Ceramic Generators
Durable nichrome wire wound around a ceramic core is embedded in ceramic material and then fired in a kiln on site. Full temperature can be attained within five minutes. These generators are available in 500, 750, and 1000 watts.
Ideal substrates:
Coil-O-Rod or COR Generators
These elements deliver fast start-up in only three minutes and are available in 500, 750, 1000, 1500, 2000 and 3000 watts. Ideally suited for:
Both ceramic or COR elements have a 12" square aluminum reflector located behind the element to accurately direct the radiant heat towards the product, 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 product even after the oven has been on for hours. Reflectors need to be cleaned if product it hot to the touch.
Ceramic Panel Heaters
These heaters are used for heating large, massive or reflective products. Panel heaters are also a great option when space is limited. Watt densities of 25 watts per square inch can efficiently transfer heat at high rates as well as shorten oven cycles. In large products, the coatings may be cured without heating the entire mass of the part. 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 similar to a convection oven but with the speed of radiant heat.
Quartz Tubes
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 effectively target areas as small as 1"
Gas Catalytic Heaters
For surfaces that do not have adequate 3 phase electrical service, gas catalytic heaters are an option. These systems product a long wavelength output well suited to lower temperature applications, a powder coating on MDF board is an excellent example.
Infraround Heaters
Infraround series heaters are efficient, fast response, medium wavelength cylindrical infrared emitters 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. It is controlled with a K thermocouple embedded in the heater.
Series FS Heaters
The Series FS heaters are high watt density, up to 45 watts per inch square, heaters that also offer 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 keeps any product off of the face of this powerful heater.
