Polar Tank Trailer

What Polar Tank Trailer does

Polar Tank Trailer is a privately held US tank trailer manufacturer founded in 1946, operating as a subsidiary of Engineered Transportation International (EnTrans International) alongside Heil Trailer and Jarco. The company designs and manufactures mission-specific tank trailers across six core product categories: petroleum, stainless steel, dry bulk, aluminum ring, hot products, and cryogenic trailers. Production is conducted at facilities in Holdingford, Minnesota and Athens, Tennessee, with Juarez Trailer Operations supporting manufacturing in Mexico.

The company's technology portfolio centers on proprietary hardware and software systems including TANK Ai (an intelligent fleet management system developed in partnership with Drōv Technologies, featuring an AirBoxOne central command module, sensors, cameras, TPMS, predictive wheel-end monitoring, and automatic tire inflation) and LightGuard (a proprietary exterior safety lighting system for petroleum trailers). Key named customers include Andrews Logistics, Reynolds Nationwide, Altom Transport, United Petroleum Transports, and Indian River Transport, operating across petroleum, chemical, and food-grade transport applications in North America.

Revenue is generated primarily through one-time hardware sales of custom-engineered trailers, complemented by parts, warranty services, and dealer support. The company employs a direct enterprise field sales model using six Regional Sales Managers covering the US, Canada, Mexico, Latin America, and the Caribbean, supported by an established dealer network for parts, sales, and service across North America. Pricing is quote-based and not publicly disclosed, reflecting the custom-engineered nature of each trailer order.

Direct peers

• Heil Trailer International: Sister brand under EnTrans International, also manufacturing tank and bulk trailers (dumps, refuse, oilfield) for petroleum, chemical, and construction transport. Most directly comparable product portfolio and customer base, with shared engineering, manufacturing, and distribution infrastructure.
• Mac Trailer: Family-owned aluminum trailer manufacturer including tank, dump, and flatbed trailers. Comparable in mission-specific engineering approach and direct-to-fleet sales motion, competing across multiple of Polar's product categories.
• LBT Inc. Manufacturer of vacuum, tanker, and specialty trailers based in Louisiana. Competes directly with Polar in petroleum and chemical tank trailer segments for North American fleet customers, with similar DOT-code specialization.
• Tremcar Inc. Canadian-based tank trailer manufacturer specializing in stainless steel, aluminum, and specialized trailers for food-grade, chemical, and petroleum transport. Direct comparable in product mix and North American customer base, particularly overlapping in the Canadian market where Polar also competes.
• Jarco (EnTrans brand): Sister brand under EnTrans International manufacturing tank trailers for industrial liquid and bulk transport. Most directly comparable manufacturing operations and customer segments within the EnTrans portfolio.
• Beall Corporation: Manufacturer of tank trailers, truck bodies, and related equipment based in Portland, Oregon. Direct competitor in the petroleum and chemical tank trailer market with overlapping West Coast fleet customer base.

Broad incumbents

• Utility Trailer Manufacturing Company: One of the largest North American trailer manufacturers with broad product portfolio including refrigerated and dry freight. Competes for similar fleet customers and shares multi-product purchasing dynamics, though less focused on liquid/bulk tank trailers.
• Great Dane Trailers: Long-established trailer manufacturer offering dry van, refrigerated, and specialty trailers. While not a focused tank trailer player, it competes for similar fleet customers and benefits from scale advantages in manufacturing and dealer networks across North America.
• Wabash National Corporation: Public, larger-scale trailer OEM with a diversified portfolio including dry van, refrigerated, platform, and tank trailers through its subsidiary Walker Tank. Comparable in tank trailer manufacturing but with much broader transportation equipment exposure and substantially greater R&D and telematics investment capacity.

Emerging players

• Fruehauf (Wabash brand): Historic tank trailer brand now part of the broader Wabash/Fruehauf Group, serving European and select international markets. Comparable tank trailer product category but primarily regional rather than North American focus.
