MB-1-HEATER

Supported Applications

The Omega MB Series comprises one-piece and two-piece mica-insulated band heaters designed for industrial heating applications. Documented use cases include plastic molding machines, extruders, and autoclaves.

Operating Conditions & Performance

These heaters feature a die-formed aluminum-coated steel sheath enclosing nickel-chromium or nickel-chromium resistor wire wound on mica strips. The non-hygroscopic mica insulation provides long-term durability. Maximum barrel temperature is rated up to 399°C (750°F). Electrical power supply options include 120 to 240V for the MB-1 Series and 240/480V for the MB-2 Series.

Watt densities listed in specification tables are based on the heated area of contact surface only. The one-piece design is noted for providing uniform fit and quick temperature response, while two-piece configurations allow application on larger components.

Key Performance Parameters

• Max Barrel Temperature: Up to 399°C (750°F)
• Sheath Material: Die-formed aluminum-coated steel
• Insulation Type: Mica strips with nickel-chromium resistor wire
• Power Supply: 120 to 240V (MB-1 Series); 240/480V (MB-2 Series)

Configuration Options

The series supports a wide range of barrel diameters, heater widths, and power ratings. Model numbers follow the format MB. For example, model MB6J1J2P1 represents a 950 Watt, 240 or 480V heater.

Configurable Options

• Electrical Connections: Flexible Strand Terminals (Type A) or Heavy-Duty Anti-Torque Post Terminal (Type P)
• Housing Styles: One-piece design for uniform fit; two-piece design with stainless steel clamping band available in the MB-2 Series
• Sensor Elements: Nickel-chromium resistor wire wound on mica strips
• Voltage Configurations: 120V, 240V, and dual-voltage options (e.g., 240/480V)

Dimensional Envelope

The series covers barrel diameters ranging from small fractional sizes up to larger industrial dimensions. Specific model tables list configurations for barrel diameters including 1½, 2, and various inch fractions (e.g., 4⅞, 6¾) with corresponding heater widths.

Key Product Differences

The MB Series is divided into one-piece and two-piece constructions. The one-piece design offers a uniform fit suitable for standard installations requiring quick temperature response. Two-piece heaters utilize a stainless steel clamping band (MB-2 Series) to facilitate installation on larger components or where access constraints exist.

Terminal Types

Variants are distinguished by terminal configuration:

• Type A: Flexible Strand Terminals
• Type P: Heavy-Duty Anti-Torque Post Terminal

Series Distinctions

The MB-1 Series operates on 120 to 240V, while the MB-2 Series is configured for 240/480V applications. Model numbering reflects these distinctions along with barrel diameter codes and heater width specifications.
