This expanded line of UVC Emitters™ helps keep coils and drain pans clean and kills the microbes that grow and circulate in hvac systems, says the company. The standard double-ended fixtures now come in 18-, 24-, and 30-in. lengths and with a choice of voltage options to allow application in most any large system, claims the manufacturer. All fixtures feature an electronic power supply for optimum plasma stability and output, greater operating efficiency, longer life, and better energy performance, the company says. A new installation mechanism is said to allow easier assembly.
