The innovative technology is used in a water-based cooling system to cool cabinets, data centers, industrial processes and buildings with the pure natural refrigerant and zero emissions. The inherent system requires a constant and precise vacuum. This is where a customized vacuum pump from the KNF N 813.3 series comes into play. Global Search for Better Refrigerants Most refrigeration systems rely on traditional refrigerants like fluorinated gases (F-gases), ammonia or propane. However, these conventional refrigerants pose threats to the environment, safety, and human health. F-gases contribute to ozone depletion and global warming while ammonia is toxic and propane inflammable. Therefore, there has been a widespread search for safe, clean, sustainable and affordable refrigerants. Pure Water Enables Superior Efficiency and Reduces Emissions The main advantages lie in the technology's outstanding efficiency and sustainability. It enables electricity savings of up to 80 percent compared to current conventional cooling systems and generates almost zero CO2 emissions. Because it uses only water, the technology poses no risk to humans or the environment. Filling the system, service, and maintenance, including the recycling is simple and no need to lean on of safety regulations like the ones used for traditional refrigerants. Cutting-edge Vacuum Pump for Water-based Technology Needed A small footprint and a general high robustness are vital, and the pumps must be able to cope with the challenging steam environment in the chiller. Therefore, diaphragm pump technology is ideal for the task and ultimately led to a collaboration between the system’s manufacturer and KNF, the leader in diaphragm pump technology. The KNF N 813 series model was tailored to meet customer requirements. Specially Customized Vacuum Pump for Water-based Technology Despite its powerful performance and the high motor rotation speed, the vacuum pump operates very quietly and with low vibration. This opens the possibility to use the chiller in residential buildings and in manufacturing processes where low-noise operation is important. This example illustrates how the quality of one component like a pump can have a major effect on the entire system and its applicability for different areas. It also shows that customizing a pump collaboratively can lead to solutions that would otherwise not have been possible. Discover Our Products!
