In addition to selling industrial infrared heating solutions to OEMs, Huai'an Yinfrared Heating Tech has been a quality supplier of shortwave and mediumwave quartz halogen infrared lamp replacements for most infrared dryers, pre-dryers, ovens and comfort heaters. YFR not only provides replacement lamps, but often assists customers in determining the cause of premature infrared lamp failure.
We have extensive experience in replacing infrared lamps and extending lamp life through visits to various customers' facilities.
Some of the most common factors that lead to premature failure of shortwave quartz halogen lamps are as follow
Improper storage of lamps: One of the most common causes of breakage is also one of the most basic. Quartz lamps have very thin walls and are therefore very easy to damage. Slight collisions can cause tiny gaps in the quartz tube, which can lead to air leakage, filament oxidization and short circuits inside the infrared lamp. For gold-plated lamps, try not to touch them with your hands, and you should wear clean gloves ，because acidic sweat stains on your hands can corrode the gold-plated film on the surface of the lamps, so the lamps should be always be stored in the shipping container to prevent breakage and contamination. There is nothing more frustrating than looking for emergency replacement lamps on the shelf only to find that the stock is broken.
Improper Installation: Extra care should be taken when installing the lamp. Lamps should not be “forced” into position or clamped. This is especially true of longer lamps. Forced installation can create tiny cracks in the quartz that may go unnoticed but will eventually cause premature lamp failure.
Metamorphosis due to contamination: Oil, salt and other contaminants can cause quartz tubes to metamorphose, during which crystalline structures grow on the surface or inside the quartz. Crystallization causes the quartz to be opaque rather than transparent to infrared energy. This can trap too much energy in the quartz, causing the filament to overheat and resulting in lamp failure. Oil and salt from freehand operation, shop oil and dust are common sources of infrared lamp metamorphosis. All quartz halogen lamps should be visually inspected and wiped down with denatured alcohol before installation and energization.
Improper Power-Up: Use a soft-start silicon-controlled rectifier (SCR) when powering up the IR lamp. Minimizing temperature extremes will reduce filament expansion and contraction and extend lamp life. Full power produces high inrush currents that can damage wiring and blow fuses. A soft-start SCR raises the lamp voltage in pre-determined steps, gradually increasing the filament temperature and avoiding any potential damage to the filament.
Improper power connection: This last cause is also easily avoided. Infrared lamps, like all electrical products, must be properly connected to the power supply. Loose connections and undersized wires are common causes of shortened quartz halogen lamp life. Vigilance during installation and a system of regular inspections are good ways to avoid lamp damage due to improper connections.
