Landfill

ENARDO flame arrestors protect piping and ducts against accidental ignition of flammable vapors. Many ENARDO flame arrestors are Factory Mutual (FM) and ATEX certified to ensure the highest level of safety*. Our detonation arrestors feature a patented flame cell design with larger crimp openings than competing products, resulting in lower pressure drop, less plugging and easier cleaning.

Typical Applications

• Flare/combustor gas inlet
• Gathering lines
• Vapor recovery manifolds
• Vent stacks

ENARDO pressure/vaccum relief valves limit unwanted vapor emissions by maintaining pressure in storage tanks while allowing for thermal inbreathing and outbreathing, as well as normal filling and draining operations. ENARDO designs its pressure/vacuum relief valves with advanced composite materials to provide enhanced sealing characteristics, superior cold weather performance (to -50°F) and resistance to sticky substances.

ENARDO emergency vents supply storage tanks with the extra relief capacity required by OSHA (29CFR 1910.106), API Standard 2000 and NFPA 30 in the event of an external fire or overpressure caused by a process upset. ENARDO pressure/vacuum models also provide high-capacity vacuum flow for emergency pump-out.

ENARDO hatches provide secure tank access, most with pressure/vacuum venting capability. Our full product range includes spring-loaded, dead weight loaded and lock down types.

Typical Applications

All ENARDO products are designed and manufactured in facilities certified under ISO 9001.
