Features
    Microcomputer Control
  • Bilingual interface (Chinese–English or Chinese–Russian) for easy switching.
  • Temperature stability is maintained between ±1°C and ±2°C.
  • User-friendly operation with an intuitive status display.
  • High-quality components from Schneider Electric (France) and Siemens (Germany) ensure reliable performance and long service life.
    Wide Range of Applications and Low Maintenance
  • Air-cooled finned condensers operate efficiently in a variety of environments and are easy to install, clean, and maintain.
  • No cooling tower or external water pump is required, as heat is removed solely through ambient air. This reduces water usage, minimizes maintenance requirements, and achieves a high coefficient of performance (COP).
    Space-Saving and Flexible Installation
  • Our air-cooled scroll chillers feature a compact design that can be installed on rooftops or in confined spaces, saving valuable floor space.
  • We offer both open and closed cabinet models to suit different site requirements, and some models are equipped with casters for easy mobility.
Typical Applications
  • Ideally suited for cooling molds in injection molding and extrusion processes, helping shorten production cycles and producing smoother, higher-quality product surfaces.
  • Maintain stable operating temperatures in laser cutting machines and vacuum coating equipment, protecting precision components and ensuring reliable performance in electronic and semiconductor devices.
  • In the chemical and pharmaceutical industries, air-cooled scroll chillers control the temperatures of reactors and crystallization processes, maintaining process stability and ensuring consistent product quality.
  • Ideal for maintaining a constant temperature for laboratory equipment such as mass spectrometers and nuclear magnetic resonance systems, ensuring accurate and repeatable test results.
  • Suitable for battery production lines and casting processes in the new energy and automotive industries, improving cooling efficiency, accelerating production, and enhancing product reliability.
  • Support cooling in shopping malls, hotels, and other large buildings, with the option of multiple units working together to increase cooling capacity.

Air-cooled chillers adapt well to a wide range of operating conditions. They are easier to install, require less maintenance, and can be used in many applications. However, for the same cooling capacity, their material cost is usually higher compared to water-cooled models.

Water-cooled chillers are more suitable when there is a stable water supply, good water quality, and ambient temperatures below 45 °C. They generally offer better cooling performance, lower energy consumption, and quieter operation. Their overall cost can be slightly lower, but installation is more complex as they require a cooling tower and water pump. Cleaning and servicing the shell-and-tube condenser also calls for trained technicians.

We operate under a strict ISO management system that oversees every stage of production. Quality checks are applied to all incoming materials, manufacturing processes, and testing stages. Customers may arrange third-party inspections before delivery as well to make sure that the chiller is working smoothly.

The main components we use for our chillers are sourced from well-known international brands to ensure long-term reliability. Skilled technicians with advanced welding certifications handle critical processes. Our products are CE certified and exported to over 100 countries, backed by strong customer feedback.

We are manufacturers. We have two production bases plus two component-processing plants. All design, production, and sales are handled in-house. We can customize non-standard chillers or develop tailored solutions according to client requirements, offering both OEM and ODM services.

For medium to large scale facilities, the cooling demand is greater, and the cooling equipment must operate continuously without interruptions. In such cases, screw chillers are often the best option. Depending on site conditions, you might consider a water-cooled screw chiller for higher energy efficiency where water supply is stable, or an air-cooled screw chiller for easier installation and lower water usage.

In sites where there’s limited space, scroll chillers are an excellent choice. Their compact design allows them to fit into smaller areas while still providing reliable cooling performance, making them ideal for small-scale or space-restricted installations.
