Shand & Jurs (L&J Technologies) designs, manufactures and tests a complete line of Digester Gas Safety Equipment and Waste Gas Burners/Flares for municipal sewage treatment plants, landfills, dairies, food-processing and breweries. Gas safety equipment on top of digester covers including pressure/vacuum vents, flame arresters, 3-way safety selector valves along with emergency vent/manhole covers and cover position indication. We manufacture both open candlestick and enclosed flares to help reduce emissions. Our candlestick flares are offered with options for automatic ignition at the tip of the flare or at ground level. Our enclosed flares are designed to meet strict emission regulations and/or where open flames are not permitted. Proudly manufactured in USA.

Key Operational Questions

Do you have only one pressure and vacuum vent and flame arrester on cover?

• We recommend the 97190 Safety Selector Valve with Dual Units for Maintenance

How often do you clean their flame arresters?

• Should be annually. If they have old units, suggest new Shand & Jurs 94306.
• If they have Square units with trays, Spiral units are the same functionally. Lead time is 2 weeks typically.

Do your pressure and vacuum vents leak?

• • If so, we suggest to replace the seals with S&J 94020 with Expanda-Seal (Best Seal on Market)

Do you have a cold weather application?

We recommend  an All-Weather Teflon Coating and Insulation Jackets  which are available.

You wouldn’t spend any time outside without bundling up and neither should your safety devices. Fit them with Insulation Jackets from Shand & Jurs Biogas during these cold winter months to maximize your heat source and help keep condensation vapor from freezing them up which could cause damage. Our Insulation Jackets are constructed of a silicone impregnated woven glass cloth lining with a 1 inch thick 6 lb. density fiber glass insulating material. Through cover quilting pins, provide support to keep the insulation from shifting inside while providing dimensional stability ensuring uniform heat retention. Velcro cinch belts and straps with D-rings allow easy install/removal and maintenance access to tube banks when necessary without removing the entire jacket.
