The Penray Companies has introduced a new line of heavy-duty coolant filters featuring synthetic media. The new filters include triple-layer engineering and incorporate Penray’s exclusive Need-Release technology, which introduces coolant additives and fortifiers on an as-needed basis, stabilizing the coolant for optimum effectiveness.

Penray also offers synthetic media filters for use with Extended Life Coolants (ELCs).

The new Penray synthetic media coolant filters are designed to last up to 150,000 mi., 15 months, or 3,000 operating hours. They are fully compatible with conventional coolants as well as new-generation Extended Life Coolants (ELCs). They are available for all popular class 6-8 vehicles, as well as for many mobile off-highway and marine applications.

The filters feature Penray’s fiberglass-based filtering media in a design that provides exceptional filtration, even in extreme operating conditions, Penray said. This design is built on a structural steel screen with an epoxy coating that provides a durable foundation which is wrapped in a non-woven sheet of polyester. All this is encased in Penray’s new fiberglass filtration media.

Unlike time-release filters, which distribute additives at fixed time intervals even when not needed, Penray’s Need-Release filters incorporate “smart” technology. Penray’s Need-Release filters include 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 introduction of these new synthetic media coolant filters assures superior filtration for the long service intervals that are becoming common in heavy duty fleet maintenance,” said Sarah Cooper, product manager. “This new construction is the perfect complement to our time-tested Need-Release technology, which meters supplements and fortifiers on an as-needed basis rather than on a fixed and often ineffective time-based interval as is the case with other designs. The smart technology of our Need-Release chemistry assures that a vehicle’s coolant will maintain the proper efficacy for an extended period of time and use, minimizing down time and maintenance costs and enhancing vehicle productivity.”
