Product Description

         Factory Wholesale Industrial Immersion Water Heater Tubular Heating Element Heater 

1. Tubular Heater Introduction

Tubular Heater are custom designed in a various shapes to as client's requirements for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases.

Tubular heaters are produced using Incoloy, stainless steel or Copper sheath materials and also there is huge variety of selection of termination styles available. Insulation of Magnesium offers greater heat transfer.

Tubular heaters can be used in any application. Straight tubular can be inserted in machined groves for conductive heat transfer and formed Tubular provides consistent heat in any type of special application.
