Vahterus is currently undertaking an interesting series of tests. Previously, we have focused on high temperatures, phase-changing phenomena and fluid hydraulics. This time, Vahterus test lab personnel are conducting a larger series of cryogenic tests.

Founded by Mauri and Sinikka Kontu, Vahterus is proud to be a family business. The company also employs three members of the Ahola family.

Vahterus’ LNG journey began in 2005. Through extensive R&D work and with over 300 heat exchangers delivered to cryogenic LNG applications, we’re now leaders in the field.

Low temperatures and widely varying temperature differences in cryogenic applications can cause high stresses to the constructions. Practical testing of constructions is often complicated and time consuming, which is why modelling and simulation tools have become an important part of the development process.
