SSE-SSEM-SSNHM-HEATER

Supported Applications

The Omega SSE, SSEM, and SSNHM series comprises seamless strip heaters designed for industrial heating applications requiring rugged construction. These inline terminal units feature a seamless sheath design with two electrical terminals located at one end. The product overview identifies the series as offering premium quality construction suitable for general process heating where compact form factors are required.

Operating Conditions & Performance

The series operates on 120 or 240 Vac power supplies, with individual model wattage ranging from 200 to 2550 watts. Maximum operating temperatures depend on the sheath material: Iron sheaths are rated for 750°F, while Monel sheaths support up to 950°F. Watt density varies by dimension and series; documented values in specification tables range from 10 W/in² to 19 W/in² depending on the specific model configuration.

Configuration Options

The SSE, SSEM, and SSNHM families provide configurable options across sheath materials, dimensions, voltage ratings, and mounting features. Key selection parameters include:

• Sheath Materials: Rust-resisting Iron or Monel (SSNHM models are available only with a Monel sheath).
• Voltage Ratings: Models support 120 Vac or 240 Vac. Model numbers containing /120 or /240 indicate the specific voltage availability.
• Dimensions and Power: Widths are offered in 4 cm (1 11/16") or 2.9 cm (1 1/8"). Overall lengths with mounting tabs (Dimension A) range from 8¼" to 72", corresponding to power outputs between 200 and 2550 watts.
• Mounting Options: Standard configurations include a terminal base. Mounting tabs are available as an option by specifying "with mounting tabs" as a suffix, which incurs additional cost.
• Certifications: CSA approval is listed for the SSE series only.

Key Product Differences

The three model families differ primarily in sheath material availability and dimensional ranges. The SSNHM series is restricted to Monel sheaths, whereas both SSE (Rust-Resisting Iron) and SSEM (Monel Sheath) models are available across a broader range of dimensions listed in the specification tables. Model numbering follows specific patterns: SSNHM uses a dimension code followed by voltage (e.g., SSNHM-08/120), while SSE and SSEM use combined dimension codes with voltage suffixes (e.g., SSE-1437/120, SSEM-1541/120). Weight varies significantly across the series, ranging from 0.36 lb for smaller SSNHM units to 5.75 lb for larger SSE/SSEM configurations.
