Blasdel utilizes many different industrial infrared heaters and reflectors to determine the best outcome for your process. Our test lab has multiple ovens with a variety of infrared heaters as listed below. Infrared heaters are also called emitters or generators.
Blasdel ceramic generators are infrared heaters manufactured onsite. They are made of durable nichrome wire wound around a ceramic core. The core is embedded in ceramic material and then fired in a kiln. Full temperature can be attained within five minutes. These generators are available in 500, 750, and 1000 watts. These infrared heaters are 90% heat transfer efficient by producing medium wave infrared heat, as well as convection heat.
Ideally suited for:
Blasdel Coil-O-Rods are infrared heaters that deliver fast start-up in only three minutes and are available in 500, 750, 1000, 1500, 2000 and 3000 watts.
Ideally suited for:
These heaters are 90% heat transfer efficient by producing medium wave infrared as well as convection heat. Also, our heaters/emitters are used for replacement on other electric infrared ovens that have similar emitters.
Both ceramic or COR elements have a 12″ square aluminum reflector located behind the element to accurately direct the radiant heat towards the product, in a uniform pattern, providing an effective target zone. Aluminum is second only to gold in its ability to reflect the radiant heat towards the product. If the reflector is clean and efficient, you can touch the reflector even after the oven has been on for hours. Reflectors need to be cleaned if the reflector is hot to the touch. Blasdel has the capability of cleaning your aluminum or stainless oven reflectors. We have disposable reflectors as well. Let us know about your reflector needs.
Ceramic panel infrared heaters are used for heating large, massive or reflective products. Panel heaters are also a great option when space is limited. Watt densities up to 25 watts per square inch efficiently transfer heat at high rates as well as shorten oven cycles. In large products, infrared cures the coatings without heating the entire mass of the part depending on the substrate and coating. This means the cooling time is shortened as well.
Ceramic Panel Heaters create a great deal of convection heat along with radiant energy. Complex parts, hidden areas, and reflective materials are heated in a similar process of a convection oven, but with the speed of radiant heat.
Infraround series heaters are efficient, fast response, medium wavelength cylindrical infrared emitters. They are designed for use in industrial heating applications for wire and cable, tubing, pipe, pultrusions, etc. This heater is excellent for high temperature applications with a fast on/off response time. The hinged design allows for easy maintenance. It uses a serpentine metallic element and is controlled with a K thermocouple embedded in the heater.
The FS Series heaters are high watt density, up to 45 watts per inch square, offering on/off response times of about 30 seconds. FS heaters use a serpentine metallic element. They are appropriate for high temperature applications with more delicate substrates that would be damaged if the production line should stop. Temperature is controlled with a K thermocouple and a set point temperature controller. With proper oven design, a moderate amount of convection heat can be retained, maximizing both radiant and convection heat. A protective stainless steel face screen helps keep product that may fall off from the face of this powerful heater.
The V-Series is utilized in applications that require high power, tight process control, and fast heat-up/cool-down. V-Series have fast on/off time which is excellent for web and textile applications. V-Series heaters have similar response time to short wavelength infrared but are more durable.
For surfaces that do not have adequate 3 phase electrical service, gas catalytic heaters are an option. These systems produce a long wavelength output well suited to lower temperature applications. Gas catalytic works very well on large complex shapes, as well. Types of applications include powder coating and liquid paint curing.
Quartz tubes are occasionally used in systems designed by Blasdel. Although this type of emitter is fragile, requiring relatively high maintenance, it is capable of extremely high heat and offers nearly instant on/off cycles. These tubes also provide an excellent option when heating small parts or small areas of a product. Reflector designs can be added to effectively target areas as small as 1″.
