Stahlin Non-Metallic Enclosures Solar Control Application Case Study

“Not all enclosures are created equal. Success in any application demands that the proper enclosure product be specified to meet the individual environmental factors impacting the reliability of proper protection for important controls and electrical systems.” – Jim Brant President, City Water LLC

City Water LLC provides municipalities turnkey wastewater treatment plant solutions capable of effectively accommodating between 500 to 10,000 gallons. The evolution of this system featured the need to overcome a significant challenge specific to the reliable protection of critical controls.

Many of City Water’s wastewater treatment systems are in demanding environments subject to high humidity, corrosive salt water and strong UV degradation. After two-to-three years of service in such applications they began to notice that the integrity of their controls was being threatened by failure of the electrical enclosures used to house and supposedly protect them. At that time, they used stainless steel enclosures that were not suitable for long-term reliability within this particular combination of environmental pressures. Part of this problem originates with the fact that although tensile strength is high with metal enclosures, flexural strength (the material’s ability to withstand denting) is relatively low. Once metal has gone beyond its elastic limit it has created a potential leak path that could compromise an enclosure’s seal integrity

Initially they thought that simply by switching to non-metallic enclosures the problem would be solved. However, even with some non-metallics the harmful effects of UV rays were still evident through “blooming” of the polymeric substrate. They were also not satisfied with design elements that seemed to inhibit the amount of available space within such enclosures — and the ease with which controls could be mounted inside…>>Read More
