Utilizing innovative LED technology, it generates ultraviolet light in a mercury-free and non-toxic manner. The lamp size is Φ25mm(D) × 590mm(L), and each lamp contains 8 UVC LEDs arranged in 4 series of 2 parallel. It operates at a constant current of 700mA. Quartz lamps are commonly used in AHU large air conditioning systems with moisture and vertical air conditioners. By irradiating the filter with ultraviolet light, it effectively disinfects the surface of the filter and the flowing air.
DAL1 can be customized according to customer requirements for circuit design, electronic control, indicator lights, timers, etc. Currently, it has been installed in shopping centers, food courts, AHU large air conditioning systems in medical institutions, and vertical air conditioners in office buildings. When irradiating a 60(cm) × 60(cm) filter, the actual test showed an 84.46% reduction in colony count before and after the AHU large air conditioning system, equivalent to a 99.98% disinfection rate for COVID-19.
