A Natural Cooling Air-Cooled Screw Chiller is an advanced refrigeration system that integrates both mechanical compression and natural cooling (also known as “free cooling”) to achieve efficient temperature control and energy savings. Unlike traditional air-cooled chillers that rely solely on compressors for cooling, this system intelligently utilizes ambient low temperatures—especially during cooler seasons—to partially or completely replace compressor operation, significantly reducing power consumption.The unit features high-efficiency screw compressors, air-cooled condensers, and a built-in free cooling module equipped with finned coil heat exchangers and intelligent three-way control valves. When the outdoor temperature drops below a certain threshold, the system automatically switches to natural cooling mode. In this mode, cold ambient air directly cools the process water or glycol solution through the heat exchanger, minimizing compressor load while maintaining stable outlet water temperature.Aurashu’s Natural Cooling Air-Cooled Screw Chiller adopts intelligent dual-mode control, seamlessly switching between mechanical and natural cooling modes based on real-time ambient conditions and system demand. This enables energy savings of up to 30–50% annually, especially in regions with long cold seasons. Additionally, it features modular configuration, low noise operation, eco-friendly refrigerants (R134a/R1234ze), and a fully digital monitoring system for precision management.These chillers are widely used in data centers, pharmaceuticals, electronics manufacturing, industrial processing, and other facilities requiring reliable year-round cooling. By reducing compressor runtime and energy usage, they also extend equipment life and lower carbon emissions, helping users meet both economic and environmental sustainability goals.Aurashu provides tailored natural cooling solutions according to customer needs, ambient temperature ranges, and process requirements—ensuring optimal system performance, energy efficiency, and reliability in all operating conditions.

Yes. Aurashu modular air-cooled chillers are designed with intelligent control systems that automatically adjust capacity according to actual load demand. Each module operates independently but is coordinated through a centralized control network. When cooling or heating demand decreases, the system can shut down unnecessary modules and operate only the required ones, achieving energy-saving part-load operation. Conversely, when the load increases, additional modules are automatically activated to ensure stable performance. This staged modulation minimizes power consumption, reduces compressor wear, and extends service life. Equipped with advanced microprocessor or PLC controllers, the system continuously monitors temperature, pressure, and flow parameters, optimizing performance through real-time data analysis. Compared with traditional single-unit chillers, modular systems can achieve higher energy efficiency ratios (EER) under partial load conditions—often improving overall efficiency by 15–30%. This intelligent load-matching capability ensures reliable comfort control and cost-effective operation in all seasons.

No — in fact, modular design enhances system stability. Each module in Aurashu’s modular air-cooled chiller unit operates as an independent system with its own compressor, condenser, evaporator, and control circuit. When combined, these modules communicate through an intelligent control network that balances load distribution, adjusts capacity automatically, and ensures redundancy. If one module temporarily stops for maintenance or fault inspection, the remaining modules continue operating normally, avoiding full system shutdown. This distributed structure minimizes operational risk, improves system reliability, and simplifies maintenance. The modular configuration also ensures smooth startup, balanced energy output, and longer equipment lifespan. Moreover, Aurashu’s advanced control algorithms continuously monitor temperature, pressure, and performance parameters to optimize stability in real time. Whether in commercial buildings, factories, or data centers, this modular architecture guarantees uninterrupted cooling and efficient, stable operation year-round.

Aurashu’s modular air-cooled cold (hot) water units are designed for flexible configuration and intelligent connectivity. Each module operates as an independent refrigeration system with its own compressor, evaporator, and condenser, but multiple modules can be linked together through a shared water piping network and communication bus. The hydraulic system typically connects modules in parallel using quick couplings and standardized flanges, enabling seamless capacity expansion or reduction as needed.In terms of control, the system adopts an integrated microcomputer or PLC-based centralized control platform. Through a communication protocol (such as Modbus or BACnet), all modules share operational data, automatically balance load distribution, and coordinate start-stop sequencing to achieve optimal efficiency. The master control unit monitors temperature, pressure, and flow in real-time and adjusts each module’s output accordingly.This intelligent linkage allows up to 16 modules to run synchronously, achieving precise temperature control, energy saving, and fault redundancy. It ensures high stability, easy scalability, and smart management for commercial and industrial applications.

The installation of a modular air-cooled cold (hot) water unit is designed to be simple, flexible, and time-efficient. Each module is an independent system that includes a compressor, condenser, evaporator, and control components. Units can be installed outdoors on rooftops or open platforms without the need for a dedicated machine room or cooling tower.Installation begins with preparing a solid, level foundation capable of supporting the unit’s weight and vibration. Modules are then placed in sequence according to the design layout, with refrigerant and water piping connections linked between modules. Electrical wiring and communication cables are connected to ensure centralized control and synchronized operation. Once the modules are connected, the control system automatically identifies each unit, forming a unified network that adjusts output based on load demand.Aurashu provides detailed installation manuals and professional technical guidance, ensuring safe, standardized setup and optimal system performance.

For larger-capacity units, semi-hermetic screw compressors are applied, offering high reliability, continuous duty performance, and adaptability to varying load conditions.Each module of the unit operates with independent refrigeration circuits, allowing partial-load operation and redundancy — meaning one module can undergo maintenance without stopping the entire system. The compressors are compatible with eco-friendly refrigerants such as R410A or R134a, supporting energy conservation and environmental sustainability.Aurashu also integrates intelligent electronic expansion valves and advanced control algorithms to precisely adjust compressor capacity and refrigerant flow, improving overall system performance while minimizing energy loss and extending service life.

Yes. Aurashu’s modular air-cooled units are designed to provide both cooling and heating functions, offering all-season comfort and flexibility. Each module integrates a reversible heat pump system that allows it to switch between cooling and heating modes automatically based on the set parameters or environmental conditions. In cooling mode, the unit absorbs indoor heat and releases it outdoors, while in heating mode, the cycle reverses—extracting heat from the outdoor air and transferring it indoors. This dual-function design eliminates the need for separate heating equipment, saving installation space and reducing system investment costs. The heating efficiency (COP) of the modular units can reach up to 3.5 or higher, depending on ambient temperature and system configuration. Aurashu’s intelligent control system ensures stable operation even in low-temperature environments, making the unit ideal for regions with variable climates. This system provides energy-efficient year-round performance with high reliability and user comfort.

A modular chiller differs from a standard air-cooled chiller mainly in structure, scalability, and operational flexibility. A standard air-cooled chiller is a single, integrated unit designed for fixed cooling capacity, suitable for medium to large-scale applications with steady load demands. In contrast, a modular chiller system consists of multiple independent modules that can operate individually or together, allowing for flexible capacity expansion and higher system redundancy. Each module includes a complete refrigeration cycle, enabling the system to automatically adjust its output according to real-time load requirements — achieving greater energy efficiency and reliability. Modular chillers are easier to transport, install, and maintain, making them ideal for projects requiring phased construction or future capacity upgrades. Additionally, their distributed design reduces downtime risk — if one module requires service, others can continue running. Aurashu’s modular chillers integrate intelligent control and networking functions for smart, efficient, and scalable cooling management.
