OREC™ G Series Ozonators: Description
OREC™ G Series Ozonators
G Series Ozone Generator
The OREC™ G Series Oxygen / Dry Air (feed gas) Ozonators are designed to interface with a wide range of industrial applications. The ultra—compact, fiberglass reinforced cabinet makes the G Series suitable for demanding environments... aquaculture and agriculture, cooling tower and wastewater treatment, as well as many other commercial applications.
The G Series Ozonators incorporate an air—cooled titanium and ceramic reactor cell design with a high frequency variable controlled power supply. The G Type Ozone Generators offer a full range of output performance, from 3 g/hr to more than 60 g/hr... all in the same lightweight, sturdy, fiberglass reinforced, wall mountable enclosure.
The G Series Ozonators are among the most energy efficient in the industry! Their high concentration ozone output and low power consumption coupled with variable control; feed gas control; reactor back pressure gauge; power supply feed back output; and LED ozone output indicator.
G Series Ozonators can be controlled manually or remotely using a 0—10 VDC or 4—20 µA signal from an ozone analyzer, ozone process controller, ORP (oxidation reduction potential) controller or other control signal allows tremendous flexibility.
The OREC™ G Series Ozonators feature an integrated automatic cooling fan which keeps moisture out, even in cool or humid outdoor applications. The modular design combines the power supply with a titanium and ceramic reactor cell for improved field serviceability, providing years of trouble—free operation.
OREC™ G Series Ozonators: Technology
All OREC™ G Series Ozonators feature corona discharge ozone generators that produce comparatively high concentrations of ozone for the duration of a long, virtually service—free life. OREC™ Ultra Narrow Gap Corona Discharge
The titanium—ceramic, ultra—narrow—gap, corona discharge reactor cell is energized by a solid state power supply, providing proportional control of ozone output. The ultra—narrow—gap corona discharge reactor cell equates to energy efficient and responsive ozone generation.
OREC™ has combined ultra—narrow—gap technology with engineered, high frequency, pulse modulated power supplies and instantaneous amplitude modulated variable control to maximize ozone output efficiency and provide precise ozone concentrations.
The G Series Ozonators are constructed of ozone resistant components such as titanium electrodes, ceramic dielectrics, 316 stainless steel fittings, and Teflon® tubing to ensure reliability and maintenance—free performance. The Ozonators are air—cooled, employing large aluminum heat sinks and high volume fans for maximum heat transfer and optimal cooling, an important factor in improving ozone output.
Each OREC™ Ozonator is tested in a full range of operational conditions for ozone output and performance. OREC™ is unique, on a global basis, in having received Direct Traceability from the National Institute of Standards and Technology (NIST) and is ISO/IEC 17025 (A2LA) certified for ozone calibration!
