Component Heaters

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 500°C.
 
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.

Hot Rod Cartridge Heaters are designed to provide uniform heating and excellent heat transfer rate throughout the heating surface. Facilitated with individually controllable heating zones, various process requirements such as zone-specific heating and distributed wattage requirement can be achieved with precise and uniform temperatures. Heaters are constructed with minimal spacing between sheath and heating elements to maintain lower internal temperatures which result in smaller-sized heaters operating at higher watt densities.

Constructed of high-grade Nickle Chromium resistance wire wounded on specially designed cores, separated from metal sheath using high purity magnesium oxide fill, all centered and tightly compacted in SS/Inconel tubing through the refined swaging process, results in heaters with a minimal air gap, high resistance to corrosion and oxidation, and increased life which makes Marathon make cartridge heaters best in class with high performance and longer durability.

Ceramic band heaters are medium-to-high temperature heaters that can deliver up to 1600°F (870°C). The heating element (Nichrome wire) is embedded in a flexible outer wall made of interlocking ceramic tiles, assembled like a brick wall. A ceramic fiber insulating mat and a stainless steel/ Aluminized Steel jacket cover this assembly. This makes them flexible, highly efficient, prevents heat loss and reduces electrical consumption by 20%. An energized ceramic heater that operates at 1200°F internally will have around 400°F on its outside shell. These durable heaters have versatile configurations which allow selection of clamping mechanism, terminal styles, holes and cut outs and perforations. Uniform heat distribution is an added advantage of ceramic band heaters. Limitations on the width of these heaters within a certain incremental range of sizes, is due to ceramic tiles that are available in specific lengths. Ceramic Band Heaters afford customers a means to heat large cylinders from intermediate to high temperatures without concern of failures due to "Hot-Spotting". A layer of thermal insulation reduces ambient heat loss and power consumption.

Advantages of Ceramic Band Heaters

• Lower Operating Cost
• Longer Heater Life
• Higher Operating Temperatures
• Flexible

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.

Famously known as “flexible heaters”, silicone rubber heaters are composed of fiberglass reinforced silicone rubbers that are rugged, moisture and chemical resistant, flame retardant, have high dielectric strength and are non toxic. Wire or etched foil heating circuits are positioned between two “wafers” of silicone which provides flexibility and strength. Design versatility permits zones of higher or lower heat concentration as needed. They are capable of flexing and will conform to contoured surfaces. They can also be pre-formed to complex shapes and can withstand mechanical shock and vibration.

Strip heaters, commonly called component or clamp heaters, based on the principle of convection air heating, use surface area to transfer heat effectively. Using most advanced heat technologies, strip heaters are an outstanding industrial heating product. It comprises of a heating element, a protective sleeve or sheath, and mounting hardware and can be clamped or bolted onto objects or solid surfaces. A coiled nickel chromium element wire is placed in the center of the heater. The element wire is then embedded in magnesium oxide (MgO)-based insulation and compacted into a solid mass creating excellent heat conductivity and high dielectric strength. The heater is then enclosed in desired sheathing. Suitable to work in 500 degree F temperatures, magnesium oxide is used for increasing efficiency. Temperatures can be controlled by using a temperature controller such as a thermostat. When using strip heaters, proper sheath material for resisting rusting or oxidation and suitable watt density of the element should be selected keeping in mind the application. These can be shaped and sized according to the use. A moderately inexpensive way of heating, strip heater is a tremendous solution to meet any budget.
