2. Infrared heater - Wikipedia

   en.wikipedia.org/wiki/Infrared_heater

   An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm.

3. Resistance wire - Wikipedia

   en.wikipedia.org/wiki/Resistance_wire

   Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures, up to 1,400 °C (2,550 °F). When used as a heating element, resistance wire is usually wound into coils.

4. Spray drying - Wikipedia

   en.wikipedia.org/wiki/Spray_drying

   The spray drying technique was first described in 1860 with the first spray dryer instrument patented by Samuel Percy in 1872. [citation needed] With time, the spray drying method grew in popularity, at first mainly for milk production in the 1920s and during World War II, when there was a need to reduce the weight and volume of food and other materials.

5. Friedrich Air Conditioning - Wikipedia

   en.wikipedia.org/wiki/Friedrich_Air_Conditioning

   The Q-Star had other variations, such as K-Star (ultra quiet), X-Star (digital) and TwinTemp (heat/cool). [12] The Q-Star was replaced by the "Q" chassis Kühl models in 2012. TwinTemp: Built in both "QuietMaster" and Q-Star configurations, these units provided both heating and cooling settings in one unit. They were replaced by the electric ...

6. Thermoelectric cooling - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_cooling

   Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

7. Compressed air dryer - Wikipedia

   en.wikipedia.org/wiki/Compressed_air_dryer

   Compressed air dryers are special types of filter systems that are specifically designed to remove the water that is inherent in compressed air. The compression of air raises its temperature and concentrates atmospheric contaminants, primarily water vapor, as resulting in air with elevated temperature and 100% relative humidity.
