Equipped with accurate frost detection for fast defrosting. It lowers defrost cycles and cuts down defrosting duration effectively.
Supports mobile APP control, remote operation, fault alarm and online troubleshooting.
Adopts high-efficiency shell-and-tube heat exchange technology. Built-in water side heat exchanger and flow protection, delivering an outstanding energy efficiency ratio.
Versatile for multiple uses, including radiator heating, underfloor radiant heating, and central air conditioning cooling & heating.
Commercial air cooled modular chiller
Air source heat pump is an energy-efficient equipment that transfers heat from ambient air to high-temperature heat sources.
GRAD air source heat pump and air cooled chiller are high-efficiency HVAC solutions with 20 years of field application experience. Equipped with low-temperature heating, anti-freezing, intelligent defrosting and automatic control technologies, our units deliver reliable performance and wide adaptability.
Suitable for hotels, commercial buildings and various industrial sites, our diversified products meet customized air conditioning requirements for commercial and industrial use.
Air cooled modular unit operates based on the refrigeration cycle. In cooling mode, the refrigerant absorbs heat from circulating water, then the outdoor fans blow air over the condenser to release heat into the atmosphere. When switching to heating mode, the four-way valve reverses the refrigerant flow. The unit captures heat from outdoor air and delivers it to the water system for indoor heating. Each module runs separately or in combination, ensuring stable operation and flexible capacity regulation.
Product Advantages
No dedicated room required, lower upfront investment
Compared with boilers and water-cooled chiller units, this unit can be installed outdoors directly. There is no need to build a separate equipment room, install cooling towers, drill wells or lay buried pipes, effectively cutting customers’ initial capital costs.
High energy efficiency, eco-friendly and safe
The air-source heat pump chiller absorbs abundant heat energy from ambient air for operation, delivering outstanding energy-saving performance. It reduces power consumption by up to 75% compared with electric heating systems.
Adopting R410A eco-friendly refrigerant with an ozone depletion potential of zero. Unlike traditional boilers, it involves no combustion or exhaust emissions, and eliminates flammable and explosive risks.
Modular design for flexible combination & wide application
Featuring modular construction, the system supports linkage of up to 16 modules to match cooling/heating load requirements of various buildings.
Easy capacity expansion allows phased investment for greater cost flexibility.
Wide operating range & strong environmental adaptability
It operates stably for heating at ambient temperatures from -30℃ to 25℃, and runs reliably for cooling within -30℃ to 48℃.
