LESER tests safety valves for Korean hydrogen installations
Korea, one of the leading nations in hydrogen technology, is driving the development of hydrogen applications around the world. To meet customer requests and testing requirements, LESER invested in the construction of a test bench capable of testing safety valves for hydrogen applications at realistic operating temperatures.
In this market, LESER has positioned itself as a leading supplier of safety valves designed for hydrogen. Projects in Incheon, Changwan and Ulsan have been successfully equipped with LESER Safety Valves.
International cooperation as the basis for success
A wide range of international technology suppliers, plant engineering companies and original equipment manufacturers for various components were involved in various projects.
Winning orders for these projects is a process that exemplifies the importance of LESER’s international cooperation and teamwork in global sales. LESER France, LESER India and partners in the Netherlands collaborated to win the individual orders and execute them to the customers’ satisfaction. This international interlinking of knowledge and expertise is key to LESER’s success across national borders.
Building a test bench at the Institute for Air and Refrigeration Technology in Dresden
The basic purpose of the test set-up was to test the safety valves at realistic operating temperatures. The valves were tested using cryogenic, liquefied helium. A particular challenge was verifying temperatures as low as –223°C / 50 K at the safety valve inlet using a temperature sensor. The valve opening and closing action in the presence of liquefied hydrogen had to be simulated as realistically as possible to ensure the tightness of the valves after opening.
