cartridge heaters are cylindrical electrical heating elements. Mostly used for heating up solids such as injection presses heating plates or various tools, they can also be used for heating up water of gases under certain conditions. Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc they are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries Various cartridge heater technologies are available. The choice of technology will depend on technical specifications required and the application. Unless you know exactly which product you are looking for, we will recommend you the best solution for your needs.

Tubular heaters are custom designed in a various shapes to address 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.

Thermocouples are manufactured in many different configurations for multitude of applications. Diameters, lengths, sheath material, lead lengths and sensor material are just a few of the variables that go into determining the style of thermocouple when manufactured. The main determining factors of what type thermocouple needs to be used in a application is temperature, environment, response time and accuracy. The junction of the thermocouple can be grounded, ungrounded or exposed. The thermocouple junction may be of many different styles, from tube type to a washer configuration. The lead length may vary depending on the distance of the temperature controller from the thermocouple sensor. The metal that the sensor is constructed of determines the type of thermocouple manufactured.

Electrical Resistance Wires
is used for electrical heating element up to 1200 degree centigrade. These are manufactured using qualitative raw materials like iron, chromium, aluminum and ferric alloy. Further, our range finds application in domestic appliances, heating elements operating in air, quartz tubes and electrical immersion heaters. Our wires are available in the form of ribbon and customers can choose resistivity in ohms/cm at 20 degree centigrade。

  Nickel chromium. Nickel chromium alloy with iron resistance electrothermal high resistivity, surface body sexual well. At high temperature and high intensity, and a good performance and processing may welding nature widely used metallurgical, electrical, mechanical components and electrical manufacturing industries for doing heat resistance material

We have has a wide range of Infra-Red heaters in ceramic and Quartz Types.Available Ex-stock (With thermocouple & without thermocouple from 100 watts to 1000 watts) for Applications such as:

• Plastifying foils & sheets thermoforming process.
• Manufacturing shrink (skin) wrappings.
• Drying Ceramic Tiles / Washed Glass / Tempering Glass.
• Drying raw & Printed Paper.
• Drying glued wood OR Furniture parts.
• Heating chocolate coatings / keeping food warm.

Heating processed cheese, etc.

Band & nozzle heaters are ideal for every type of plastics processing equipment. These heaters are manufactured from high quality mica or micanite sheet and have Nickel Chrome resistance. It is covered by metal sheathing & can be rolled to the required shape. The use of mica is cost effective, allows the weight of the heater to be kept to a minimum and accelerating heat transfer through the sheath of the heater & into & the object requiring heat. Band heaters operate efficiently when the sheath temperatures are kept below 250 degree centigrade. If this temperature is maintained, the life of the band heaters gets long.

Cast-in Heaters are made of formed tubular elements cast into Aluminium, C.I. or Bronze. Cast heaters can be made in a variety of shapes and sizes to meet specific applications. Cast heaters can also be manufactured with cooling arrangements to minimise temperature overshoot. Cooling can be air cooled or water cooled. Our company is better known for manufacturing quality cast heaters, which are a source of durable heat. The available cast heaters are unique in various features including great versatility in mounting. Further, our range of cast heaters are contamination and corrosion resistant and show very good performance at high temperatures and pressures in harsh environments. Also, these heaters have trouble free services for years.

Coil heaters utilize a proprietary internal micro-coil design that delivers high watt densities to concentrated areas such as plastics injection molding nozzles, small heat transfer pipes, hot knives, and concentrated chambers.
Coil heaters can be tightly wound or the coil can be distributed to provide a uniform heat pattern over a wide area. Whether you require a standard size for your plastic machinery or a custom configuration for wafer processing, Durex engineering can specify the design you require.

We are specializing in high temperature wire,such as silicone rubber wire/cable, teflon wire,glassfiber silicone insulated wire, VDE silicone rubber-non knitting high temperature resistant wire, VDE silicone rubber -insulated and high temperature resistant wire with glass fiber braided, UL high temperature resistant wire, high voltage resistant fixing wire, silicone rubber flexible cable.

silicone rubber heater is an excellent dielectric material and protects the internal element from physical and environmental damage. 
Silicone rubber heaters can be constructed using a resistance wire or foil as the element.  Foil is chemically etched to create the element pattern.  This chemical etching allows designers the flexibility to distribute wattage and create heat patterns within a single heater.

Silicone rubber heaters can be provided with integrated temperature sensors, thermostats, and a variety of mounting or attachment options.  Consult Heatron and collaborate with our engineers to create the right heater solution for your application.

Flexible Ceramic Pad heater flexible ceramic pad heaters are designed for most preheat and post heat treatment (stress relieving) requirements on weld joined materials. They can be used to construct a simple, inexpensive furnace when combined with the proper insulation as well as in many other applications where a flexible heater is required.

They are designed for repeated heating applications. Their modular design permits a variety of element shapes, sizes, and thermal capacities to choose from. They can be used bare (as supplied) or with the application of rigid or flexible insulation to retain heat and speed up the heat treating jobs
