Electric Water Heater Element with Black Housing

The construction of high temperature cartridge heaters positions a nickel-chrome resistance wire precision wound around a magnesium oxide core. It is inserted into a stainless or Incoloy tube locating the resistance wire close to the sheath. The core is centrally positioned within the tube and filled with magnesium oxide powder. Nickel pins pass through the centre of the core making contact with the resistance wire at both ends. The whole is assembly is highly compacted by a swaging operation and thus ensuring excellent heat transfer to the external sheath. This allows for operating temperatures to 1600ºF and high watt densities. One end of the heater is closed with a welded metal end-disc and wire leads exit at the opposite end which is typically closed with a lava seal. A variety of wire leads and lead protection options are available. Heaters can be supplied with internal thermocouples, mounting fittings and many other options.

Product Details

1. Product Introduction

Detai offers a wide variety of process heating equipment to our customers. We manufacture boiler heaters that suit many different sizes and dimensions that customers need. If a boiler has a flanged heater that need to be replaced, Detai can replicate the model you currently have from practically any manufacturer and have your boiler system up and running in a matter of hours. Boiler heaters come in a variety of different flange sizes and lengths and materials. The two common models are rounded flanges and square flanges. The length of the boiler heater is highly correlated to the length that is available within your boiler. We now have SUS304, SUS316 and Incoloy 800 and Incoloy 840 material for you to choose. If all the major variables are known (ie. Wattage, Voltage, Length and Flange size), Detai can replicate the model you have in no time.
