Halogen (reflective) heating technology replicates the sun’s healthy rays, directly warming the person or object in front of the heater. Remarkably efficient, reflective heaters use less power to create the same amount of heat as traditional heaters.
Reflective infrared heaters are maximum sheath temperature, maximum AC voltage, watts, and maximum watt density. Maximum operating temperature is the maximum temperature that the sheath covering the heater may reach. The maximum sheath temperature does not represent the maximum temperature that a heated substance may reach. Maximum AC voltage represents the maximum AC voltage the heater can use. Watts represents the available wattage available from the heater. Maximum watt density is the amount of wattage per square inch that the heater is capable of delivering. Watt density is calculated by dividing the available wattage by the heated area. Watt density is a good measure of the heater's ability to quickly heat a substance. High watt density heaters should not be used with extremely viscous materials, materials that are not well-circulated, or explosive/volatile materials due to risk of fire.
Most infrared heater types will have a protective sheath that covers the heating elements. Many IR heaters will be available with many choices of sheath material. Sheath material for infrared heaters includes aluminum, brass, copper, iron, nickel alloy, stainless steel, and steel.
