Ozone System for Room Disinfection
Last week I finished the installation of an Ozone System for room disinfection. The purpose of this Ozone System is to generate and control a high gaseous ozone level inside of 10 rooms for disinfection purposes. Using ozone in the gaseous form is always tricky due to safety concerns. Also, ozone gas is very unstable, and can cause difficulty measuring the ozone, and keeping it away from unwanted areas.
This Ozone System uses an Air Sep Oxygen Concentrator to provide oxygen, and two TG-40 Ozone Generators produce 100 g/hr of ozone for this application. A large control box is used to regulate ozone levels and distribute this ozone to 10 separate rooms. A timer is used to allow the user to control the time that ozone is delivered to the rooms, this ensures no personnel are within the area during operation. Ozone Monitors are used to measure ozone in each of the rooms. User settable relays integrated into the Ozone Monitors allow the user to set ozone levels, solenoid valves will then open and close based on these settings to start and stop ozone flow to each room. Flow meters are installed to ensure adequate ozone flow, and to regulate ozone flow to each of the 10 rooms. This allows the user to deliver more ozone to one room than another. A data logger is also used to log all ozone levels. This data logger is equipped with an Ethernet connections allowing the users to see the ozone levels real time from any location from their personal computer.
To measure and control ozone, ten ES-600 ozone meters are used. This is a cost effective and reliable Ozone Monitor for these applications. This was chosen due to the functions included on this monitor, and the long term sensor costs. This Ozone Monitor uses a 0.1 ppm safety relay that cannot be changed. This allows a safety relay to be integrated that will set a safety light to alert personnel that ozone levels are above the 0.1 ppm level. A second relay is used to allow the user to set ozone levels from 0-20 ppm. This relay is set with simple push buttons accessed by easily removing the cover.

Long term costs of this Ozone Monitor are also low. No calibration is ever necessary of the ozone sensor, and the sensors never need to be sent back to Ozone Solutions. The entire sensor is replaceable with a pre-calibrated sensor. When the new pre-calibrated sensor module is installed, the old sensor is disposed of. As the pre-calibrated sensor module carries a cost of $150, this is a very low cost Ozone Monitor to maintain over the long term.
