The global challenges posed by the climate crisis, Covid-19 and the drop in oil prices are spurring innovation. Pharmaceutical companies are striving to produce vaccines and new medicines, while natural refrigerants and cold recovery through LNG are becoming increasingly energy-efficient solutions.

Ningdong, situated 900 kilometers west of Beijing, is poised to emerge as a key hub for petrochemical refining of mineral coal in Asia. With an estimated 27 billion tons of mineral coal deposit, the facility aims to boost industrial capacity, producing 20 million tons of finished products annually within the next decade.

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. In this special issue, we introduce our work in LNG applications.

Versatile and easy to transport, LNG is an increasingly popular fuel both in marine and onshore applications. Besides energy, LNG is used as a raw material in chemical processes, and its full potential is being unleashed through heat transfer and cold recovery.

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.

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.

Read the case about Vahterus Ring, a game-changer in ski tunnel technology located in Uusikaupunki, Finland. Unveiling a pioneering approach to energy optimization, this 1 km tunnel utilizes natural refrigeration powered by carbon dioxide, with independently adjustable units ensuring precise temperature management. Its innovative design not only guarantees a reliable ski season but also showcases a sustainable model by storing and reusing snow during the off-season, setting a new standard for environmentally conscious engineering in winter sports facilities.
