The OCS-OZW 250 PRO is the flagship model of the series, developed for industrial fruit and vegetable washing lines requiring high hygiene standards and full traceability. The dual-tank (2×125 L, 250 L) structure is paired with an oxygen concentrator feed to achieve a higher and more stable ozone concentration.
The distinguishing feature of the PRO model is that it measures both the dissolved ozone in the wash water and the ozone concentration in the ambient air simultaneously, using separate sensors. This dual measurement secures both process quality (target ppm in the water) and worker safety (0.1 ppm OHS limit) at the same time. A catalytic ozone destruction unit fully neutralises the off-gas leaving the reactor, preventing free ozone from entering the surrounding air.
With full PLC automation, product-based recipe management, and a documentable process report for HACCP, the PRO model is designed for export-oriented facilities subject to audit.
Note: Under appropriate process conditions, ozone contributes to the reduction of certain pesticide residues; the removal rate varies depending on the pesticide's chemical structure, ozone concentration, and contact time.

1. What is the purpose of dual ozone measurement?
The liquid-phase measurement confirms process quality (target ppm); the ambient air measurement continuously monitors worker safety (0.1 ppm OHS limit). Together they secure both quality and safety.
2. What is the difference from the Standard 250 model?
The PRO model differs with an oxygen-fed 10 g/h generator, a microbubble gas-liquid contact system, dual ozone measurement, a standard 316L body, and a HACCP process report.
3. Does the system completely remove pesticide residues?
No. Under appropriate process conditions, ozone contributes to the reduction of certain pesticide residues; the removal rate depends on the pesticide's structure and ozonation conditions.
4. What does the HACCP process report cover?
It is a process report based on the dissolved ozone, ambient ozone, and recipe data logged by the system, usable as documentation during audits.
5. How does the water recovery module work?
It is an optional module combining filtration, ozone injection, and ORP-based dose control, allowing wash water to be safely reused across multiple cycles.
