IR Heating Applications

High temperature on sealed part will shorten infrared lamp life

High temperature on sealed part will shorten infrared lamp life

Firstly let us know the types of quartz infrared lamps. The end of quartz needs to be seald and this kind of infrared quartz lamp is vacuum sealing. The sealing infrared lamp have a fast response time within 1-2 seconds, and the radiation energy is stable with more than 5000 hours working life, but we should keep the temperature on sealed part as lower as we can, especially for oven drying.    Higher temperature over 350℃ on sealed part will damage the lamps. The lamps will be broken slowly or quickly due to different oxidation levels of sealing part. The graph shows the relationship between sealing temperature and infrared lamp life. Higher temperature on sealed part, lower working life of IR lamps. Lower temperature on sealed part, longer working life of IR quartz sealed lamps.   As you can see from our lamp photo, a molybdenum foil is sealed inside of quartz and there is molybdenum rod connects the molybdenum foil and outside cables.The foil is not completely air insulation, there is a very small gap between the quartz seal and the outer cables. Through this gap, very small quantities of air can be introduced into the seal part. Molybdenum foil can easily oxidizes when temperatures rise above 350 degrees C.

Why Promote Quartz Radiant Drying IR Lamp?

Why Promote Quartz Radiant Drying IR Lamp?

Our quartz IR lamps are designed to provide maximum efficiency and reliability for all industrial heating application. Our IR lamps are energy efficient and can provide up to 50% more energy savings compared to traditional heating methods. Our IR lamps are also easy to install and maintain, making them the perfect choice for industrial heating projects. Try our quartz tube radiant infrared lamps today and experience the difference!                                                                                        Why should we promote the use of infrared heat lamps? Because infrared quartz drying IR lamps has four excellent characteristics of "efficient, energy-saving, accurate temperature control and environmental protection".    1. Efficient means fast heating, infrared radiation does not need to contact the product and does not require the intermediate medium to transfer heat compared with hot air, ceramic heaters, gas heaters or metal heaters. The radiant energy of infrared lamp is directly absorbed by material molecules, and the energy density of infrared lamp is very large, the surface temperature of the heated materials will increase quickly. This infrared heating speed is much higher and efficient than the speed of conduction and convection. The latter requires molecular collisions, which are transferred step by step through the conversion of kinetic and potential energy.        Infrared heating has certain penetrability. The wavelength of shortwave infrared heater lamp can penetrate the surface of an object to a certain depth, and when the molecules within this depth absorb the shortwave infrared, they heat from the inside to the outside at the same time. This has great advantages over conduction and convection, not only fast heating, but also to a large extent avoids the phenomenon of surface sealing and blistering.         2. Energy saving means saving money, infrared quartz lamps can be precisely matched to the heated material, that is, effectively absorbed by the material. Different objects different matched IR radiation wavelength-IR lamp Short wave (0.9~1.4μm), Fast response medium wave (1.4~2.0μm), Carbon medium wave (2.0~4.0μm), Medium wave (2.2~4.0μm).     when heating the same size and quantity of heating objects, quartz heating infrared lamp can greatly reduce energy consumption. The infrared heating is more surface heating. As mentioned above, medium wave infrared heater lamp heats the surface of an object very rapidly, so there is a large temperature difference between the surface and the interior of the object. This is a great advantage for the purpose of rapidly heating the surface of an object, as this does not cause large changes in the bulk temperature of the material. Energy saving without having a big impact on the humidity, chemical properties, stress, etc. of the object. But it also has the disadvantage, that is uneven heating for objects with irregular shapes, the disadvantage will cause temperature differences. At this time, we can have hot air in to get a uniform heating with infrared heater lamps.         3. Fast response, adjustable heating temperature   Our quartz infrared lamps are resistnace load and can be adjusted the output power by SCR regulator with accurate ±1℃ heating temperature. For example, if we need 120℃ heating temperature, and the real-time temperature is 115℃ from the temperature sensor, then the temp sensor will return the singal to SCR units and SCR will raise up the heating output power. In opposite,  if the real-time temperature is 123℃ from the temperature sensor, then the temp sensor will return the singal to SCR units and SCR will lower the heating output power of quartz infrared lamps. As the following diagrams, ΔT is smaller and more stable heating temperature we have.           In above, SCR regulators can help us save the output energy and control the heating temperature for different heating applications or heating zones with our infrared heating lamps.                                             4. Environmental Protection, in the process of manufacturing, use, and abandoned infrared radiation lamps is relatively small on the environment. Infrared radiation lamps do not use materials that are harmful to the environment: the impact of the environment during the manufacturing process is small. Infrared radiation lamps consume relatively clean electricity in working, and has no harmful emissions in the process of use.   For a successful heating process, it is important to select a suitable infrared lamp with wavelength, shape and heating power match the product being heated. Precise matching ensures that infrared radiation is quickly converted into heat in the product without transferring unnecessary heat to the surroundings, saving time and money.

Infrared Heating With Microwave For Industrial Drying

Infrared Heating With Microwave For Industrial Drying

Infrared heating can be used together with hot air heating for industrial drying process to get more uniform heat. Besides, infrared heating can also be used with microwave for industrial high temperature sterilization disinfection, and the production of ingredients drying. For example, the high temperature disinfection of various glass bottles, the drying of tea, the drying of soy products, dried spices, dried meat, and drying of mushrooms, fruits and vegetables.                  Infrared heating needs a small volume to distribute heating lamps and our infrared lamps are fast response. At the same time, it can be accurately regulated by PLC or SCR, which can be used as the preheating of tunnel drying to improve the production speed. Our infrared lamps can also be used as a mid -term constant temperature heating in drying machine. Infrared heating has a stable power output and is not affected by the outside air, so that the heated objects can obtain a uniform heating temperature.   Infrared quartz lamps have special heating advantages compared to traditional heat sources, such as hot air, ceramic heaters, gas heaters or metal heaters. Infrared quartz heating lamps can deliver large amounts of radiation energy directly to heated objects, and the emit wavelength can be precisely matched to materials absorb, and the heating length and shapes are custom design.

Does turn on/off frequently will affect working life of infrared heat lamps?

Does turn on/off frequently will affect working life of infrared heat lamps?

When heating with infrared lamps, does turn on/off heating frequently will affect the working life of infrared heat lamps?                                                                                           The answer is yes.   In circuit science, the moment the load is powered on, a large current is usually generated, which is the impact current. When starting infrared heating lamp, there is also a current impact. The start-up current is generally 4-7 times that of the rated current. If IR heat lamp is powered on and off frequently, the conductive element of the infrared heating tube will causes damage frequently, so we do not agree with the operation by turn on/off frequently our lamps.         Case 1: T-shirts thermal transfer equipment with 220V 1600W quartz infrared heeat lamp, basically needs to be switched on and off lamp one time every 10 seconds, the heating equipment work 24 hours every day, this customer will turn on and off lamps 360 times every hour and 8640 times every day, especially the heating equipment which are using R7s connection sockets, turning on and off infrared heating so frequently will damage the connection parts between R7s socket and our infrared lamp.        Case 2: There was one customer who switched on and off our twin tube IR lamps 3 times in 1 second, the operation is definitely not good to lamp, because heating elements cannot be restored and they will gradually produce volatile impurities.   Case 3: Customers use medium wave infrared heating lamp. They want to turn off the heating when no workpiece on the conveyor. When the workpiece needs to be heated, the heating is turned on. If they turn on and off frequently, for medium wave infrared lamp, we do not recommend the customer to do this. Because the response time of medium wave heating lamp takes 1-4 minutes. If the workpiece is heated at this time, the heating temperature of the workpiece may not reach the required temperature, which will affect production efficiency.     If you really need to turn on and off IR heating lamps frequently for researches, we can enhance the conductive components of the lamp to increase the working life of the lamp.   Different customers have different control ways during infrared heating. If the heating involves frequent startups, we more hope that you use PLC or our SCR to adjust power output percentage of the way to control. The important that our SCR power regulator can control the starting current from 0 to rated current and no more impact on our infrared heat lamps.
