Nuvonic PureLine PQ AF Food and Beverage UV System

Nuvonic (formerly Hanovia) PureLine PQ AF is a UV disinfection system for product and process waters in the food and beverage industry, with third-party bioassayed performance. The series runs from PQ AF 0005 to PQ AF 0090 (125-750 W), uses low pressure amalgam lamps with about 12,000 hours of expected life, a 316L (1.4404) stainless steel chamber and EPDM seals approved to FDA 21 CFR 177.2600 and EC 1935/2004. The maximum CIP temperature is 95°C to 130°C depending on the model (source: Nuvonic PureLine PQ AF datasheet). Mikron Proses (Üsküdar, Istanbul), the Nuvonic distributor in Turkey, supplies the system with installation and commissioning.

PureLine PQ AF is built for UV treatment of food and beverage waters whose dose equations and sizing have been independently derived and tested in accordance with the USEPA UV Disinfection Guidance Manual. A certified dry UV sensor measures the germicidal output, and a real-time RED dose reading with a low dose warning makes the performance easy to monitor and log. When flow and UV transmittance (UVT) meters are connected, the dose reading is based on the actual process conditions.

Hygienic design

The wetted parts are made of FDA-approved materials. The chamber is 316L (1.4404) stainless steel, and the ADI-free EPDM seals are approved to EC 1935/2004 and FDA 21 CFR 177.2600. An optional chamber with tri-clamp connections and an internal finish below 0.8 µm gives a sanitary design, suited to CIP procedures (95°C to 130°C hot water, depending on the model).

PureLine PQ AF models

Model	Maximum power (W)	Minimum T10 (%)
PQ AF 0005	125	60
PQ AF 0008	200	60
PQ AF 0016	350	60
PQ AF 0030	350	60
PQ AF 0090	750	60

The datasheet gives lamp power and minimum T10 per model, not flow capacity. Flow selection depends on UVT and the disinfection target, and is done per project.

Where it is used in the process

Bottled water lines are a typical case: the unit protects source and process water, limits bio-fouling in pre-treatment equipment and RO filters before the membrane, helps prevent contamination during CIP, and acts as a final protection step before bottling. The compact design allows installation on skids or retrofitting to an existing process.
