TOCLine ECO Series TOC Reduction UV System

Nuvonic TOCLine ECO is a UV system that reduces total organic carbon (TOC) in water with a special 185 nm synthetic UV lamp and a quartz sleeve. The lamp breaks down low molecular weight organic compounds by dissociating molecular bonds and by generating hydroxyl radicals from water molecules. The series has 7 models (T2 to T14) with 1 to 7 low pressure amalgam lamps (380-2430 W, 9,000 hours expected lamp life), a 316L (1.4404) stainless steel chamber, a 10 bar operating pressure and a CIP temperature of up to 95 °C with the cabinet electrically isolated. Mikron Proses, the Nuvonic distributor in Turkey, supplies the TOCLine ECO and provides application consulting, supply, installation and commissioning.

TOCLine ECO is intended for TOC reduction in ultrapure water lines for microelectronics and semiconductor production. It can be placed at different points of the treatment line, for example in the potable water supply line, after multimedia filters, at mixed bed deionizers (make-up and polisher) and after reverse osmosis.

7 models, 380 W to 2430 W

The seven models T2 to T14 cover a power range from 380 W to 2430 W with 1 to 7 lamps. The compact design suits installations with limited space; the unit can be fitted to skids or retrofitted to an existing process.

Hygienic design and CIP compatibility

The standard internal surface roughness is < 0.5 µm Ra, and < 0.38 µm Ra can be ordered as an option. The chamber has a removable tri-clamp end plate, and tri-clamp connections are available as an option. When the cabinet is electrically isolated, the chamber withstands CIP (clean-in-place) temperatures of up to 95 °C. Viton seals and a 10 bar operating pressure are standard. FDA-approved materials are used for all wetted parts.

Control and monitoring

The 7-inch touchscreen controller provides stepless power adjustment (max. 55% current), a fixed dose running mode, and monitoring of UV dose, water temperature, lamp running hours and flow rate (m³/h or GPM), and manages all alarms and warnings from a single screen. The 4-20 mA flow and T10 (UV transmittance) inputs allow the dose to be calculated from the actual process conditions.

Choosing a model

Which model and which internal finish suit your process depends on the target TOC reduction level, the flow rate and the hygiene 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.
