Supported Applications
The Omega DB/DBW series consists of rugged, reliable, heavy-duty one-piece band heaters designed for cylindrical surfaces. Documented applications include heating barrels on plastic injection molding machines and extruders, die and die holder heating, burn-out ovens, heated kettles, fluidized beds, heat treating pipes, and autoclaves.
Operating Conditions & Performance
The series features a Chrome Steel sheath material with an operating process temperature up to 482°C (900°F). The maximum sheath temperature is rated at 649°C (1200°F). Power supply options are listed as 240/480V**, where the two 240V strip heating elements must be wired in series for 480V operation. Wattage ranges from 750 to 3250 watts across the available configurations.
Watt densities are based on the heated area of contact surface only, with values ranging from 24 W/In² to 42 W/In² depending on the specific model and barrel diameter. The series offers a flexible one-piece construction with spring-loaded clamping for uniform high-temperature capability.
Key Performance Parameters
- Sheath Material: Chrome Steel
- Maximum Sheath Temperature: 649°C (1200°F)
- Operating Process Temperature: Up to 482°C (900°F)
- Power Supply: 240/480V**
- Total Wattage Range: 750 to 3250 watts
Configuration Options
The DB/DBW series is available in two primary widths: 4 cm (1½") for the DB models and 6 cm (2½") for the DBW models. The heaters are configured to fit barrel diameters ranging from 13 cm (5) up to 32 cm (12½). Model numbers follow a specific guide format, such as DB-050772 or DBW-064152, indicating the series type, wattage, and barrel diameter.
Available Configurations by Width
- DB Series (4 cm / 1½" Wide): Covers barrel diameters from 13 cm (5) to 32 cm (12½). Wattage options include 770, 1000, 750, 1250, 1200, 1600, 1500, 1700, 1800, and 2100 watts.
- DBW Series (6 cm / 2½" Wide): Covers barrel diameters from 17 cm (6½) to 32 cm (12½). Wattage options include 1525, 1800, 2000, 2250, 2500, 2800, 2950, and 3250 watts.
Key Product Differences
The primary distinction between the two model families is the heater width. The DB series utilizes a 4 cm (1½") wide band, while the DBW series utilizes a wider 6 cm (2½") band to accommodate higher watt densities or larger surface areas on specific barrel diameters.
Model Number Structure
The model number guide is derived from ordering table headers and example numbers. The format generally follows [Series]-[Watts][Barrel Dia.]. For instance, the DB-050772 represents a 4 cm (1½") wide heater with 770 watts for a 13 cm (5) barrel diameter. The DBW-064152 represents a 6 cm (2½") wide heater with 1525 watts for a 17 cm (6½) barrel diameter.
Weight and Dimensions
Weighing between 0.7 kg (1.50 lb) and 1.8 kg (4.00 lb), the physical mass varies by wattage and width. The DB series weights range from 0.7 kg to 1.4 kg, while the heavier DBW series units weigh approximately 1.7 kg or 1.8 kg depending on the specific configuration.
