How To Choose Water Cooled Scroll Chiller and Water Cooled Screw Chiller

A water cooled chiller is a water to water cooled chiller,which is a type of industrial chiller that its use of water as a cooling medium. It circulates the water through the chiller system to absorb heat from the process or equipment that needs to be cooled. The heat is then transferred to the condenser where it is dissipated into the surrounding environment.Choosing the right water cooled chiller is critical for energy efficiency and operational performance.When deciding between a water-cooled scroll chiller and a water-cooled screw chiller, factors like cooling capacity, energy consumption, and application requirements must be considered. This guide will help you make an informed decision.  

What are the Key Differences Between Water Cooled Scroll and Screw Chillers ?

1. Compressor Type  

  - Water Cooled Scroll Chiller: Uses scroll compressors like Panasonic/Danfoss/Copeland Brand, ideal for small to medium cooling loads (2-60 tons). Compact, quiet, and low maintenance.  

  - Water Cooled Screw Chiller: Equipped with screw compressors like Hanbell/Bitzer Brand, suitable for medium to large cooling demands (30-200+ tons). Higher efficiency for heavy-duty applications.

                  Water Cooled Scroll Chiller                                                    Water Cooled Screw Chiller 

2.Evaporator/Heat exchange Type

  - Water Cooled Scroll Chiller: built with water tank and water pump inside the chiller , the evaporator for scroll chiller can be coil in water tank /SS plate type /shell and tube for optional.

  - Water Cooled Screw Chiller:it without water tank and water pump, the evaporator for screw chiller just can be shell and tube.

3. Energy Efficiency

  - Water Cooled Scroll chillers offer good efficiency for smaller systems.  

  - Water Cooled Screw chillers provide superior COP (Coefficient of Performance) for large-scale cooling, reducing long-term energy costs.  

3.Application Industries

  - Water-cooled scroll chillers are commonly used in:

    - Plastic injection molding  

    - Laser cutting machines  

    - Food & beverage processing  

  -  Water-cooled screw chillers are preferred for:  

    - HVAC systems  

    - Large commercial buildings  

    - Pharmaceutical manufacturing  

    - Chemical processing plants  

    - Data center cooling  

How to Select the Right Water Cooled Chiller?

- Cooling Capacity: Calculate the required tonnage based on heat load.  

- Energy Consumption: Screw chillers are more efficient for high-capacity needs.  

- Space & Installation: Scroll chillers are more compact for tight spaces.  

- Maintenance & Lifespan: Screw chillers have longer lifespans but require more maintenance.  

- Budget: Water cooled scroll chillers have lower upfront costs, while water cooled screw chillers offer better ROI for large operations.  

Whether you need a water-cooled scroll chiller for precision cooling or a water-cooled screw chiller for industrial-scale applications, understanding your requirements is key. Evaluate cooling needs, energy efficiency, and industry-specific demands before making a decision.
