Athens, TN – (September 9, 2026) – Polar Tank Trailer, a subsidiary of Engineered Transportation International (EnTrans), is marking its 80th anniversary in 2026. The company will commemorate this significant milestone with a special celebration at its Minnesota Trailer Operations in October.
Polar’s roots trace back to 1946, when brothers Vince, Roy and Frank Warzecha founded Opole Blacksmith Shop in Opole, Minnesota. Skilled craftsmen and welders, they built a reputation for producing high-quality stainless steel tanks used in the bulk milk distribution industry.
Today, Polar is a trusted name in tank trailers, specializing in chemical, food, petroleum and dry bulk trailers designed for durability, safety and exceptional long-term value. The company sets itself apart in the industry with mission-specific engineering, designing trailers with precise tolerances, innovative features and advanced technologies that maximize payloads and enhance operational efficiency. An extensive dealer network provides the support customers need throughout the life of their equipment.
“Over the last 80 years, Polar has built a legacy of quality, innovation and customer satisfaction,” said Randy Arlt, Senior Vice President of Sales for EnTrans and former President of Polar Corp. “Our dedicated team has played a critical role in helping us achieve this milestone, and we are immensely grateful to them and to our loyal customers and partners.”
Polar will showcase its latest innovations at the National Tank Truck Carriers (NTTC) Tank Truck Week in Oklahoma City, Oklahoma, September 27-30, at booth #801. A new dry bulk trailer—re-engineered from an existing crude oil trailer and specially designed to be lightweight and maximize payload capacity—will be on display.
