. This will facilitate future follow-up inspections by maintenance personnel and shorten maintenance time.

14. Efficient heat exchange device

In the form of modular water cooled chillers heat exchangers, they adopt plate heat exchangers with compact structure and high heat transfer efficiency. Its structural material is stainless steel plate, and the inner surface is pressed with herringbone corrugations, which has the characteristics of removing dirt and low heat transfer resistance. It is made of copper brazing and has a non-detachable structure with good sealing performance.
