Coolant filtration includes two main categories: mobile and industrial. In mobile application, coolant filters protect your engine by trapping contaminants and distributing supplemental coolant additives into your cooling system. With today’s diesel engines putting out more heat, cooling system care has become even more important than before. Your engine coolant battles rust, scale formation, acidity, foaming, silicate drop out and debris while it works to transfer heat and maintain the right operating conditions for optimal fuel economy.
In industrial application, metal working fluids are vital in the metalworking, rolling and wire drawing industries. They provide lubrication, cooling and flush away metal particles from the machines. The process generates metal particles and contaminated the coolant which have be filtered to extend the coolant service life, and reduce the cost of the manufacturing process. Different coolant filtration systems are applied in the industry, such as gravity system, vacuum system, pressure belt system, and hydraulic system, etc.
Nonwovens are widely used as filter media for coolant filtration in mobile and filtration applications.
