Glasco UV

What Glasco UV does

Glasco UV is a privately held, woman-owned manufacturer of ultraviolet (UV) water and wastewater disinfection systems, headquartered and produced at a single facility in Mahwah, New Jersey. The company designs and builds engineered UV reactors that expose water to germicidal light at 254 nm (and 185 nm for TOC reduction), with the differentiating NONCON 5000 Series using flow-through fluoropolymer (FEP/Teflon) tubes that position lamps in air rather than immersed in water to suppress fouling. The product portfolio spans five families — NONCON, Chambered, Vertical, Horizontal, and the IL Series — plus the GUV residential/commercial line, covering flow rates from roughly 0.25 GPM to 12 MGD per chamber, with specialized variants for liquid sugar disinfection (IL-LS) and hazardous oil-and-gas environments (IL-EXP).

The company's go-to-market combines an authorized reseller network for parts and service with direct enterprise sales on larger municipal, industrial, and aquaculture projects. Revenue is generated through custom-quoted hardware sales (each chamber treats up to 12 MGD and pricing varies with flow rate, application, and configuration), recurring replacement parts (UV lamps rated at 13,000 hours, quartz sleeves, ballasts), and service and repair contracts performed by authorized water-quality professionals. Customer concentration is spread across municipal water and wastewater utilities, industrial process water (food and beverage, pharmaceuticals, oil and gas, chemicals, aquaculture, zoos), and residential and small commercial point-of-use installations, with documented installations on every continent including Antarctica and Asia.

Glasco UV has been operating for over 50 years across three generations of family ownership, was founded in its current legal form (Glasco UV, LLC) in 2008 in New Jersey, and reports more than 1,500 cumulative installations worldwide. All chambered, vertical, and horizontal systems are biologically validated at HydroQual's Johnstown UV testing center, and the platform is US EPA accepted for drinking water and residential/commercial applications. The business is privately held with no parent company, no subsidiaries, no disclosed funding rounds, and no published financial results.

Core offering

Glasco UV manufactures ultraviolet (UV) water and wastewater disinfection systems, including NONCON fluoropolymer tube reactors, chambered vessels, vertical and horizontal open-channel systems, plus GUV residential/commercial and IL industrial series products. The company also sells replacement lamps, quartz sleeves, ballasts, and provides service and repair through authorized resellers and direct channels. Products serve municipal, industrial, aquaculture, and residential/commercial applications with flow rates ranging from 0.25 GPM to 12 MGD per chamber.

Product overview

Glasco UV is a manufacturer of UV (ultraviolet) water and wastewater disinfection systems. The product portfolio consists of four main product lines: NONCON (flow-through fluoropolymer tube systems), Chambered systems (pressurized vessel systems), Vertical systems (open channel vertical lamp systems), and Horizontal systems (open channel horizontal lamp systems). These are complemented by the GUV residential/commercial series and IL industrial series systems. The products serve municipal drinking water, municipal wastewater, industrial water, aquaculture, and residential/commercial applications. All systems use UV light at 254 nm (or 185 nm for TOC reduction) to disinfect water without chemicals. The company also offers specific variants for specialized applications including liquid sugar disinfection, explosion-proof environments, and aquaculture/fish water treatment.
