Incorporated in 1950, The Penray Companies continue to grow strong after 50 years of service in the heavy-duty and automotive chemical industry. There are two main plants where we manufacture both liquids and aerosol products. They are in Elk Grove Village and Wheeling Illinois. Penray is comprised of four separate business units: heavy-duty, automotive, export, and custom manufacturing. The heavy-duty division is known as Power Fleet. This division markets the Pencool® brand engine coolant products. These products are the most respected in the industry and include antifreeze inhibitors, supplemental coolant additives (SCAs), diesel fuel additives, and the advanced Need-Release® extended service interval coolant filters.The automotive division manufactures and markets three lines of products. The first, Performance Products, is marketed under the Penray brand, and is engineered for use by professional maintenance and repair technicians. The Super-X® brand is packaged with the retail, do-it yourself customer in mind. Finally, JetGo® is geared for the convenience store. All three lines offer high quality products and eye-catching packaging. They are regarded as high quality product lines in the industry and have loyal customer followings. Penray exports products to 44 countries worldwide. We offer foreign language labels and catalogs for both the automotive and heavy-duty products. Custom products are also frequently formulated to customers’ requirements.
