Heatec EHI Electric Heaters

We take special care to design the heater for optimum watt density and flow through its heating chamber. The heating elements have large heat transfer surface areas, which reduce heat flux rates. The lower the better. And ours are lower than those commonly used by others. We size the chamber and heating elements to achieve an ideal fluid velocity of 5 to 13 feet per second. The heating chamber is built to ASME code. The types of metal used in construction of the heater are critical. They must be fully compatible with the materials being heated. We carefully select all parts that come into contact with the material being heated. Wetted parts may be carbon steel, stainless, Incoloy, Inconel, or another material, as necessary.

The heaters can be customized to meet your specific needs. We offer them as skid mounted packages with a variety of options:

• SCR control panel
• Expansion tank
• Main pump
• Backup pump
• Strainer
• Side stream filter
• Valves
• Cooler

EHI heaters can be configured to operate on electrical power provided by electrical utilities throughout the world. Our standard configuration of electrical power is for 3-phase, 480 volt, 60 hertz alternating current. Some users may need to increase available demand from their utility, depending on the wattage of their heater. We offer a variety of control panels for use on heaters that operate in locations classified as hazardous in NFPA 87 code.
