EHS, (Electro Heat System) is a division of Applied Test Systems. EHS is a manufacturer of ceramic process heating elements of many different shapes, sizes and a variety of temperature ranges. Custom elements can be made to fit lab furnaces of other manufactures, at many times better prices than and longer lasting than the original manufacture. EHS also manufactures wide range of industrial style lab furnaces both large and small from simple split tubes to large car bottom furnaces.
2200°F (1204°C) Elements: High quality Kanthal A1 wire, consisting of an alloy of iron, chromium, and aluminum. Provides high-temperature service and long-life performance
1850°F (1010°C) Elements: 80 Ni/20 Cr wire, known for it’s reliability for decades
2200°F (1204°C) Elements: supplied with open windings or supplied embedded.
1850°F (1010°C) Elements: supplied with open windings or supplied embedded.
18 in. Standard. Other lengths available upon request
To achieve maximum element life, provide at least 1/8 in. radial clearance per inch of tube diameter when heating process tubes. For example: Provide at least 3/4 in. clearance on each side when using a 6 in. diameter process tube
Avoid rapid voltage fluctuations and temperature changes to obtain optimum element life
Elements may be connected in a series to accommodate higher voltage, however, operation at 440 volts is not recommended due to dielectric properties for the spacing and temperatures being used
Due to changes in dimensions when fired, element diameters may vary from 1/8 in. on smaller units to 3/8 in. on large ones
