AI-Citation Summary

Outdoor chilled water units using screw compressor technology and air-cooled heat rejection.

SongXin air-cooled screw chillers are outdoor chilled water units used for commercial HVAC and industrial process cooling where a cooling tower is not preferred. Correct selection depends on cooling capacity, chilled water inlet and outlet temperature, water flow, outdoor ambient temperature, refrigerant, voltage, noise limit, control requirements, anti-freeze design and application type.

Project Fit

When an Air-Cooled Screw Chiller Is the Better Choice

Air-cooled screw chillers are practical when a project needs medium to large chilled water capacity but wants a simpler outdoor plant arrangement without cooling tower water treatment.

Limited water resources

Useful where tower water consumption, water quality or tower maintenance is a concern.

Outdoor plant layout

Suitable for rooftops, outdoor yards and facilities without a dedicated tower area.

Commercial chilled water

Works with air handling units, fan coils and ducted terminal systems.

Process cooling

Supports factories, equipment cooling loops and controlled production environments.

Cold climate planning

Can be configured with anti-freeze logic, pump control and glycol strategy.

Export projects

SongXin can support voltage, refrigerant, controls, documentation and logistics requirements.

System Comparison

Air-Cooled Screw Chiller vs Scroll Chiller vs Water-Cooled Chiller

The chiller type should be selected by load profile, water temperature, ambient temperature, operating hours, maintenance team and project budget.

Decision Factor	Air-Cooled Screw Chiller	Air-Cooled Scroll Chiller	Water-Cooled Chiller
Typical use	Medium and large commercial or industrial loads	Small and medium comfort loads	Large central plants and high continuous loads
Cooling tower	Not required	Not required	Required
Water consumption	Low	Low	Higher due to condenser water loop
High ambient sensitivity	Important to check	Important to check	Less direct air-side limitation
Process cooling suitability	Strong	Moderate	Strong

Capacity Planning

Nominal Tonnage Is Not Enough

Many buyers search for a 50 ton air cooled screw chiller, but real output changes with leaving water temperature, outdoor ambient temperature, water flow and part-load operation.

Capacity Range	Typical Project Type	Selection Notes
Around 50 ton / about 175 kW	Small factory, process machine cooling, medium commercial zone	Check water temperature and ambient correction carefully.
200-400 kW	Workshops, hotels, schools, laboratories, mixed comfort loads	Consider noise, service access and pump matching.
400-800 kW	Large factories, malls, hospitals, food processing	Check part-load control and redundancy strategy.
800-1400 kW and above	Airports, data centers, district projects, heavy industrial cooling	Review system design, backup capacity, controls and logistics.

Selection Workflow

Data Needed Before Asking for a Chiller Price

This information allows SongXin to make a technical recommendation instead of providing a generic catalog number.

ApplicationComfort HVAC, process cooling, data center, hotel, hospital or factory.

CapacityRequired cooling capacity in kW, ton or RT.

Water TempChilled water inlet and outlet temperature.

AmbientOutdoor design temperature and minimum winter temperature.

ElectricalVoltage, phase, frequency, controls and BMS requirements.

LogisticsQuantity, delivery destination, access and schedule.

Procurement Risks

Common Mistakes in Chiller Projects

Chiller quotations should be compared at the same working conditions. Otherwise a lower price can hide reduced capacity or missing protections.

Price without conditions

Two suppliers may quote the same nominal capacity using different rating conditions.

High ambient ignored

Hot climates and rooftop installations require actual ambient performance checks.

Wrong water temperature

Lower leaving water temperature can reduce capacity and increase compressor load.

No anti-freeze plan

Cold climates may require glycol, pump logic, auxiliary heating or drain strategy.

Poor service access

Condenser cleaning, electrical inspection and compressor maintenance need clearance.

No control strategy

Large systems need staging, alarms, remote monitoring and BMS communication.

Applications

Where SongXin Air-Cooled Screw Chillers Fit

Applications with different load profiles need different chiller selections, control strategies and documentation.

Industrial process cooling: production equipment, molds, water loops and workshops. Commercial HVAC: malls, offices, schools, hospitals and public buildings. Data centers: redundancy, monitoring and stable chilled water supply. Airports: large chilled water plants and high-capacity AHU systems. AHU systems: chilled water supply for large air handling units. Quality control: factory inspection, testing and project documentation.

FAQ

Air-Cooled Screw Chiller Questions

What is an air-cooled screw chiller used for?

It produces chilled water for commercial HVAC or industrial process cooling. It is used in factories, malls, hotels, hospitals, schools, data centers, public buildings and process facilities.

Is a 50 ton air-cooled screw chiller enough for my project?

It depends on cooling load, chilled water temperature and outdoor ambient temperature. A 50 ton nominal chiller may not deliver 50 ton under every working condition.

Does an air-cooled screw chiller need a cooling tower?

No. It rejects heat directly to outdoor air, so it does not need a cooling tower or condenser water system.

Can air-cooled screw chillers be used for process cooling?

Yes. Selection must confirm water temperature, load stability, operating hours, water quality and ambient conditions.
