Chromalox Introduces DirectConnect as Part of Its Extended Voltage Technology Platform

New 4160-volt Chromalox DirectConnect systems provide significant installation savings and lower the cost of ownership for multi-megawatt electric process heating systems

PITTSBURGH -- Chromalox, a leader in advanced thermal technologies, today announced the availability of DirectConnect medium voltage electric heating systems (patents pending). These systems especially suit multi-megawatt applications in such heavy industries as power generation, oil and gas, petrochemical, and chemical. Chromalox supplies up to 7200-volt DirectConnect systems for virtually any process application, such as circulation systems, heat transfer packages, and steam boilers.

According to Mark Wheeler, Chromalox Global Director of Systems & Service, systems employing Chromalox DirectConnect become cost effective for heating applications in the one megawatt range and above. "At these power levels, our studies indicate significant savings for medium voltage systems when accounting for installation as well as product cost," says Wheeler. "With our DirectConnect medium voltage system, the step-down transformer cost can be reduced or even eliminated. The decreased amperage requires fewer circuits, smaller wire sizes, and significantly less labor."

Mr. Wheeler adds that operating and maintenance costs also improve. Chromalox DirectConnect systems have less I(2)R energy loss, resulting in higher operating efficiencies," says Wheeler. "In general, electric process heat systems--having no moving parts and a clean, robust design--enjoy low maintenance costs," he says. "Additionally, all Chromalox DirectConnect systems incorporate replaceable medium voltage heating elements. Being able to quickly replace a single heating element can simplify maintenance and avoid costly process downtimes."

Aside from designing and building DirectConnect heating elements, Chromalox also manufactures all the associated power control panels that support the proprietary system. This in-house capability allows Chromalox to offer a full selection of controls that best meets customer needs. Power control selections such as contactor, full-SCR, or SCR-trim load provide an optimal balance between cost and performance.
