GAS TECHNOLOGY Thermador’s Star Burner is designed to evenly heat cooking vessels. the igniter offers good corrosion resistance, is strong, and lights the gas without the associated noise of a direct spark ignition system, says Stephen Bruce, product manager for Fisher & Paykel. According to the company, the Aero burners on the CookSurface offer precise linear flame control accomplished by an integrated fan in the burner system. The variable speed fan delivers an optimized mix of oxygen and gas to the burner, which helps to control both the low simmer and high flame settings. MP Series, Programmable process temperature controls for paint curing. The second feature that sets this CookSurface apart from other technologies is the rotary lift system that raises and lowers the burner and the hidden pan supports for each of the three burners. When it reaches full height, the pins lock into place and will not retract while a flame is present or if the pan supports or burner cap are hot enough to potentially damage the unit. Fisher & Paykel uses a temperature sensor to control this safety feature. Because the burner system rises and retracts, the designers needed to ensure that none of the gas lines would crimp. The solution, they say, was to not have the gas lines move at all. The base of the burner, to which the gas lines are attached, stays in place. Instead the burner head telescopes up for cooking. While other technologies may not be as unusual in scope as the CookSurface, they each work to satisfy the most important aspect of a cooktop — providing a full range of heat from a low simmer to very high heat. The easiest way to accomplish this is to have dedicated burners, but that limits the consumer’s ability to concurrently cook multiple items that might require the same heat level. George Simadiris, vice president of engineering for Dacor, Huntington Beach, Calif. says that his company’s new Renaissance cooktops have a wide range of heat settings, operating at the CV Series, Redundant combination controls for RV furnaces and water heaters. Our technological developments are not common knowledge but we know they’re appreciated. www.maxitrol.com Fagor’s new 28 in. gas cooktop features 5 burners, including one Triple Crown burner, which has three concentric rings of flame for even heat distribution. Each burner has an individual spark generator. November 2008 1/11/08 10:19:22 AM 26 applianceDESIGN AD02084Max.indd 1 www.applianceDESIGN.com http://www.maxitrol.com http://www.appliancedesign.com
