Application
Construction For heating almost any liquid or viscous materials including acids, water, synthetic oils, lube oils as well as air, gases, steam or low melting point solids.
Constuction
The standard element consists of an 80/20nickel chrome resistance wire which is connected to terminal pins, and centered in metal tube. The tube is filled with high-quality magnesium oxide and compressed to ensure a rapid heat transfer. The terminal pins from a non-heated section of elements well as the terminal arrangement. They are insulated from the metal tube by ceramic bushes. Kilowatt rating and voltage can be varied to suit each application.
Material Sheath selection and application
COPPER
Heating of fresh water free from chlorine or other aggressive chemicals. Cooper elements may nickel plated to provide protection in certain applications. Maximum sheath temperature in water 180 C.
INCOLOY 800 / 840
A nickel chrome allow used for heating liquids where resistance to stress corrosion is required. Maximum sheath temperature 850 C
STAINLESS STEEL 304
Heating gases, where oxidization of corrosion is likely. Selection will depend on the media to be heated and the operating conditions. Maximum sheath temperature 750 C
STAINLESS STEEL 316
Heating Aggressive liquids where corrosion is likely. Selevtion will depend on the media to be heated and the operating conditions. Maximum shealth temperature 750 C
TITANIUM
Heating Aggressive liquids where other metal sheathed materials do not have the required corrosion resistance. Selection will depend on the chemical composition of the media to be heated. Maximum shealth temperature 500 C.
