Overview

The ETC6081 O2 Trim interface and software enables closed-loop oxygen trim on ETC controllers by integrating a flue-mounted oxygen probe. It continuously trims the fuel:air ratio based on measured flue oxygen to improve combustion efficiency and emissions performance in industrial and commercial burner and boiler applications.

Core functions

• Integrates a flue oxygen probe with ETC controllers to provide continuous O2 feedback
• Automatically trims the fuel:air ratio in real time to maintain efficient combustion under changing load
• Compensates for combustion variables such as barometric pressure, humidity, and gas pressure to stabilise excess air
• Provides an intuitive automatic trim set-up routine to reduce commissioning time
• Supports assignable oxygen and temperature alarm limits for monitoring and protection
• Enables boiler efficiency and calculated CO2 display and retransmission when the 6086 air temperature sensor is included in the peripheral configuration

Key technical features

• Oxygen trim interface and software layer for ETC controllers to enable closed-loop O2 trim
• Compatible for use across multiple fuels including natural gas, oil, and LPG
• Uses the ETC6083 oxygen probe design with no moving parts
• No pumped reference air required by the probe design
• Stainless steel probe construction for flue installation duty
• 6 micron sintered stainless steel filter for protection in flue environments
• Integrated thermocouple within the probe assembly
• Suitable for flue gas temperatures up to 540°C (1000°F)
• Probe size range to suit flue sizes from 0.3 m to 4.0 m across
• Fast probe response characteristics to support continuously modulating burners

Options and customization

• Select ETC6083 probe size to match the target flue size (0.3 m to 4.0 m across)
• Configure oxygen alarm limits to suit site requirements
• Configure temperature alarm limits to suit site requirements
• Add the 6086 air temperature sensor in the peripheral configuration to enable boiler efficiency and calculated CO2 display and retransmission

Typical applications

• Industrial and commercial boiler rooms using ETC controllers where efficiency and emissions depend on stable excess-air control
• Continuously modulating burners where fuel:air ratio can drift without closed-loop oxygen feedback
• Retrofit oxygen trim upgrades for ETC-controlled systems operating on natural gas, oil, or LPG
