Chiller is a kind of water cooling equipment, is able to provide constant temperature, constant current, constant pressure cooling equipment. Cold water machine the principle is to a certain amount of water injection machine of the internal water tank, through the mechanism of cold water cooling system will be water cooling, and then have the machine within the cryogenic frozen water injection pump need to cooling equipment, cold water machine the internal heat away, the high temperature cooling of the hot water back into the water again, so exchange cooling cycle, as the function of the cooling equipment.

The Asia-Pacific pump industry rotary submersible sewage pump was successfully developed
Jiangsu Asia Pacific Pump Co., Ltd. has successfully developed the fourth generation of submersible electric pumps, introducing two new series: DA and DAS. These cyclone submersible sewage pumps represent a major advancement in design and performance. Unlike traditional models, these pumps integrate the motor and pump body into a single unit, resulting in a compact and space-saving structure. This not only makes installation faster and more efficient but also simplifies the civil engineering required for pump stations, reducing overall construction costs by 30% to 40%.
The company has introduced a unique swirling impeller design that creates a vortex within the wide chamber of the pump. This innovation allows for the smooth passage of large particles and debris, significantly minimizing the risk of clogging and entanglement, and boosting pumping efficiency by over 30%.
To further enhance reliability, the pumps are equipped with advanced double-face mechanical seal technology, ensuring no leakage even under harsh conditions. The system is controlled automatically via a control panel and an underwater float switch, enabling water level regulation without the need for an additional control system. The pump can operate automatically and also supports parallel operation for greater flexibility.
Inside, it features an internal automatic protection system that detects overload, phase loss, short circuits, water ingress, and overheating. In such cases, the pump will automatically shut down to prevent damage and ensure safe operation. This combination of innovation, efficiency, and safety makes the DA and DAS series ideal for a wide range of wastewater management applications.
