Hawthorne, NJ-based process heating equipment developers, Anderson Thermal Devices are inviting clients to review their full selection of industrial infrared (IR) lamps, including their shortwave twin tube heaters, which combine superior mechanical strength and several different wiring options with higher levels of radiant energy to offer standout heating performance for drying, curing, plastics processing, finishing, and a range of other applications. Process heating companies must carefully consider the return on investment offered with each new...

Twin tube lamps offer a versatile alternative to standard single tube lamps. In addition to allowing more watts per inch as compared to single tube lamps (making it possible to attain higher temperatures in a shorter time), twin tubes allow you to make the most out of particular physical constraints. The design of twin tube lamps makes them mechanically stronger than single tube lamps. The strength is most important when the lamps are longer than...

Process Information: Existing station printing line is at least 60 years old and the interstation hot air dryers are in poor condition and never had independent temperature or air flow control. The existing drying system would get the job done at 15 yards per minute which was acceptable before new “tip printing” and “wash coatings” became necessary to incorporate into the product mix on the last printing station. Problem: When applying the new tip printing...

ATD presents the latest chapter in our Infrared 101 series (covering the important elements of infrared process heating): Emissivity. By tailoring industrial infrared panel heaters to your applications, your team can achieve the ideal results during process heating applications. Emissivity is a critical element within this customization process. What is Emissivity? The emissivity of a working surface is its effectiveness in emitting energy as thermal radiation. The more emissive a material is, the greater the...

Coated industrial infrared lamps (shortwave and medium-wave) can offer a key efficiency advantage (compared to standard, non-coated T3 lamps, T4 lamps, or twin tube lamps). Certain coatings act as a reflector around the section of the lamp not aimed directly at the product, thus focusing the majority of the emissions toward your product. This creates opportunities for lower energy use or faster run times. While gold coated lamps offer this unidirectional advantage with 100% reflectivity,...

In addition to selling industrial infrared heating solutions to OEMs, Anderson Thermal Devices has been a source for replacement shortwave and medium wave quartz halogen infrared lamps for most infrared dryers, pre-dryers, ovens and comfort heaters. Not only will ATD supply replacement lamps, we often assist customers in determining why their IR lamps have been failing prematurely. Some of the most common factors that lead to premature shortwave quartz halogen lamp failure are as follows:...

If your process involves drying anything water-based, such as inks, solvents, or films, then you’re almost always going to want medium-wave industrial infrared lamps to handle the drying: The primary reason for using medium-wave radiation on water-based products is quite simple: As opposed to shortwave IR lamps (or Near IR heating solutions), which have a peak wavelength below 1.5 microns, the wavelength output of medium-wave lamps is between 2 and 4 microns. As it happens,...

Attempting to heat, dry, or cure items which are multi-colored can present a significant challenge. Different colors have significantly different wavelength profiles. White coatings, for instance, are far more reflective than black coatings. So, all things being equal, a white object would heat up under IR much more slowly than a black object. This effect is especially pronounced when dealing with shorter wavelengths. As a result, if an object being heated had a mix of...

Anderson Thermal Devices has partnered with Roller Design, LLC to create superior value for web processing applications. Our industrial heated rollers address our customers’ most persistent challenges: The result is a heated roller that is industry leading in its precision, efficiency, and durability. Our heated rollers achieve operating temperature quickly, reducing downtime considerably given today’s shorter product runs. Our precision controls ensure quality product and minimal scrap, allow processes to run with variable web widths,...

Occasionally, when working with clients, they express surprise that one of the mainstays of infrared lamps is the classic “quartz tube” halogen bulb. It was invented in the 1950s, so it seems odd that such a relatively old design would still be preferred for modern infrared emitters. However, sometimes classic designs are still the best. Halogen bulbs have a remarkable longevity, and are unlikely to be surpassed any time soon, in terms of price vs....
