The glass fiber-based filtering media is incorporated into a triple-layer design which is built on a structural steel screen with an epoxy coating and wrapped in a nonwoven sheet of polyester. The triple-layer construction allows these new filters to achieve high levels of filtering efficiency and capacity for up to 150,000 miles, far longer than other filters with conventional paper filtration media, according to Penray.
The filters also feature Penray’s Need-Release technology which includes a membrane that senses deterioration in the coolant chemistry, and responds by releasing one of its four charges of additives and fortifiers to restore coolant chemistry. Over time, as key components of the coolant are depleted, the Need-Release technology releases additional charges of supplements to again restore the coolant to viability. This process continues over extended periods of time until all four charges have been released.
The filters are designed to last up to 150,000 miles, 15 months, or 3,000 operating hours and are compatible with conventional coolants or new-generation extended life coolants (ELCs). They are available for all class 6, 7, and 8 vehicles, as well as for many mobile off-highway and marine applications.
In addition, many of these new synthetic-based coolant filters feature Penray’s exclusive Need-Release technology. Unlike time-release filters, which distribute additives at fixed time intervals even when not needed, Penray says its Need-Release filters incorporate “smart” technology.
