TOSHIBA Jacketed Low Pressure infrared emitters are specially designed for food warming application.
Fig.1 shows how TOSHIBA infrared emitters efficiently generate more Infrared Heat Energy but less visible light than classical lighting emitters.
Those are not only Low Pressure infrared emitter, but also additionally jacketed by 20mm dia. clear quartz sleeve :
The protection by clear quartz sleeve more securely ensures long life as well because of no direct contamination on infrared emitter inside from splashed sodium contained in foods. When such splashed sodium goes directly onto infrared emitter without protection being operated at high temperature, devitrification phenomenon is caused on quartz tube glass. Devitrification deteriorates not only quality of quartz over time, but also lifetime of infrared emitter itself.
TOSHIBA Jacketed Low Pressure infrared emitters protected by clear quartz sleeve therefore bring benefits of ;
