OG-4000: Performance in a completely integrated package

Purfresh® OG-4000 Series generators provide customers with a compact yet powerful purification solution, with completely integrated packages for purifying air or process water. The generators are entirely self-contained, and include air preparation, oxygen concentration, ozone generation, distribution, and closed-loop PLC-based control and communication. All of these features are contained in a compact 24” x 24” x 11” cabinet that can be wall or skid mounted.

Efficient Ozone Production

OG-4000 Series generators produce efficient ozone output with high concentrations of ozone for maximum efficacy. Consistency and efficiency is obtained by integrating a complete air preparation subsystem that dries ambient air to -100ºF dew point and produces feed gas that includes 93 percent oxygen for more consistent and efficient ozone output. In addition, the corona discharge, air-cooled, ceramic flat plate ozone cell includes a precisely machined gap for consistent production, as well as sophisticated electronics for efficient power utilization, safe and quiet operation, and precise control. Output can easily be increased by adding a slave generator(s) controlled by another 4000 series system.

Powerful and Flexible Control

The OG-4000 Series generators come integrated with a programmable logic controller (PLC) that safely controls the entire system and gives operators flexibility in operation as well as communication. The control software includes 1% to 100% linear turndown for targeted manual ozone distribution, as well as the ability to set specific PID values for automated, closed-loop control response. The integrated PLC contains an Ethernet interface to communicate back to the Purfresh Intellipur™ Command Center for remote diagnostics and control, and the PLC can easily be integrated into a larger, plant-wide SCADA system.

Reliability and Simple Installation

Purfresh OG-4000 Series generators are simple to get up and running quickly. The generators are small, so they’re easy to mount on a wall or a skid, and they plug into a standard outlet. They are air-cooled, eliminating the plumbing and maintenance issues that come with water-cooled solutions. An air-preparation subsystem is included in the generator with an oxygen concentrator and a compressor, so no extra plumbing is necessary to connect the generator to an external compressor or house air.
