Description
The DURAG D-UG660-20 appears to be a flame safeguard control unit used in industrial applications involving gas, oil, or coal-fired burners. Here’s a breakdown of its key characteristics based on previous searches and the information available online:
Function:
- The D-UG660-20 is designed to ensure the safe operation of burners by continuously monitoring the flame presence and providing control signals to shut off the fuel supply in case of flame loss.
- This helps prevent explosions, fires, and other safety hazards associated with uncontrolled fuel combustion.
**Features (based on similar models):
- Flame Detection: The D-UG660-20 likely utilizes an optical flame sensor to detect the presence and stability of the burner flame.
- Control Outputs: It provides relay outputs or other control signals to activate shut-off valves for the fuel supply if the flame is not detected within a preset time limit after burner ignition.
- Fuel Compatibility: The unit is likely suitable for use with gas, oil, or coal-fired burners based on the information found online.
- Presets: Some models might offer adjustable pre-settings for flame failure detection time (FFDT) and flame intensity switching threshold to optimize performance for different burner applications.
- Redundancy (possible): The “20” in the part number might suggest potential redundancy capabilities in some configurations. However, more information is needed to confirm this.
Applications (industrial combustion systems):
- Safety control in burners: The D-UG660-20 plays a critical role in ensuring burner safety by automatically stopping fuel flow in case of flame loss.
- Industrial heating systems: It is commonly used in industrial boilers, furnaces, and other combustion processes that rely on gas, oil, or coal for heat generation.
- Safety interlock systems: The D-UG660-20 can be integrated into broader safety interlock systems for industrial processes involving fuel combustion.
Finding More Information:
A specific datasheet for the D-UG660-20 might be difficult to find publicly due to the potential age of the product or focusing on safety-critical components. Here are some ways to learn more about its functionalities and compatibility:
- DURAG: While DURAG’s website doesn’t offer publicly available datasheets for all products, contacting their sales or technical support might be the most effective way to obtain detailed information on the D-UG660-20. They can provide details on features, specifications, redundancy capabilities (if applicable), and compatibility with your specific burner application.
- Industrial Parts Suppliers: Several suppliers sell replacement or surplus DURAG flame safeguard controls [supplier 1], [supplier 2], [supplier 3] (similar to previous searches, I cannot share URLs but searching the part number should lead you to product pages). These listings may offer:
- Limited information about the D-UG660-20’s functionalities (if available in their database).
- Compatibility details with specific burner models or combustion control systems (depending on the supplier information).
Additional Tips:
- Consider the context in which you encountered the D-UG660-20 (e.g., mentioned in a burner control system manual or used with a specific industrial furnace). This context can provide clues about its function within the combustion system.
- If you have access to the physical D-UG660-20 unit, look for any markings or labels on it that might indicate model variations or compatibility details for further searching.
Remember that flame safeguard controls are essential safety components in industrial combustion systems. It’s crucial to ensure you have the correct information and replacement parts from reputable sources when working with these devices.
