Finned Electric Heating Tube

Finned electric heating tube is a kind of heating element that converts electrical energy into heat energy to heat the material to be heated. Finned tubular electric heating element is a metal heat sink wrapped around the surface of ordinary elements. Compared with ordinary heating tubes, it has a larger contact area and higher efficiency .exclusive construction. High-quality, coiled nickel-chrome resistor wire is uniformly spaced over the width and length of the finned strip element, then embedded in high-grade refractory material which both insulates the wire and transfers heat rapidly. The refractory is then compressed to rock hardness and maximum density under tremendous hydraulic pressure to improve heat transfer from coil to sheath. Elements are oven baked at high temperature to semi-vitrify and https://kidsparadise.com.ua mature the refractory. Sheath material is either rust-resisting iron or chrome steel. Fins of aluminized steel are provided to improve heat transfer to the air. Elements are individually replaceable.
