The tubular sheathed wire elemet has long been recognised as the most versatile and widely used source of electric heat, for commercial, industrial, scientific and domestic uses.
It's reliability, strength and adaptability makes the tubular sheathed heater suitable for an unlimited number of applications and environments.
Whether you require a standard immersion heater for heating water in a tank, a heater for a large laundry on a passenger cruise liner, or a heater for a huge silo in a food processing plant, Chemical applications, Elmatic have the expertise, design and manufacturing facilities to meet your particular requirements.
Depending on the application required, sheath wire elements can be made in a number of materials including Incoloy, Stainless Steel, or Mild Steel enabling temperatures of up to 750°C ( 1400° F ) to be achieved.

• Precision Wound Resistance Wire
Nickel Chromium coiled resistor (computer designed). Precisely wound to provide exact heat requirement. Each individual spiral being thoroughly chemically washed to eliminate contamination and give a longer element life.
• Welded Connection
The connection between terminal pin and resistor is securely made by electronic welding or crimping.
• Electrical Insulation
The resistor coil is centrally located during manufacture and insulated with high purity Magnesium oxide powder. When compacted by rolling or swaging, the magnesium oxide powder provides excellent thermal conductivity and dielectric strength.
• Sheath Material
A selection of sheath material is available depending on individual customer's requirements and applications. (Please see chart for options). All heaters are fully annealed to allow forming.
• Sealing
All heaters are sealed during manufacture to protect against moisture absorption during storage. This will not however serve to protect against liquid infiltration and chemical attack. Various sealants are available for special conditions. Please consult factory for further assistance if you require any special needs.
• Insulation and Threaded Terminals
Ceramic or mica insulators ensure the electrical insulation of the terminal stud from the sheath. The standard threaded stud provides a quick and easy termination. However, a large selection of termination options is available.
