When choosing a radiant heater for a cabinet dryer, consider factors like cabinet size, material type, and desired drying temperature. Infrared radiant heaters are ideal due to their efficiency and versatility. They emit heat in the form of infrared radiation, directly heating surfaces in the cabinet, making them more efficient than convection heating. There are two main types of infrared radiant heaters: quartz and ceramic. Quartz heaters are more energy-efficient and can reach higher temperatures than ceramic heaters, making them suitable for high-temperature drying applications. Ceramic heaters are less expensive and have a longer lifespan, but may not reach as high temperatures as quartz heaters. The choice of radiant heater depends on the specific needs of the application, taking into account factors like cabinet size, material type, and desired temperature.
