Certified Senior GUV Technician (CS-GUVT)

NALMCO, in partnership with the University of Maryland and others, has developed a Germicidal Ultraviolet (GUV) training and certification program. GUV technology is widely recognized for effectively disinfecting air and surfaces. As its use grows, proper training for those designing, installing, and maintaining GUV systems is essential. This program is the first step in promoting the safe and effective use of GUV.
