Infrared (IR) technology is currently used in a wide range of industrial applications such as: The electronics industry for drying solder resists Food processing for browning and sterilization Coating/finishing for drying and curing Textiles for drying and sealing Plastics for softening Printing for drying Manufacturing/engineering for degreasing, preheating, and shrink fitting Infrared energy causes the…
When comparing heat sources used for drying processes there are a few variables: the primary carriers are usually solid or gaseous but may take the form of waves or other radio frequency technologies. Fossil fuels constitute the majority of commercially available energy sources used to generate heat. The supply of these fuels is diminishing, however,…
Electric heating elements in the form of coil, ribbon or rod (Fig. 1) made from alloys such as nickel-chromium, iron-chromium-aluminum and refractory metals are widely used throughout the heat-treating industry. They are found in both low- and high-temperature furnaces and perform well in cyclic-duty service. Let’s learn more. The temperature of a heating element and…
This article discusses two different ways that infrared (IR) heating can be used. One is a high-heat process requiring preheating of the tools/dies, and the other is a lower-temperature process where IR is cleaner and more efficient. Can infrared be used in your process to improve energy efficiency? Short-wave infrared emitters have allowed Mettis Aerospace…

Warming up an area not connected to a central heating system usually involves using either a wall heater or a cabinet unit heater. Deciding between using a wall heater or a cabinet unit heater usually comes down to these three things: Size of the space where the heater will be used Amount of space in…
Heatrex has helped with many different heating challenges in their history. Here is a case study written by Jonathan Newton about fire suppression tank heating. The Challenge Keep a large tank of water above freezing, so it is available at a moment’s notice. The sizing needed to take into account the fact that the tank…
