An infrared heater is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the infrared radiation ranges from 780 nm to 1 mm. The relationship between temperature and wavelength is expressed by the Stefan-Boltzmann Law. No contact or medium between the two bodies is needed for the energy transfer. A rough classification of infrared heaters is Efficiency of Infrared Heaters Theoretically, the efficiency of an infrared heater is 100% as it converts nearly all electrical energy into heat in the filament. The filament then emits its heat by infrared radiation that is directly or via a reflector impinging on the product to be heated. Some energy is lost due to conduction or convection.For practical applications, the efficiency of the infrared heater depends on matching the emitted wavelength and the absorption spectrum of the material to be heated. For example, the absorption spectrum for water has its peak at around 3000 nm. This means that emission from medium-wave or carbon infrared heaters are much better absorbed by water and water-based coatings than NIR or short -wave infrared radiation.The same is true for many plastics like PVC or polyethylene. Their peak absorption is around 3500 nm. On the other hand, some metals absorb only in the short -wave range and show a strong reflectivity in the medium and far infrared. This makes a careful selection of the right infrared heater type important for energy efficiency in the heating process.   Applications of Infrared Heaters IR heaters are used in industrial manufacturing processes including curing of coatings; heating of plastic prior to forming; plastic welding; processing glass; cooking and browning food. They are used when high temperatures are required, fast responses or temperature gradients are needed or products need to be heated in certain areas in a targeted way . Their application is difficult for objects with undercuts.They are also used to provide warmth to suckling animals whose mother cannot or will not provide them with natural warmth as well as to captive animals in zoos or veterinary clinics, especially for lizards and other reptiles, and tropical animals such as birds.IR heaters are used in low-temperature infrared saunas.

The infinite control switch gives infinite control for non-inductive loads up to 15 Amps on 120 or 240 V-AC (cannot be used with an external contactor). It can be turned either to left or right to adjust proper heat from 0-100% wattage with infinite control over the first 50% of total wattage.  Energized continuously in HI position, at other settings it delivers selected input level under control of a simple bimetal timer.  Only 3 mounting holes are necessary to install the INFINITE CONTROL SWITCH in customer supplied box or panel. It is designed for use at ambient temperatures up to 85°C. The model INF turns clockwise or counterclockwise.. A double-line disconnect is provided when the control is in the "Off" position. The permanent magnet provides snap action of contacts. Clean makes and breaks ensure long life of the fine silver contacts. The switch control is ambient compensated. It is designed for operation where ambient temperature does not exceed 85°C. The control contains a bimetal, which regulates the running cycles. This bimetal has a resistance wire wrapped around it, which is connected in parallel with the heating unit being controlled and cycles in unison with the heating element. When the switch is turned to "ON" position, the follower moves out and allows the contacts to close. This completes a circuit through a heating unit being controlled, and also to the resistance wire wrapped around the bimetal. At this time the steel armature is under the influence of the magnetic pull of magnet. As the resistance wire heats the bimetal, the bimetal flexes and forces are built up in it. When the force built up is equal to the magnetic pull of the magnet, the contacts open with a snap action and the steel armature will be pulled away from the magnetic field. This opens the contacts, which will cut off the power of the heating unit being controlled and will also disconnect the power to the bimetal-Resistance wire. As the bimetal cools, it will then flex in the opposite direction and the contacts will start moving closer together. At a certain point the magnetic pull will close with a snap action. This then will permit current to flow throughout the unit once again as the circuit is complete. A second bimetal is employed as an ambient temperature compensator to neutralize the effect of the surrounding temperatures on the control bimetal. These controls are designed to operate in locations where the maximum ambient temperature does not exceed approximately 85°C. The infinite control switch can control any resistive load up to 15 amps. It is possible to obtain a range of inputs to the element and/or load from approximately 5% at low- 100% at high, and infinite settings in between. Features Simplicity of design with no cams or levers to adjust, and no motor to burn out Automatic compensation for line voltage fluctuations up to ± 15% Bimetal acts at settings less than HI to limit electrical input and depress temperature Mechanical Bi-Metal Operation Knob Setting 0 - 100% Output Double Pole, Single Throw (DPST) Snap-Action Positive Break 120 or 240 V(Ac) depending on model 1,800 & 3,600 Watts Cannot be used with a contactor

S.M.E. Ceramic Heaters are specifically designed to replace and upgrade your Mica Band Heaters on your Injection and Extrusion machines. The body of the Ceramic Band heater is constructed of precision made segmented ceramics, which add flexibility and allow for easy installation. The ceramics are covered with insulation, which serves to lower the shroud temperatures and concentrates the heat towards the barrel. The end results are less wasted energy, a lower wattage requirement and a longer heater life. An additional metal jacket with CERAMIC FIBRE INSULATION inside it is wrapped around the heater to arrest the heat losses from the outer surface of the heater. This results in about 20 % of energy saving.   Materials Of Construction • Outer Sheath - Polished S.S.304• Ceramics - Steatite• Element - Resistance wire (Ni - 80 %, Cr-20%)• Termination - Metal Braided Fibre Glass wires• Insulation - Flexible Asbestos sheet or Ceramic Fibre covered with Aluminum foil to avoid black spots on                   outer sheath.   Manufacturing Depending upon the Volt and Wattage a suitable size of the resistance wire is selected as per the recommendation of the resistance wire manufacturer. The coil of the wire is then passed through the ceramics to get a bed of the ceramics .The size of the bed depends on the dia and the width of the heater. This bed is then fitted into S.S. 304 sheath after Al.foil and insulation. The element wire is terminated on a brass strip from where the lead wires are taken out further. These strips are covered with a ventilated terminal box. The heater is provided with a clamping device, which has a Cap Screw for easy, and even tightening of the heater on the barrel. A metallic jacket containing ceramic fibre is then wrapped around the heater

The SME Energy Regulator effects its control by periodically switching the power on and off, the ratio of the on time to the total time determining the average power input.As compared with a variable resistance, the energy regulator is in general cheaper, far less bulky, and applicable to any load up to its rated capacity. Moreover, the control is effected without the loss of energy associated with resistance control, is variable continuously from no load to full load and is substantially independent of mains voltage fluctuations up to about 20%. The energy regulator mainly consists of a heated bimetal and a snap-action switch (spring contact). Fig. 1 below will make the mode of operation clear. Is a bimetal strip holder carrying a cam follower whose function is to compensate for variations of ambient temperature Is a bimetal strip carrying a heater winding Is a snap-action switch operating the contact Is a knife edge about which the bimetal assembly can pivot Is a means of adjustment Normally the contact D is closed so that current flows through the heater winding on the bimetal and through the load. The bimetal warms and, in bending, opens the switch C, interrupting the current both to the heater winding and to the load. The bimetal then cools and the cycle is repeated. The ratio of the time during which the contacts are made, to the total time of the cycle, determines the average input. This ratio is controlled by the adjusting cam F. Clearly if the cam is set so that the contacts remain closed with the maximum deflection of the bimetal, the power will be permanently on; if the cam is turned until the contact D is open with the bimetal cold, the power will be permanently off. Between these two limits the input is continuously adjustable. Since the same voltage is applied to the energy regulator as is applied to the load, any variation will affect the two similarly, so that the average input is independent of applied voltage over a wide range. Features Long duty cycle and short intervals between heating = greater average output, e.g. for heating up Short duty cycle and long intervals between heating = smaller average output, e.g. for simmering The output of the load can be set to between 6% to 85% of the rated output. Select highest setting for full nominal rating (100%). Infinitely variable control of the power supply
