Duoline Technologies recently expanded its manufacturing facility in Gilmer, Texas. The company produces Duoline from an ultra modern, ISO9001:2008 certified, 130,000 square foot plant using a manufacturing system supported by process controls and automation designed to provide repeatability and precision. “In order to accomplish our manufacturing objectives we evaluated every critical aspect of processing efficiency including options for enclosures to protect our control systems, instrumentation and electrical connections,” said Oscar Zapata, product engineering manager for Duoline Technologies. “This is especially critical in applications, such as ours, where the presence of corrosive factors constitute an ever-present and costly threat for damage to equipment as well as potentially catastrophic compromise of vital systems.” Specific to the performance of enclosures, material failure caused by corrosion or impact damage resulting in a breach of proper sealing can cause a multitude of problems ranging from catastrophic and dangerous system collapses, to production downtime, increased maintenance costs, and consequential losses in customers and revenue. While searching for an enclosure system, Douline found that defining the corroding agents and determining their concentration can be a complex but necessary process. Usually several corrosive elements are present and interactions are not always well documented. Adjacent processing operations or other intermittent activities such as industrial cleaning and the general plant environment may expose the sensitive control equipment to a variety of corrosive agents and temperatures. Each environment is unique and all possible corrosive agents should be identified for the intended application. The primary demand for reliable protective service led Duoline Technologies to ultimately select products from the Control Tower and DS (DiamondShield) series of nonmetallic enclosures produced by Stahlin Non-Metallic Enclosures. Duoline Technologies currently has a wide variety of sizes and configurations of Stahlin enclosures in service and has benefited from allowing Stahlin to use its in-house expertise in performing enclosure modifications at their production facility. The decision to use nonmetallic enclosures was guided by many factors but none more important than long service life and reliability of protective performance. Moreover, thermoset composite fiberglass enclosures provided desirable life cycle costing because of negligible maintenance and minimal recurring replacement cost due to little or no deterioration in service. Such enclosures provide

inherent safety because composite enclosures are not conductive. They are also lighter weight, reducing shipping costs and installation headaches. The Stahlin Diamondshield series was developed for design flexibility and pleasing aesthetics. Unique internal panel management capabilities provides the end user with only the features they need for their application, yet able to use every cubic inch of valuable internal enclosure space. The Stahlin Control Tower series has been designed for use in larger industrial control systems and machine tool control panels. Their industrial look and ruggedness offer a practical solution to many applications and are well suited for both indoor and outdoor environments.
Canyonwest Cases Offers New SKB Case
SKB has introduced its new 3i-1510-6 injection molded case, which is available through Canyonwest Cases. The 3i-1510-6 case measures 15 by 10.4 by 6 inches (inside dimensions) and is available in two stock configurations: foam filled (3i-15106B-C) and empty. SKB 3i series cases are available in 24 sizes, with inside dimensions ranging from 9.25 by 7 by 4 inches to 50.5 by 14.5 by 6 inches. Cases are waterproof, dustproof and crushproof. They also have an automatic purge valve and unconditional lifetime guarantee. Interior options include foam filled, adjustable dividers and custom foam. Some sizes are equipped with wheels and retractable pull-handle. SKB 3i Series Waterproof Cases meet a variety of military specifications including: MIL-C-4150J, MIL-STD648C and MIL-STD-810F. Cases are also ATA (Air Transport Association) compliant.
Re-Designed Panelboards Provide Costs Savings For Hazardous Applications
Adalet has re-designed its factory sealed panelboards, which provides real costs savings for Class I, Division 2 hazardous location applications. Modifications to the poured seal separating the cast aluminum explosion proof enclosure and the stainless steel terminal enclosure has reduced the cost of the assembly providing lower costs to the user. Designed for use in Class I, Division 2, Groups BCD and US Zone 2 areas such as refineries and petrochemical installations, the factory sealed panelboards are used to control lighting and appliance, power circuits and power distribution in applications requiring branch power distribution, over current and short circuit protection. Utilizing electrical components from Cutler Hammer, the Adalet factory sealed panelboards are pre-wired and factory sealed from the circuit breakers inside a cast aluminum explosion proof enclosure to the main distribution block and branch terminals housed in an IP66 rated, NEMA 4X stainless steel terminal enclosure. The factory seal between the breaker enclosure and terminal enclosure eliminates the need for external sealing.
