About GESTRA
GESTRA GmbH, based in Bremen, develops and manufactures solutions for steam, condensate and industrial liquids. The product portfolio includes steam traps, control and actuator valves for demanding operating conditions, shut-off and check valves, strainers, as well as systems and complete solutions for the boiler house, including electronic boiler controls of the SPECTORconnect and SPECTORmodul series. All products and customised turnkey solutions are developed and manufactured at the company's own production site in Germany, among other things for high-pressure steam and water applications with valves of the ZK series (DN 25 to DN 300). In addition to manufacturing, the company offers services such as plant and system audits, steam trap surveys, wireless monitoring with ecoBolt sensors, maintenance support and project engineering support. Customer industries include boiler manufacturers, chemicals, general manufacturing, power generation, as well as oil, gas and petrochemicals. Founded in 1902, the company has been part of Spirax Sarco Engineering PLC since 2017.
