Heatec EHI Electric Heaters

Heatec EHI Electric Heaters are commonly known as electric circulation heaters or electric process heaters. They are used in a variety of industries. EHI heaters are available in a wide range of thermal outputs, from 100 kilowatts to about 3 megawatts.
Overview
Heatec EHI Electric Heaters are commonly known as electric circulation heaters or electric process heaters. They are used mainly by companies engaged in manufacturing and processing. This type of heater is popular due to its small footprint, high thermal efficiency and low maintenance. They do not require an exhaust stack. The heaters can be used to heat thermal fluid that heats other plant equipment. Or they can be used to directly heat a liquid or gas product that flows through the heater, including chemicals, oil, water, air, nitrogen and steam.
EHI heaters are available in a wide range of thermal outputs, from 100 kilowatts to about 3 megawatts. (A kilowatt is equal to 3,412 Btu.)
Features
Heatec EHI Heater Design
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.
Heatec EHI Heater Packages
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
Heatec EHI Heater Power
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.
