Safety
and Environmental Control Equipment, Manufacturing and
Engineering SolutionsFor more than 70 years ENARDO has supplied industry with the products, services and solutions that meet the challenges of environmental and safety standards. As a pioneer in the conservation equipment industry, we have evolved to become one of the largest manufacturers of pressure vacuum relief valves, gauge hatches, emergency pressure relief vents, flame arrestors and detonation flame arrestors. Our equipment is critical to the safe operation of industries around the world, including loading terminals and storage tanks, and in the chemical/petrochemical, pharmaceutical, landfill, wastewater, refining, automotive, industrial production, pulp and paper processing, and oil production markets.
ENARDO is also a recognized leader in the custom-design and testing of engineered products to meet specific applications. Our engineering design team offers a wide range of experience, expertise and engineering disciplines to provide our clients with innovative yet cost-effective solutions. ENARDO’s explosion and flow-testing laboratory facilities ensure our equipment is designed and manufactured to the highest safety standards. We are committed to the continuous improvement of our processes, craftsmanship and quality control methods to help the industries we serve operate more safely and more efficiently.

Onshore
ENARDO vent valves and hatches have set the industry standard for more than 70 years. ENARDO thief and gauge hatches with pressure/vacuum relief capability, in-line vent valves and stack vent valves prevent unwanted loss of crude light-ends in low-pressure steel and fiberglass tanks. Valve connections are slip-on compression type, eliminating the need to thread piping in the field. ENARDO's patented technology offers tight sealing and superior resistance to corrosion and sticking.
ENARDO flame arrestors are available in vent-stack and in-line configurations and offer an added measure of safety against ignition of vent gases caused by lightning or other environmental factors.
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. ENARDO pressure/vacuum models also provide high-capacity vacuum flow for emergency pump-out.
ENARDO products are available with special corrosion-resistant coatings for sour gas/crude service.
Typical Applications
Tank vents - ENARDO vent valves, flame arrestors
Tank access openings - ENARDO hatches
Tank emergency relief openings - ENARDO emergency vents
Offshore
ENARDO flame arrestors protect piping, ducts and storage tanks 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.
ENARDO pressure/vacuum 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 uses advanced composite sealing materials to provide superior cold weather performance (to -50°F) and resistance to sticky substances.
