Rupture disc out of this world.

UKB® LS

for low burst pressure + high vacuum.

REMBE® UKB® LS
Reliable. German. Safety.
The UKB® LS comprises a customisable housing, a reverse acting rupture disc and a three-section knife. This design provides the lowest possible burst pressures while at the same time offering good vacuum resistance even up to high vacuum conditions. The rupture disc and housing are micro-welded and all elements are made of metal. This ensures maximum leak-tightness. Leakage rates of up to 10-10 are possible.
With a wide array of available connections, we supply the ideal pressure relief unit for every application – even for ultra-clean processes. Despite its individuality, a number of “standard” sizes have become established for UKB LS over the last few decades. These are for installation between industry standard flanges.

Advantages
  • Maximum leak-tightness: also for helium.
  • Also suitable for high vacuum applications.
Mechanism
When the defined burst pressure is reached, the rupture disc is pressed against the knife and opens.

Ferdi Hillebrand and Sebastian Tomaszewski, the Compact Rupture Disc Team
"We build all the UKB® LS rupture discs, and nearly all of them look different. They never have the same shape or connection, which makes our work exciting. We work together very closely, so it’s a bit like family, and we often meet after hours."
