The CHS Series is a compact air-cooled chiller and heat pump solution using natural R290 refrigerant, designed for applications requiring efficient cooling, heating, and quiet operation. With cooling capacities from 4.5 to 20.7 kW, the CHS Series combines high energy efficiency, wide operating range, and integrated design to support residential, commercial, and light industrial applications.
The CHS Series air-cooled chillers are designed to deliver reliable cooling and heating performance within a compact footprint. Covering a cooling capacity range from 4.5 kW to 20.7 kW, the series retains full heat pump functionality, making it suitable for applications with year-round demand for both cooling and heating.
Using the latest R290 natural refrigerant (GWP = 3), the CHS Series complies with the Ecodesign Directive and significantly reduces environmental impact associated with energy consumption. This future-oriented refrigerant choice ensures both regulatory compliance and long-term sustainability.
Thanks to its dual-temperature operation capability, the CHS Series can operate reliably in demanding environments, providing:
Heating operation at outdoor temperatures down to –25°C
Cooling operation at outdoor temperatures down to –15°C
This flexibility expands the application scope of the product, making it suitable for industrial dehumidification, data room cooling, agricultural warehouse climate control, and other environments requiring stable and efficient temperature management.
The CHS Series is engineered with a focus on energy efficiency, system integration, and ease of installation. With optimized system design, the units achieve strong seasonal performance indicators:
Heating efficiency: SCOP ≥ 4.6
Cooling efficiency: SEER ≥ 5.1
The system supports flow temperatures up to 75°C, enabling compatibility with a wide range of heating applications. Stable heating performance is maintained even under low ambient conditions, ensuring reliable operation throughout the year.
To reduce installation complexity and operating costs, the CHS Series features multi-component integration, including:
Built-in circulation pump
Dual electronic expansion valves
Energy-saving DC fan
Integrated color touch screen
These integrated components minimize on-site installation work and simplify system commissioning. In addition, the built-in touch screen and multi-way remote control capability allow operators to manage the system efficiently while reducing daily operating costs.
With its low operating noise, compact structure, and compliance with ErP Eco-design standards, the CHS Series provides a balanced solution that combines performance, efficiency, and environmental responsibility in one platform.
