Chromalox
Electrical Heating System
Above all, the DirectConnect medium voltage electric systems slash installation and lifecycle costs. Whilst providing pollution-free operation for process heating. Chromalox sees process industries moving to medium voltage heating for applications greater than 879 kW (3 MMBtu/hr).
These systems bring a safe and reliable technical design for metal-sheathed electric process heating. For Example they use power controls for heating systems operating at medium voltages.
In conclusion, the medium voltage electric heating systems capture all the advantages of electric process heat while offering significant cost savings over low voltage, high amperage designs.

Electrical Heaters
Firstly Chromalox DirectConnect systems bring a safe and reliable technical design for metal-sheathed electric process heating and power controls for heating systems operating at medium voltages. Furthermore these patent-pending, Chromalox DirectConnect medium voltage electric heating systems capture all the advantages of electric process heat because they offer significant cost savings over low voltage, high amperage designs.
Secondly the Industrial heaters are available for use within both safe and hazardous areas with a full range of international certifications covered including ATEX, IECEx, CSA, SAA, BKI, EVPU and GOST.
MV Heating Systems
On the other hand, DirectConnect medium voltage electric heating systems find use for large heating demands. In particular in heavy industries such as power generation, oil and gas, petrochemical, and chemical.
Typical process heating applications include in-line circulation systems, heat transfer packages, and steam boilers for use as fuel gas heaters, steam superheaters, hydrocarbon vaporizers, hot oil systems, and Power-to-Heat applications.
Moreover, Chromalox invented electric heating technology when Edwin L. Wiegand, a self taught engineer, had a patent in 1915 for a resistance heating element embedded in an insulating refractory and enclosed in a metal sheath. Today they develop advanced industrial and hazardous area heating solutions for explosive atmospheres including heat tracing cables, circulation heaters, immersion heaters, fan heaters, air heaters and component heating technologies.
However a typical low voltage system will operate at about 96% efficiency.
Above all a loss of a result possibly could be from heat generation by current transmission. For example could be from: across wire, bussing, connections and instrumentation (known as I2R losses).
A multi-megawatt process heating solution operates at 4160V. Whilst using the Chromalox SCR Power Control option will maximize efficiency to nearly 99%.That 3% improvement can translate into savings of thousands of dollars per year.
Lastly, Chromalox are a world leader in the manufacturer of explosion proof and hazardous area heating solutions, including Ex e Increased Safety and Ex d Flameproof certified electrical heaters according to ATEX Directive for use in Zone 1 and Zone 2 locations – Thorne & Derrick, Experts in Equipment for Explosive Atmospheres, are stockists and suppliers of Chromalox heaters in the UK including ATEX and IECEx certified electrical heating products.
