PureLine Series Food & Beverage UV Systems

Nuvonic PureLine is a family of UV systems for food and beverage product and process water. Besides PureLine PQ AF, the variants on this page fall into five functional groups: basic disinfection, chlorine and chlorine dioxide removal, ozone removal, independently bioassayed assurance and the compact ECO design. All have a 316L stainless steel wetted chamber and FDA-approved wetted materials. Mikron Proses is the Nuvonic distributor in Turkey and provides application consulting for model selection.

D family: standard and hygienic basic disinfection

PureLine D AF (6 models, D AF 0003 to 0090, 115-600 W) provides basic disinfection with low pressure amalgam lamps, a wet UV monitor and a standard flanged connection; an optional tri-clamp hygienic chamber with a < 0.38 µm internal finish is available.

PureLine D EO H (3 models, D EO H 4/6/8, 4.5-6.8 kW) combines high capacity from a single medium pressure lamp with a tri-clamp hygienic chamber (< 0.8 µm Ra internal surface). It comes with a calibrated DVGW compliant dry sensor and a UVGuard window, and connects to SCADA or plant control systems through RS 485 Industrial Ethernet.

PureLine D PH (D PH 0070 to 0950, 1.6-33 kW) covers high-flow process lines with medium pressure designs of 1 to 8 lamps. Lamp life is 8,000 hours (4,000 hours for D PH 0240 and 0300), and the working fluid temperature is 1-60 °C (80 °C unwiped). It is CE marked and UL listed (E149108).

DC PH and DCD PH: chlorine and chlorine dioxide removal

PureLine DC PH (1.6-25.2 kW) removes free chlorine (HOCl and OCl⁻), and PureLine DCD PH (5 models, DCD PH 20 to 60, 4.2-25.2 kW) is designed specifically for chlorine dioxide (ClO₂) removal. Both use medium pressure lamps. Compared with activated carbon filtration or dosing of sodium metabisulphite or ferrous salt, they protect RO membranes from residual oxidant and bio-fouling without chemicals and without backwashing. Lamp life is 8,000 hours (4,000 hours for DC PH 250 and 300 and for DCD PH 40); both are CE marked and UL listed (E149108).

DO AF and DO PH: ozone removal

PureLine DO AF (3 models, DO AF 0005 to 0020, 345-700 W) uses low pressure lamps and PureLine DO PH (9 models, DO PH 0027 to 0400, 1.6-25.2 kW) uses medium pressure lamps. In source water that is ozonated to remove iron or manganese, or in process water lines, they remove residual ozone to produce deozonated water.

PQ family: independently bioassayed assurance

PQ AL (2 models, PQ AL 100/300, 2.4-7.2 kW, multi-lamp low pressure), PQ EO (5 models, PQ EO 4 to 12, 4.5-6.8 kW, single medium pressure lamp) with its hygienic variant PQ EO H+ (1 model, 9 kW, tri-clamp, < 0.8 µm) and PQ IL (6 models, PQ IL 450 to 14000, 5.6-52 kW, multi-lamp medium pressure) all come with third-party bioassayed dose equations. The PQ IL is tested in accordance with the USEPA UV Disinfection Guidance Manual. A calibrated dry UV sensor and flow and UVT meter inputs allow real-time dose calculation.

ECO: compact design with a low carbon footprint

PureLine ECO (12 models, ECO 4 to ECO 380, 4.1-385 m³/h, 90-2440 W, 1 to 7 lamps) offers a modern, compact alternative with low pressure amalgam lamps and a 7-inch touchscreen controller. It comes with a dry UV sensor, a PT100 temperature sensor and stepless 50-100% power adjustment; with the optional < 0.38 µm internal finish it can also be adapted to hygienic lines. The flow figures are the manufacturer’s capacity values under its reference conditions; the datasheet gives the details. ECO is CE marked and UL certified.

Choosing a variant

Which variant (basic or hygienic, chlorine or ozone removal, validation required or not) suits your process depends on the location of the line, the water quality and the validation requirement. Describe your application and we will select the right model together. For the selection logic, see the UV system selection guide; for maintenance, see UV lamp replacement. The whole range is listed under UV systems and on the Nuvonic brand page.
