Technical specifications
| Hydraulic capacity | Hydraulic limits from 84 m³/h (OLS-02021) to 358 m³/h across the datasheet models; lamps, modules, banks and cabinets are set by the model code |
|---|---|
| Lamp type and life | Low pressure, high-output amalgam; expected lamp life 14,000 hours |
| Channel material | Stainless steel 304 / EN 1.4401 (as stated in the manufacturer datasheet; in the EN standard 1.4301 is 304 and 1.4401 is 316) |
| Safety | Snap-action limit switch shuts the system down when a module is removed |
| Control and integration | Calibrated UV sensor; real-time dose reading with flow and UVT meter inputs; lamp and ballast turn-down for lower power use; RS 485 interface for SCADA integration |
| Cleaning | Automatic wiper for quartz sleeve cleaning |
| Connection | Standard flange hole patterns (DN200 to DN400 in the datasheet models) |
Nuvonic OpenLine OLS is an open channel UV disinfection system for municipal and industrial wastewater discharge and reuse channels. It starts at a hydraulic limit of 84 m³/h (OLS-02021) and is built from lamp modules and banks, with low pressure high-output amalgam lamps of 14,000 hours expected life, an automatic wiper, an RS 485 SCADA connection and a snap-action limit switch safety interlock (source: Nuvonic OpenLine OLS datasheet). Mikron Proses (Üsküdar, Istanbul), the Nuvonic distributor in Turkey, supplies the system with channel design input, installation and commissioning.
OpenLine OLS is an economical and efficient open channel UV solution for wastewater effluent. It uses low pressure, high-output amalgam lamps, and its control system monitors lamp output, water quality and flow, so it draws only the power needed for the required performance. It is intended for small to medium sized plants that look for a low maintenance, easy to operate system. In a municipal wastewater process it sits after screening or grinding, grit removal, primary and secondary treatment and clarification, in the discharge or reuse water line.
Model structure: lamps, modules and banks
The model code (for example OLS-02021) is set by the number of lamps, modules, banks and cabinets. The smallest model, OLS-02021, has 4 lamps in a single module, bank and cabinet and a hydraulic limit of 84 m³/h. The datasheet models reach 358 m³/h (OLS-04041 and OLS-04042) with 16 to 32 lamps. In the datasheet the hydraulic limit follows the channel size (DN200 to DN400); a model with two banks (for example OLS-02022) carries the same hydraulic limit as its single-bank counterpart (OLS-02021) and has more lamps in the channel.
| Model | Hydraulic limit (m³/h) | Lamps | Modules | Banks | Channel connection |
|---|---|---|---|---|---|
| OLS-02021 | 84 | 4 | 1 | 1 | DN200 |
| OLS-03021 | 129 | 6 | 1 | 1 | DN250 |
| OLS-04021 | 174 | 8 | 1 | 1 | DN300 |
| OLS-03041 | 266 | 12 | 2 | 1 | DN350 |
| OLS-04041 | 358 | 16 | 2 | 1 | DN400 |
| OLS-02022 | 84 | 8 | 2 | 2 | DN200 |
| OLS-03022 | 129 | 12 | 2 | 2 | DN250 |
| OLS-04022 | 174 | 16 | 2 | 2 | DN300 |
| OLS-03042 | 266 | 24 | 4 | 2 | DN350 |
| OLS-04042 | 358 | 32 | 4 | 2 | DN400 |

Dose-based control
A calibrated UV sensor gives a real-time UV intensity reading and a built-in low UV dose alarm. When flow and UV transmittance (UVT) meters are connected, the system calculates the dose from the actual process conditions. Lamp and ballast turn-down avoids using more power than needed. The RS 485 interface connects directly to a SCADA or plant control system; the datasheet also lists Ethernet IP and Modbus TCP/IP at the communications port.
Robust design and safety
Parts are selected for the conditions of wastewater effluent, and the automatic wiper cleans the quartz sleeves regularly to keep performance uninterrupted. When any module is removed for maintenance, the snap-action limit switch stops the system automatically to protect the operator.
Which model and bank and module configuration suits a plant is decided from the target flow, the available channel dimensions and the discharge or reuse standard. Describe your requirement and we can size it together.
