Thermocouple & RTD Cables

Mineral insulated cables are ideally suited to temperature measurement applications at up to 1150°C because they physically isolate wires from the surrounding atmosphere, shield from sources of electrical interference, protect from damage due to shock or impact, allow bending of the final assembly due to their flexibility, have low thermal mass, giving fast response times, and minimise contamination effects at elevated temperatures through the use of high quality sheath and insulation materials.

All of this is achieved in a low cost product, with certification relating to calibration and traceability supplied as standard.

M.I. Heating Cables

Mineral insulated heating cables are manufactured with a NiCr8020 heating element and a 321 stainless steel or Inconel sheath. Other sheath materials are available for specialist applications, and the cables can be used in applications up to temperatures of 1,000°C, depending upon the sheath selected. Suitable cold end cables are also available in a selection of sizes to suit the individual application. These heating cables are suitable for transferring large thermal volumes, since a high per-metre load is possible under appropriate conditions.

We can supply you with the raw cables for you to manufacture your own heating elements, or we can supply finished elements to your specification.

Cartridge Heaters

Marathon Heater''s Hotrod swaged cartridge heaters are the industry standard.  Designed and manufactured for temperatures up to 870°C (1600°F), and available in metric or imperial sizes, there are thousands of stock models or custom-designed heaters for your specific application.

Band Heaters

Band heaters are available in both Ceramic and Mica types.  Ceramic band heaters offer more flexibility and a higher operating temperature than Mica heaters, but are not as compact.

Ceramic Heaters are available in diameters from 75mm (3”) to 380mm (15”), whilst Mica Heaters can be supplied in diameters from 19mm (3/4”) to 1500mm (60”).  A wide range of sizes and wattages are available from stock, or we can supply to your own specification.

 

Starflex Band Heaters

The Marathon Starflex band heater is an extruded aluminum segmented band employing rugged refractory insulated tubular heating elements. The low expansion clamping band provides snug barrel fit and and assures excellent heat transfer through the entire operating temperature range up to maximum heater temperatures of 315°C (600°F). This band heater enjoys wide acceptance because of extremely long and reliable life characteristics. Operators of plastic extruders and injection molders experience minimum down-time with the Starflex band. It is also one of the most efficient band heaters available.

Some applications require both heating and cooling. With the advent of exothermic materials and heat generated by screw rotation, the proven Marathon Starflex band heater was adapted to provide both heating and cooling functions. Cooling tubes are placed in proximity to the heating elements to produce the Marathon Starflex Heat/Cool band. Due to its low mass, it can be cooled relatively quickly.

Silicone Rubber Heaters

Silicone Rubber Heaters offer a very high watt density while maintaining flexibility. Good for heating drums, de-icing vending machines, ATMs, aircraft, cars, and maintaining a comfortable temperature in medical equipment, such as CAT scanners.

Marathon Heater flexible heaters provide outstanding performance in applications up to 230°C (450°F).  Design versatility permits special heat profiles,complex shapes and installation on a variety of surfaces.  They are not affected by vibration, flexing, or repeated mechanical shock.  Silicone rubber has a high dielectric strength, is non-toxic, and is flame-retardant.

Kamlrok Refractory Disc Heaters

These unique heaters are constructed or a rust-resisting iron sheath (400°C [750°F] Max Temp.) with optional chrome steel sheaths (510°C [950° F] Max Temp.) available. They are precision pieces of equipment proven to be suitable for continuous duty applications. Heater reliability is assured by high quality nickel-chromium resistance wire, which is embedded in a special ceramic formula developed for long life with excellent heat conductivity. This refractory insulation is compressed and then cured in high temperature ovens to ensure maximum quality.

Isoheat

Specialist heating applications are Isoheat's forté.  Heating mantles and crucible heaters for laboratory use, pre-heating jackets for Formula 1 racing car tyres, flange heaters, heating panels, heaters for high vacuum applications, heated hoses – these are just some of the products that Isoheat can make to your specification.  High-tech production equipment, such as laser welding machines for producing rugged and reliable MI heating cables is standard.  Please contact us for further details.
