CRFP

Supported Applications

The Omega CRFP Series consists of flat plate ceramic radiant heaters designed for high-temperature applications requiring rapid heat-up and cool-down. These vacuum-formed ceramic fiber units utilize helically wound iron-chrome-aluminum ribbon elements mounted in ridges to dissipate heat in three directions, increasing the effective radiant surface area. The series is intended for radiant heat only; direct contact between material and the heater face must be avoided.

Documented applications include:

• Pipe heating
• Process air heating
• Tube furnaces
• Heat treating furnaces
• Fluidized bed furnaces

Operating Conditions & Performance

The CRFP Series is rated for a maximum operating temperature of 1800 °F (900 °C). The heaters are constructed from high-quality, high-purity vacuum-formed ceramic with a low sodium inorganic bond. Due to the materials used, care must be taken during handling.

Performance characteristics include:

• Maximum Operating Temperature: 1800°F (900°C)
• Resistance Tolerance: ±5%
• Shrinkage: Up to 4% for temperatures up to 980°C
• Dimensional Variance: Potential variance of ±1/4" in heater size

The series supports power supplies of 120 and 240 Vac single and dual circuits. Specific models utilize dual 240 Vac circuits, indicated by specific model suffixes or foot notes.

Configuration Options

The CRFP Series offers a broad range of configurations defined by wattage, voltage, dimensions (A, B, C, D), and the presence of flanges. Two flat plate fiber heaters matched with 2 flanged flat plate fiber heaters to form a box with 4 heated sides.

Power and Voltage Options

The series covers power ratings from 300 Watts up to 6200 Watts across various voltages:

• Voltage: 120 Vac and 240 Vac (single and dual circuits)
• Dual Circuit Configurations: Specific high-wattage models operate on dual 240 Vac circuits.

Housing and Mounting Options

Variants are available with or without unheated flanges. The model number suffix indicates the configuration:

• Without Flanges: Standard flat plate units.
• With flanges (-C): Units complete with attached flanges; Flat plate with unheated flanges have 51 mm (2") wide unheated flanges on each side of heated area.

Electrical Connections

Mechanical terminations such as SPLIT BOLT connections or TERMINAL STRIPS are recommended. Lead wires may be bent to specific needs, but care must be taken to avoid excessive stress on the junction. Polarity must be observed; L1 and L2 should never be connected adjacent to each other.

Dimensional Envelope

The series provides various lengths (A Dim) ranging from 6 inches to 24 inches, with corresponding widths (B Dim) and (D Dim), and heights (C Dim). Specific dimensions vary by model; refer to the specification table for exact A, B, C, D values in inches.
