struction since the design pressure has to be typically over 100 psig, and sometimes over 150 psig, which is far above the normal, required operating pressure conditions of the equipment. As a consequence, containment is only economically viable for processes that are small volumes and / or high added value, such as some pharmaceutical manufacturing and for industries handling toxic materials that cannot be released to the environ- ment. In this type of system, the isolation devices play a critical role in preventing damage to connected equipment and piping. For this, fast activating knife gate or pinch valve device can be used, as well as chemical isolation systems. With containment systems, however, isolation equipment must also be able to withstand greater pressures, up to 150 psig, unlike similar equipment required with vents or suppression devices that must survive only 3-10 psig. 1 Pigeon = Regardless of the type and combination of equipment installed, the appropriate solution for each applica- 25 lbs of unhealthy, corrosive and ugly bird droppings per year Protect People & Property • Surface Sanitizers & Deodorizers • Stainless Steel Bird Exclusion Spikes • Structural Bird Exclusion Netting • Bird Fogging & Hazing Equipment 67 Years 1950 - 2017 Free Bird Control Catalog or 888.624.1189 Nixalite® of America Inc 1025 16th Ave, E.
