What TRANSTEX does

TRANSTEX is a privately held Canadian-founded cleantech manufacturer that designs and produces fuel-efficiency and emissions-reduction technologies for commercial trucking fleets. The company is headquartered in Montreal, Quebec, with US operating and distribution locations in Indianapolis, Indiana and Laredo, Texas, and a composites manufacturing facility in Harmony, Pennsylvania. TRANSTEX serves Class 8 trucking fleets, trailer OEMs, and dealer networks across North America and internationally in Latin America, Europe, and Australia. Named enterprise customers include Covenant Logistics, CR England, Knight-Swift Transportation, Mesilla Valley Transportation, GP Transco, Nussbaum, National Carriers, Border International, and Intermountain Trailer.

TRANSTEX operates three product platforms. The EDGE line of aerodynamic devices (skirts, flaps, topkits, cab extenders, and the proprietary T-FLEX BLUE BRACKET) reduces trailer and truck drag, with the EDGE ELITE AERO SYSTEM delivering up to 10.5% fuel savings per trailer. The DClimate line provides electric auxiliary power units (the Lithium Pro with a 5.12 KWh LiFePO4 battery and the Day Cab model) that eliminate engine idling for hotel loads. The TRANSTEX COMPOSITES line, established via the July 2024 acquisition of US Liner Company and rebranded in November 2025, supplies fiber-reinforced thermoplastic composite materials (VERSITEX, BXR, BULITEX, SILVERBACK) for trailer interior protection, flooring, and structural applications. The portfolio is supported by 86 patents across six countries, ISO 9001 certification, CARB compliance, and SmartWay verification.

The business model is hardware sales through a multi-tier dealer network combined with direct B2B enterprise sales to large fleets, using a quote-based pricing mechanism. Products have multi-year lifecycles with limited warranties (2-5 years for eAPUs) and aftermarket replacement cycles. Revenue is generated across three streams: aerodynamic products, electric APU systems, and composite materials, the last expanded via inorganic moves including the 2024 acquisitions of DClimate and US Liner Company and the 2026 acquisition of FleetAero assets from Knight-Swift Transportation, which also established a long-term strategic validation partnership.

Revenue model

1. Aerodynamic Products (EDGE Family): Sale of trailer aerodynamic devices including skirts, flaps, topkits, cab extenders, and brackets. Revenue is generated through direct sales to fleet operators and via dealer/distributor network. Products have multi-year lifespans with replacement and upgrade cycles.
2. Electric APU Systems (DClimate): Sale of electric auxiliary power units for heavy-duty trucks. The DClimate Lithium Pro and Day Cab models are sold with limited warranties (2-5 years) and include professional installation. Revenue is one-time hardware sale with potential aftermarket service components.
3. Composite Materials (TRANSTEX COMPOSITES): Sale of thermoplastic composite materials including VERSITEX liner, BXR, BULITEX, and SILVERBACK products. Revenue from OEM supply contracts and aftermarket sales to fleet operators and trailer manufacturers. Expanded via the 2024 acquisition of US Liner Company.

Core offering

TRANSTEX designs and manufactures fuel-efficiency and emissions-reduction hardware for commercial trucking fleets across three integrated product lines: EDGE aerodynamic trailer/truck devices (skirts, flaps, topkits, cab extenders, fins, brackets), DClimate electric Auxiliary Power Units (eAPUs) that eliminate engine idling, and TRANSTEX COMPOSITES fiber-reinforced thermoplastic composite materials for trailer protection, flooring, and structural applications. Products are sold primarily to enterprise Class 8 fleet operators via a North American dealer network, direct enterprise sales, and international distributors.

Product overview

TRANSTEX is a technology solutions provider for the commercial transportation industry, offering a portfolio of idle reduction, aerodynamic, and composite products. The product lineup consists of three main categories: eAPUs (DClimate Day Cab and DClimate Lithium Pro) for idle reduction and auxiliary power; aerodynamics (EDGE product line including CABFLEX, ELITE AERO SYSTEM, ELITE TRUCK SYSTEM, FINS, FLAPS, LATERAL PROTECTIVE DEVICES, SKIRTS, TOPKIT+, and T-FLEX BLUE BRACKET) for drag reduction and fuel efficiency; and composites (VERSITEX, VERSITEX AM, VERSITEX REPAIR KIT, BXR, BULITEX BX, BULITEX HYBRID, Versitex Integral Wall Liner, SILVERBACK, and ENGINEERED SOLUTIONS) for weight reduction and durability. The company expanded its portfolio through acquisitions including US Liner (July 2024, rebranded to TRANSTEX COMPOSITES LLC in November 2025) and FleetAero assets (March 2026).
