Tempsens Instruments (I) Pvt. Ltd.

Madri, Udaipur, Rajasthan

Tempsens offer Air Heaters which features high-temperature resistance wire open coil which is electrically isolated in a stainless steel sheath. Because the air being heated passes directly over the resistance wire, maximum heat transfer efficiency is achieved.
Air Heaters are used for heat staking, plastic welding, laminating, drying, heat sealing, and any other operation where air needs to be heated up 500C.

Advantages

• Fast heat uptime
• Increased Efficiency
• Easy installation
• Easy and inexpensive replacement

Construction

• Nickel chromium Resistance wire coils for maximum heater life evenly wounded for even heat distribution
• Mica Sheet for holding coils in place and are dielectric, lightweight, resilient and stable high temperatures.
• Mica Insulation having dielectric property to isolate high resistance coil from the sheath.
• Stainless Steel Sheath for corrosion resistance and high strength.
• Teflon coated control cable & thermistor cable for superior insulation and suitable for high voltage application.
• Glass wool insulation for high thermal resistance with low thermal conductivity.

Coil heaters offer high heating profile and high performance in compact spaces up to temperatures as high as 750°C. Available in Various cross-sections and sizes, coil heaters are not only straight and coil form but can be formed into almost in any geometrical shape.
Coil heaters can be closely wound to provide concentrated heat or can be stretched to fulfil distributed wattage needs. Coil heaters can also accommodate integrated thermocouples for precise temperature control and quick response. The thermocouple can be of type ‘J’ and type ‘K’ and can be terminated anywhere within the coil section.

Advantages

• High heating profile in compact spaces
• High performance and economical
• Precise Temperature control
• Fast response time
• Integrated Thermocouple
• Available in a variety of coiling and exit styles

Construction

• Nickel Chromium Resistance wire for maximum life
• High Purity magnesium oxide fill selected for maximum dielectric strength and thermal conductivity, highly compacted for maximum heat transfer
• Stainless steel sheath / Inconel sheath for oxidation and corrosion resistance in a wide variety of environment
• Thermocouple for precise temperature control (type ‘J’ and type ‘K’ thermocouple)

Applications

• Zinc Die Casting Machine
• Packaging Machines- Sealing bar and jaws
• Plastics and die casting industries -Machine nozzles
• Hot runner system – Nozzles, Bushings & Distribution plates

• Semiconductor manufacturing and wafer processing

Bundle Rod Heater consists of circular ceramic beads that hold the heating elements. They are designed for long life and maintenance-free operation. Designed & manufactured in low voltages for faster heating in order to achieve temperatures quickly, these heaters can be mounted horizontally or vertically. The element can be provided in ferritic alloys up to 1250° C and Ni Cr alloy up to 1100°C materials.

Construction

• Direct heating element wire
• Ceramic Disc : for hold the heating element & insulation
• Fiber Disc : for holds the terminal rod and prevent heat loss
• Center rod : for alignment & take weight of heater bundle

Advantages

• Carbon Dioxide emissions are reduced to avoid the corrosion of furnace gas to the heating element or avoid the contact of burning outcome.
• Convenient to control temperature, assemble and maintenance and easy to seal.
• Can be Horizontal or vertical mounted
• Better technical properties and longer working life
• Higher resistivity & surface load
• Free from oxide debris
• Cost-effective with High watt density output.

Application Areas

• For melting furnace and aluminum holding
• In steel industries, for galvanizing furnace
• In automotive industries, heat treatment furnace
• Annealing furnace
• Carburizing furnace
