Our Oxygen Detection Safety-pilot ODS

1. What is ODS Pilot?

ODS Pilot Burner is called ODS for short. When gas appliance is working in a unvented space for some time, the oxygen is involved in chemical reaction and produced CO2 and H2O when burning. In this case, the oxygen content in this unvented space is decreasing while CO2 content is increasing. People will feel uncomfortable when oxygen content arrives the level 16% to 17% or higher. It will even cause toxicosis when CO2 content arrives the level 4% or higher.

ODS Pilot Burner can avoid the above mentioned dangers and ensure the safe operation in unvented space. It will cut off the energy source so that gas appliance stops working to assure personal safety once oxygen content arrives the level 18.5% to 19.5% and CO2 content arrives the level 0.8% to 1.5%.

2. How the ODS works

The ODS system consists of three main components:

a precisely designed, oxygen sensitive pilot burner that regulates flame characteristics;

a thermocouple positioned in the mantle of the pilot flame; and

a safety shut-off valve.

The pilot is designed to be stable within a very narrow operating range. The thermocouple responds to changes in the pilot flame characteristics and, when heated, generates a millivoltage, which keeps the gas supply valve in the open position.

If low levels of oxygen are detected by the ODS system, the flame extinguishes. The loss of flame causes the thermocouple to cool. This cooling reduces the millivoltage, which causes the gas valve to return to its normally closed position, thus turning off the fuel supply to the appliance. The unit will not operate until the living space is properly ventilated and adequate oxygen is introduced, and the appliance is manually restarted.
