Reduce Emissions and Odors with Shand & Jurs’ Expanda-Seal


With reducing emissions having an increased importance, Shand & Jurs offers Expanda-Seal™ technology. Expanda-Seal™ is a patented seal on pressure relief devices that will significantly reduce emissions and odors in every process environment imaginable while also saving valuable product. 

While industry standards have a tested leakage rate of 1 SCFH at 90% of set point, Shand & Jurs’ Expanda-Seal™ pallets are tested to 0.5 SCFH or less at 95% of the set point, equating to 100% less vapor release. This uniquely designed seal uses internal vessel pressure to inflate the pallet gasket, which creates a tighter seal the closer the pressure gets to the set point.

Expanda-Seal™ is exclusive to Shand & Jurs and can be applied to virtually any of the Shand & Jurs’ pressure devices including conservation vents, pressure relief vents, emergency vents, and the combination conservation vent and flame arresters.
