Twin Tube Medium Wave Infrared Heater which are the efficient sources of radiant energy. These heaters have heat up time of 50 seconds and cool down time of less that 15 seconds. The heaters are designed to offer excellent life characteristics even if operated. Continuously or intermittently with a quick heat & cool down response time. We can manufacture the quartz heater with 40 watts per square inch.

These are most versatile of all electric heating elements capable of being formed into virtually any configurations.The coil is made up of helically wound coil of Nickel Chrome wire which is housed in a tube of SS 304 Shealth.The space between the coil & tube is filled with specifically selected grain size of high purity Magnesium Oxide (MgO).This increases thermal conductivity, dielectric strength & heater life. The filled tube is then evenly compressed in swaging machine such that the diameter of the tube gets reduced. This holds the coil firmly in the centre of the tube.The terminals are SS screw type. Each end of the coil is welded to the screw’s inner end which remains covered in the tube and the other end of the screw protrudes outside the tube which is to be connected to the power supply.Tubular heater with in all 800 material is used when air is to be heated.The maximum watt density of 6 watts/Sq. cm is obtained. This heater is used when indirect heating is to be done.Tubular Heaters are available in wide variety of shapes, diameter and ratings. They can also be made as per customer’s requirement.They can also provided with SS or MS fins for rapid heating.Design Features :• Resistance Tolerance : + 10%, - 5%• Wattage Tolerance : +5%, -10%• Maximum Shealth Temp : SS: 650°C, Copper: 200°C, Incoloy:875°C• Maximum Voltage : 480 V AC• Maximum Current : 40 AMPTechnical Specification:Minimum Width 15.9 mmMinimum inside Diameter 20 mmNominal Watt Density 3-4 WI cm2Maximum Voltage 480 VACMaximum recommended voltage 240 VACMaximum Ampere 10 aMPResistance Tolerance +10%, -5%Wattage Tolerance +5%, -10%

Abtech offers Micro Tubular Heater which are adapted to a variety of applications. This is because it can be formed into any shape.Micro Tubular Heaters are swaged and compacted with magnesium oxide and a helical or straight resistance element. These heaters are used in tight spaces. In built thermocouple like J or K is also available. These are also availabe in round and square shealth• 360° heated area • Readily conforms to surface • Fast response and quick heat transfer • Helical coil design for superior performance • Resistance to corrision • Available with thermocouple

The modules are available in different sizes i.e 248mm (L) x 63mm(L), 122mm (L) x 63mm (W) with the power ratings from 250 to 1000W & 125 to 650W ...     Features :• Good radiant efficiency up to 80%• Very rapid Heat-up, cool-down time 30 to 60 seconds• Watt density up to 40 watts /sq.inch• Infrared wavelength Range from 2.5 to 3.0 mm• Lower power consumptionApplications :• Thermo Forming• Plastic Forming• Lamination• Shrink Packaging tunnels• Curing rubber• Drying textiles• Drying lacquers and paints

Abtech Heaters & Controllers offers ceramic band heaters that are specifically designed and manufactured to meet the ever increasing demand for energy conservation and to improve operation efficiency. The ceramic Band Heaters transmit heat through both conduction and radiation. The construction is helically wound resistance coil of Nickel chrome wire. This coil is passed through the holes in specially designed ceramic bricks in such a way that the coil is evenly stretched and flexible ceramic heating mat gets formed.   Design Features :• Energy Saving• Minimal heat loss• Buil-in thermal insulation• Uniform temperature• Maximum flexibility for easy installation• Longer heater lifeTechnical Specification:Maximum Voltage 480 V ACMaximum Current 25 AmpMaximum temperature 7600cResistance Tolerence +10% , -5%Maximum Watt density 7 W/cm2Wattage Tolerance +5% , -10%Shealth Material Outer 55, inner MS or as per requirementInsulation Material 1/4" thick Ceramic Fiber blanketOverall Thickness 10mm or 5/8" Minimum width 1"Minimum Diameter 2"Maximum Diameter 44"

Abtech Heaters & Controllers offers Cartridge Heaters both High Watt and Low Watt density. These heaters are designed for a long life and outstanding performance.Features :• Nickel - Chromium resistance wire gives even and efficient heat transfer to the sheath• Heavy wall Incoloy or SS 316 sheath provides maximum protection against oxidations and corrosion• High Purity magnesium oxide is thoroughly compacted to give the excellent heat transfer• Helical coil design for superior performance• Available with inbuilt thermocouple• Termination of heaters can be made as per customers choice

Ceramic Strip heater is made of Nickel Chrome Resistance wire helically wound coil, which is placed in the heater. The coil is precisely strung through the ceramic insulator & then is mechanically connected to the screw terminals or lead wires as required. The outer body is made of SS304 Stainless Steel Shealth which provides physical strength and resistance to high temperature up to 600°C. The resistance wire coil is housed in specially designed ceramic insulator. The Ceramic Strip Heaters are availabe with or without mounting holes.These heaters are also available with fins for air heating applications. The fins have been specially designed to provide maximum surface contact for good heat dissipation thus resulting in rapid heat transfer to the air.Performance Ratings:Maximum Shealth Temp 650° CNominal Watt Density 20W/in (3.1W/cm)Electrical RatingsMaximum Voltage 480V AC(dependent on desing parameters)Maximum Recommended Voltage w/Leads 240V ACMaximum Amperage Lead wire termination, 10 AmpScrew Terminations 10-32 UNF 25 ampResistance Tolerance +10%, -5%Wattage Tolerance +5%, -10%Physical Size Construction Limitation:Width 5/8" wide heater +.000, -.005"1" and 11/2" wide heaters +.000, -. 010"Thickness 1/4" Thick heaters +.000, -. 005"5/16" & 3/8" thick heaters +.000, -.008"Length Upto 24" +/- 1/16"Over 24" +/- 1/8"Mounting Slot Sizes Standard 5/16" x 1/2"Special 1/2" x 5/8"Applications• Ovens• Hot Plates• Moulds & Dies• Baking• Incubators• Air Heating
