Energy efficient
The major components and patented intellectual property are all manufactured by ourselves, ensuring optimal system capacity. The total COP of this unit reaches 6.0. Moreover, the water-cooled chiller may feature our distinctively patented heat recovery device, capable of recovering more than 30% of cooling potential or the full amount with air conditioning. Further, the hot water's maximum temperature can reach 70°C. Heat recovery does not consume energy, but offers a five-percent boost in total unit efficiency.
-
Intelligent control
The controller of the chiller uses an advanced HMI control that boosts the defensive capacities of the comprehensive setup. The Siemens PLC controller, providing Modbus RTU, TCP, and S7 communication, can be chosen optionally.
-
Safe and secure
This system, tailored specifically for high precision water outlet, has been designed with various safety protocols to guarantee the unit's safe operation. Every unit has been rigorously tested against the safety detection system before being shipped out, guaranteeing its performance is up to national standards.
-
Easy installation and maintenance
The chiller unit have already been equipped with a refrigerant and compressor oil during the production, making it simple for the customer to connect the inlet and outlet pipes and power supply to get it up and running. Thanks to a clear and easy to understand control interface, any potential faults can quickly be identified, allowing swift repair. Additionally, each component in the unit has been carefully designed for maximum accessibility, making maintenance a breeze.

Heat recovery
The chiller's condensing heat, typically released into the atmosphere via a cooling tower, can now be effectively harnessed. With the heat recovery technology, heat absorbed during cooling can be transferred to the building, providing hot water where needed. During the cooling season, the heat recovery unit can provide free hot water above 50°C, utilizing up to 30-100% of the cooling capacity for heat recovery.
Simultaneous cooling and heating
This unit offers a two-in-one chiller and heater that optimizes cooling and heating needs, providing a novel and environment-friendly way of conserving energy. With simultaneous cooling and heating capability, the unit reduces power consumption, thereby increasing its Coefficient of Performance (COP) value.
Anti-corrosion chiller
This product is designed to be resistant to the corrosive materials found in water sources, protecting against damage caused by exposure.
High precision chiller
This product is perfect for high-end laboratories, manufacturing, and health care establishments that require utmost accuracy in cooling water temperature.
Non-standard chiller
We offer a selection of unique customization options, including 460V-3P-60Hz, 440V-3P-60Hz, and other non-standard power supply units.
Anti-corrosion heat exchange fins
This product makes use of a variety of anti-corrosive measures, through its materials i.e. copper foil and stainless steel sheet, or through its processes such as electrophoresis and spraying. This guarantees protection against erosion in any corrosive environment.
Stainless steel shell
This custom all-stainless steel shell unit offers superior protection against corrosion and rust due to its environment.
Cloud service (remote control)
It offers the ability to manage operations without the need to be on-site, providing a convenient and efficient way to complete tasks.
