## Company history

Spirax Group traces its origins to 1888. Watson-Marlow, now part of the Group’s fluid-technology business, was established in 1956. [5](https://www.spiraxgroup.com/en/about-us/who-we-are)[4](https://www.spiraxgroup.com/en/about-us/our-businesses/watson-marlow-fluid-technology-solutions)

The Group expanded its specialist products and markets through acquisitions, including Aflex Hose in 2016 and steam-control business Gestra and electrical-heating company Chromalox in 2017. [25](https://app.finbar.com/go?id=P92552687)[26](https://app.finbar.com/go?id=P96366682)[27](https://app.finbar.com/go?id=P109737998) In 2024, Spirax Sarco Engineering adopted Spirax Group as its corporate identity, with its Steam Specialties business renamed Steam Thermal Solutions; Spirax Sarco continued as a trading division.
