Shand & Jurs Offers Solution to Reduce Emissions With Expanda-SealTM


Hillside, IL — June 16th, 2020 — Shand & Jurs, an industry leader in industrial tank equipment is offering Expanda-Seal™, a uniquely designed seal which helps reduce vapor emissions, evaporation loss and odors in many process environments.

The Expanda-Seal technology uses the internal storage tank pressure to inflate a diaphragm on the relief device creating a tighter seal the closer the pressure gets to the set point. While industry standards for pressure relieving vents can only maintain 1 SCFH at 90% of set point, Shand & Jurs’ Expanda-Seal technology flows are limited to a nearly “bubble tight” 0.5 SCFH at 95% of the set point, equating to 50% less vapor release.

Available in a full range of sizes and soft goods, this unique inflating diaphragm design also helps prevent leaks caused by worn seating surfaces requiring less maintenance saving time and money.

Expanda-Seal is ideal for refineries, tank farms, terminals, sewage treatment plants, landfills, agricultural, or the food and beverage industries. The Expanda-Seal high-performance sealing technology can be utilized on your pressure and vacuum conservation vents and emergency vents to reduce emissions and inert gas cost.
