Does the unit require a cooling tower or boiler?

Aurashu screw type air-cooled chiller & heat pump units adopt an air-cooled heat exchange design, where heat is rejected directly to the ambient air through high-efficiency condenser coils and axial fans. During cooling operation, the system absorbs heat from chilled water and releases it into the outdoor air, completely eliminating the need for a cooling tower, cooling water pumps, make-up water systems, or complex water treatment equipment.

When operating in heating (heat pump) mode, the unit extracts thermal energy from outdoor air and transfers it to the heating water system. This process replaces the function of a traditional boiler, meaning no gas, oil, or electric boiler is required. Aurashu heat pump configurations are optimized with enhanced vapor injection, intelligent defrost control, and wide ambient temperature adaptability, enabling stable heating performance even in low outdoor temperatures.

By removing cooling towers and boilers, the system offers multiple benefits:

Lower initial investment

There is no need to purchase or install cooling towers, boilers, water tanks, or related auxiliary equipment, significantly reducing system capital cost.

Simplified installation and space savings

The unit is typically installed on rooftops or outdoor ground areas. This is especially advantageous for projects with limited plant room space, renovation projects, or buildings where cooling towers are restricted by planning regulations.

Reduced maintenance and operating costs

Cooling towers often require frequent cleaning, water treatment, and corrosion prevention. Boilers require fuel supply, safety inspections, and emissions management. Aurashu air-cooled systems avoid these issues, resulting in simpler maintenance and lower lifecycle costs.

Water-saving and environmentally friendly

Since no cooling water is consumed, the system is ideal for water-scarce regions and projects aiming for green building certifications.

High system reliability

Fewer auxiliary components mean fewer failure points. Aurashu units integrate intelligent control systems that monitor compressor operation, airflow, refrigerant status, and safety protections in real time.

Aurashu designs these units with modular or custom configurations, allowing them to serve a wide range of applications such as commercial buildings, industrial facilities, hospitals, data centers, hotels, and large residential complexes. The air-cooled design also ensures compliance with regions where water-cooled systems are restricted or impractical.

In summary, Aurashu screw type air-cooled chiller & heat pump units operate as standalone cooling and heating solutions, requiring neither a cooling tower nor a boiler, while delivering reliable, energy-efficient, and environmentally responsible performance.
