Heating for process application
HOmatic pinch valves: Ideal closing and measuring of bulk goods, liquids and gases

electing the correct heating for a process application used to mean only one thing: shell and tube or plate heat exchangers. But for more than 30 years now specialist
companies have been developing direct electric heating solutions. Initially viewed with suspicion, especially in hazardous areas, they
have now become commonplace and are available with hazardous area certification to suit all markets.
Power also used to be a consideration with heaters around 100Kw being considered large, but today we are seeing increasing applications for multi-megawatt systems especially in gas plants. Electric heaters are therefore a viable source of heat for most
applications in the hydrocarbon sector and use the energy in a much more efficient manner with little or no transmission loss between the power source and the heater unlike heat exchangers which need high pressure high temperature piping to be run in both directions. Electric heater manufactures use a variety of tools to design heaters to accurately match the flow conditions and process requirements to produce compact designs and generally they supply an integrated control system as part of the package.
The design criteria are best left to the manufacturer as they will invariably produce the most cost effective design. Chromalox manufactures the world’s largest and broadest line
of electric heat and control products, including heating components, immersion heaters, circulation systems, heat transfer systems, boilers, industrial and comfort air heating, heat trace cables, sensors and precision electronic controls. It provides heating solutions for diverse process industries by custom designing equipment to specifically fit customers’ needs.
With vertically integrated manufacturing and full design and
engineering capabilities, it can implement virtually any electric process heat and control application. This approach helps save time and money before start-up,
maximising efficiency, and reducing downtime after installation, and providing exceptional field service and on-going technical support throughout the lifecycle of the product.
Key industries served by Chromalox include: petrochemicals; power generation; pharmaceuticals; chemicals; oil and gas; food processing. ■
