DEW is one of the few companies manufacturing in Germany that produces tubular heaters made of copper. The advantages of this material are well known: it is extremely resistant to corrosion, has antibacterial effects and displays no material fatigue even over long periods of time. It is particularly well suited to use in white goods for household and industrial applications.
DEW heating element calculator
With the DEW heating element calculator you can comfortably calculate important values for the heating element you are looking for. Determine, for example, the power required to warm up a substance with a specific mass from temperature T1 to T2 in a certain time.
Select the value that you want to calculate, enter all values and click "Calculate":
Outer diameter: Ø 6.5 / 8.5 mm
Stretched length: around 300 mm – 2,200 mm, Unheated length: around 40 mm – 300 mm
Material: Cu-DHP R 290
Power: 200 W – 4,500 W (higher power ratings are available on request)
Design
On the inside, our high-density tubular heaters made of copper consist of a wound heating coil that is specially designed by our engineers. Connecting bolts are welded onto its ends in order to make the electric contact and guarantee the required unheated length. The heating coil is installed in the casing pipe with our filling machines and electrically insulated by filling the assembly with magnesium oxide.
