High-pressure technology specialist Hiperbaric was looking for Ex rated sealing solutions when designing their new modular and mobile green hydrogen compressors. They chose two types of seals from Roxtec.
“Roxtec is our partner for sealing multi-cable and pneumatic tube penetrations inside the hydrogen compressors,” says Luis Ángel Ramos, Electrical Engineering Chief of Hiperbaric. “We also get valuable technical help. Roxtec experts have checked the installed system onsite to verify everything is correct.”
Avoiding the risk of explosion
Hiperbaric is an international provider of high-pressure processing equipment based in Burgos, Spain. Among the cutting-edge technologies leaving their factory are containerized hydrogen compressors for storage and supply of refueling stations. Inside each container, there is an Ex zone 2 classified area that must be separated from the next compartment. Therefore, they need tight and Ex rated cable and pipe transits to make sure the explosive hydrogen gas is safely kept where it should be.
Flexibility enables modularity
Hiperbaric selected Roxtec for several reasons. Roxtec is recognized worldwide for its modular-based sealing solutions, and the technical solutions were adequate, flexible, and enabled scalability. In addition, the seals require minimum maintenance while offering built-in spare capacity.
“The Roxtec S Ex solution for multiple cables of different sizes is the best way for connecting two separated areas,” says Luis Ángel Ramos. “The Roxtec C RS T Ex seals for single cables have also been an easy and efficient solution to implement as a standard for individual cable connections.”
