Violeds is a clean technology that provides robust disinfection on the surface of handrails using UV LED light. It is optimally designed to match the speed, area, and distance of the handrail to disinfect 99.9% of harmful viruses and bacteria in the areas exposed to the light.

EHC’s handrail sterilization solutions with Violeds technology have already been installed on escalators and moving walks around the world in a wide range of environments including airports, public transit systems, commercial buildings, shopping malls, department stores, healthcare facilities, sports venues, museums and government buildings. EHC recently supplied Violeds technology applied escalator handrails to Ted Stevens Anchorage International Airport in Alaska in the U.S. and James Armstrong Richardson International Airport in Winnipeg, Canada.

“In response to the growing demand for vertical transportation solutions incorporating clean, antibacterial and disinfection technologies, EHC has implemented the Violeds UVC disinfection module by Seoul Viosys, the leading UV LED company,” said Patrick Bothwell, Vice President of Sales, EHC Global. “Thousands of installations have already been completed and we anticipate continued demand in 2021 and beyond.”

An official from Seoul Viosys said, “As COVID-19 pandemic continues, interest in the prevention of multi-use facilities is greatly increasing. It is absolutely necessary to apply Violeds which has proven to disinfect 99.9% of new coronavirus, for elevators and escalators in public facilities such as airports, hospitals, shopping malls, sports stadiums, even in air conditioning systems.”

Violeds technology has been adopted for 2021 electronics models of such as refrigerators, drying machines, washing machines of the global top three brands and Violeds products are in mass production.
