What The Penray Companies, Inc. does
The Penray Companies, Inc. is a US-based aftermarket specialty chemicals manufacturer founded in 1951 and headquartered in Downers Grove, Illinois. Since 2017 it has operated as a wholly-owned subsidiary of PLZ Corp, a Pritzker Private Capital portfolio company that produces more than 2,500 brand and private label chemical products. Penray formulates, blends, and packages chemical maintenance solutions for four end markets: automotive service professionals, heavy-duty truck fleets and owner-operators, marine operators, and private label/OEM customers. The company maintains 150+ SKUs across its portfolio under recognized sub-brands including Penray Performance (premium professional grade), Super-X (DIY/retail), Pencool (coolant additives), POW-R (diesel fuel treatment), and Fuel Doctor (diagnostic service).
The company's core technology centers on proprietary fuel treatment chemistry and cooling system hardware. Its patented HAFI (Hybrid Anti-Gel Flow Improver) technology (US Patent #8,349,033) is a hybrid polymer system that prevents diesel fuel gelling, reduces cold filter plug point by up to 30°F, and is ULSD-compliant and biodiesel-compatible. Its patented Need-Release cooling system filter extends coolant service intervals to 150,000 miles and anchors the Fill-For-Life extended service interval program. Penray also operates the Fuel Doctor Program, a fuel testing and analysis service that delivers customized treatment plans for diesel fuel storage systems. The company holds multiple VOC-compliant brake cleaner formulations to address state-level regulatory restrictions.
Penray generates revenue through three primary streams: branded product sales (fuel additives, coolant treatments, brake cleaners, lubricants, specialty chemicals), private label/custom manufacturing for aftermarket and OEM service organizations (full-service from formulation through packaging), and export sales to over 20 countries. Go-to-market is executed via a multi-channel distribution model: 80 independent Penray Power Fleet Warehouse Distributors, OEM dealer networks (Kenworth, Peterbilt, Navistar, Freightliner, Detroit Diesel), private label supply agreements (including exclusive supply to the Aftermarket Auto Parts Alliance), Amazon for SMB/consumer reach, and direct regional sales manager coverage. Pricing is not publicly disclosed and operates on B2B quote/distributor terms. The company employs 101-250 people.
