First in quality Quality is an integral part of the partnership with customers, because when the quality is consis tently maintained, customers gain a competitive edge: trememdous savings in products costs, warehousing, field service, warranties and many other areas. Even for the simplest element, Chromalox has instituted eight raw material and manufacturing process quality checkpoints for tubing, eleven for resistance wire and terminal pins and nine for the purity and uniformity of refractory insulation mate rial. A total of 105 checkpoints are involved in the manufacture of one simple spiral electric rangetop element, including a final operation test at full tem perature. Similar tests are performed on all Chromalox products. When specified, products can be supplied to meet stringent third party approvals and specifications: • National Electric Codes (NEC) • Underwriters' Laboratories, Inc. (UL) • Factory Mutual (FM) • American Society of Mechanical Engineers (ASME) • Canadian Standards Administration (CSA) • Mine Safety and Health Administration (MSHA) • British Approval Services for Electrical Equip ment in Flammable Atmospheres (BASEEFA) • Military Specifications Chromalox has learned through many years of experience that quality is consistently built in to every product. Other suppliers often rely exclu sively on final inspection to catch defective items. Chromalox is committed to building in quality to reach the ultimate goal of zero defects. This commitment to quality is demonstrated by the significant investment in automation and manufac turing processes. This highly automated production Top: X-rays provide verification of Range surface element testing is equipment developed by Chromalox assures con internal construction, dielectric an expensive operation, but it sistency among millions of identical elements. clearance and design integrity to assures that each element will assure proper performance in the perform to specification.

First in customer service No company has a stronger commitment to cus tomer service than Chromalox. It extends from the product line engineers who develop new products and systems to the more than 200 field application engineers and service people who provide special ized expertise not available from any other source. Largest available stock. Because Chromalox maintains the world's largest warehouse stock of electric heating products, the company responds quickly and efficiently to customer needs. Benefits from highly automated and responsive manufactur ing techniques, skilled engineering methods and shorter delivery are passed on to customers in the form of superior service capability. Local stocks are also strategically situated near your point of need. Filling your immediate need. A national com puter network, known as CHROMALINK, increases the speed and accuracy of order filling, provides accurate inventory status and permits instant order status confirmation. It connects corporate head quarters to sales offices, warehouses, and manufacturing locations. In fact, almost all ship ments of over 5000 standard stock items are shipped the same day that the order is received. Automated design. If custom designed products or systems are required, Chromalox engineers, utilizing sophisticated computer techniques, react quickly to provide special design features that will satisfy the customer's request. Local application engineering. Over 200 Chro malox field application engineers are available to assist engineering personnel at any customer loca tion.

The flat top and bottom sur faces may be flush mounted or sand wiched between two heat-conducting metal parts. Straight heaters can be mounted on surfaces curved to 6" in side radius or larger. The heater may be field bent to minimum 3" inside radius. Standard strip heater clamps and clamping bands may be used for mounting. 34

Type CTB Applications • Immersion for deep fat fryers, de- greasers, plating tanks, humidifiers, lube & fuel oil heaters, hydraulic oil heaters, water heaters • Clamp-on for griddles, tanks, platens, dies, molds, heat sealing • Process air duct heaters, dirty gas stream, high temperature gas. Features New configuration. The Chromalox Thin Blade is a new configuration in heater element design. It is adaptable to a wide range of appli cations now served by tubular elements, and offers the following unique ad vantages: More efficient heat transfer. The larger sheath area of the Thin Blade conveys heat more rapidly to the gas, liquid or solid to be heated. Heat-up is faster at lower sheath temperatures. Dimensions (Ins.)

A/31 Component heaters/cartridge Chromalox Cartridge heater selection guide High watt density Type CIR Advanced internal construction plus Type F life-insuring flexible leads. The challenge to Chromalox engineers was to design a cartridge heater that would out-perform any brand cartridge heater — including Chromalox — under any given set of conditions, and to as sure that the Customer receives and continues to receive the most heater performance and life possible for his in vestment. Type CIR is that kind of cartridge heat er. It includes several significant ad vances in cartridge heater technology. Its high performing characteristics have been proved out not only in the labora tory but also on Customers' equipment on specially selected problem applica tions, at 1500°F and higher operating temperatures.
