Air-cooled and water-cooled chillers differ mainly in how they dissipate heat. Air-cooled chillers use ambient air to remove heat through condenser coils and fans. They are compact, easy to install, and suitable for locations without a steady water source. Maintenance is simpler since they don’t require cooling towers, pumps, or water treatment systems. However, their performance can be slightly affected by high outdoor temperatures.Water-cooled chillers, on the other hand, use water from a cooling tower to condense refrigerant and discharge heat. They offer higher energy efficiency and stable operation, especially in large-scale or constant-load industrial applications. Yet, they require more complex installation, a reliable water supply, and regular maintenance of water circuits to prevent scaling or corrosion.Aurashu provides both types, allowing clients to choose based on project scale, climate, water availability, and energy goals. Each system is optimized for long-term reliability, low noise, and high efficiency.
