The Rootselaar Group history

Tankbouw Rootselaar was established by Mr T. van Rootselaar in 1957. After he returned from the Australian oil refineries, he decided to venture into the production of propane tanks. Over the years, he increased the size of the vessels, eventually manufacturing tank trailers.

Pressure vessels, cryogenics and engineering

In 1988, when his children entered the business, they expanded their business to include pressure vessels for multiple gases. With the acquisition of Cryovat in 1996, the Van Rootselaar family further diversified their business and founded Rootselaar Group. In 2021, the third generation Van Rootselaars took office, ready to continue consolidation and growth.

Through acquisitions and joint ventures, Rootselaar Group has grown to 6 companies hailing from 3 continents. Of these companies, Tankbouw Rootselaar works most closely with cryogenics expert Cryovat International and engineering firm Hadetec.

Exchange of relevant engineering expertise

Being part of Rootselaar Group enables us to draw from added expertise elsewhere in the Group. As a result, we offer a wide range of vessel-related products and services, from comprehensive advice and tailored designs to additional piping and entire systems.
