Question:

I would like to know when I should replace my catalytic ozone destructor with a new one? I know what the destructor is made of - how long does it function normally?

Answer:

=== Thank you for your question(s).

=== Ozone Destructor we designed and produce uses a very simple principle - ozone channeled into the destructor is passing trough the catalytic agent. Direct contact between the agent and ozone results in oxidation process converting ozone (O₃) to oxygen (O₂) which is then released from the destructor.

Safety of our clients is very important to us as well as product reliability. Consequently, during the design process we took following steps:

1). we selected 1/2" clear PVC tube for the tubular section of destructor because of good handling properties, excessive thickness of the wall and durability. Clarity of the tube allowing the visual control of the catalytic agent inside the destructor was also important....

2). we selected 1/2" SCH 40 PVC end cups because of good handling properties, excessive thickness of the wall and durability.

3). we determined minimum thickness of catalytic agent bed (column) needed for effective destruction of ozone. This was done by simulating various ozone applications and monitoring off-gas coming out from ozone destructor with ozone gas monitor.

4). after minimum required thickness of agent bed was determined (3.25"), we used safety factor K=3 to determine the actual length of the destructor (3.25" x 3 => 9.75")

Under normal operating conditions, the destructor will provide years of service, actually, in theory there should not be any time limit...and from our personal experience based on a track record starting back in 1994 & over 1300 systems sold and no "destructor problem" I would be inclined to believe that ozone destructor we designed and produce is extremely reliable.

Compromised function of the destructor would be exhibited by inadequate ozone conversion to oxygen and consequent ozone leakage. Most humans can detect ozone concentrations in air as low as 0.02 PPM - well bellow 0.05 PPM limit.
