14,672 BTU/h Radiant Heating Performance

The TPI Corporation FSP-4348-3 delivers 4,300 W of electrical heating power, equivalent to approximately 14,972 BTU/h. Its infrared heating system transfers thermal energy through radiation, warming people and objects within the effective heating pattern rather than relying exclusively on heating the surrounding air. This approach is suitable for localized supplemental heating where warmth is required at a designated workstation or industrial work area. Actual comfort and heating performance depend on the distance between the heater and the target, ambient temperature, surrounding surfaces, air movement, and other environmental conditions. Position the heater according to the manufacturer's instructions to achieve suitable radiant coverage while maintaining the required safety clearances.

High-Density Flat-Panel Infrared Heating Technology

The TPI Corporation FSP-4348-3 uses a high-density, medium-wavelength flat-panel infrared emitter designed for heavy-duty radiant heating applications. The manufacturer specifies a published radiant efficiency of 78.5%, a symmetric 60-degree heat pattern, and an expected element life of 25,000 hours under specified operating conditions. The emitter transfers radiant energy to objects and people within the intended heating zone. Its gold-anodized aluminum housing supports reflectivity and corrosion resistance, while the heavy-duty wire guard helps protect the element and personnel. This radiant heating design does not require a fuel supply, combustion burner, or combustion exhaust system. Follow the manufacturer's installation and operating instructions, including specified clearances and electrical connection requirements.

Targeted Radiant Heat Distribution

The FSP-4348-3 uses its flat-panel emitter and reflective housing to direct radiant energy toward the intended work area. Its 60-degree symmetric heat pattern supports localized heating without requiring fan-forced air circulation. This configuration is useful for industrial workstations, maintenance tasks, and other applications where heat is required in a defined area. Because the unit uses radiant rather than forced-air heating, an airflow rating in cubic feet per minute (CFM) is not applicable. Position the heater to provide suitable radiant coverage, avoid obstructing the emitter, and maintain the manufacturer's required clearances from combustible materials and other objects.

Portable Construction & Flexible Placement

The TPI Corporation FSP-4348-3 features a steel handcart equipped with 6-inch wheels to facilitate transportation between suitable job-site and industrial locations. Its gold-anodized aluminum housing provides reflective and corrosion-resistant properties, while the heavy-duty wire guard helps protect the heating element. Manufacturer documentation lists approximate dimensions of 20 inches by 17.5 inches by 37.5 inches and an approximate unit weight of 32 lb for the FSP-43 series configuration. The portable cart supports repositioning as heating requirements change. Place the heater on a stable surface, maintain required clearances, and allow the unit to cool completely before moving or handling it.

Electrical Power & Energy Consumption

The TPI Corporation FSP-4348-3 operates on a 480 V electrical supply and is rated at 4,300 W. The manufacturer specifies compatibility with single-phase or three-phase operation when wired in the appropriate configuration. Published current ratings are 8.96 A for single-phase operation and 5.18 A for three-phase operation. The catalog identifies the model under manufacturer catalog number 04884602. Confirm the exact electrical configuration, frequency, nameplate current, grounding requirements, branch-circuit rating, and connection method before installation. Do not assume that a standard household plug or receptacle is suitable for this industrial heater. Electrical installation and phase configuration must follow the current manufacturer's wiring instructions and applicable electrical codes.

Radiant Comfort & Heating Control

The TPI Corporation FSP-4348-3 provides radiant heat while energized and correctly positioned toward the intended heating area. Its flat-panel emitter directs thermal energy toward people and objects within the radiation pattern, supporting localized heating without a fan or fuel-burning system. An integrated adjustable thermostat, digital temperature display, timer, or remote control is not confirmed as standard equipment for this model in the manufacturer's published documentation. TPI Corporation lists optional infrared control accessories for compatible FSP-series heaters, including tip-over protection, ground-fault sensing, and disconnect control. Confirm model compatibility, required electrical configuration, and accessory installation requirements with the manufacturer before ordering or installing optional controls.

Industrial, Manufacturing & Commercial Applications

The TPI Corporation FSP-4348-3 is intended for suitable industrial and commercial applications requiring localized electric radiant heat. Potential applications include manufacturing workstations, maintenance areas, workshops, assembly areas, and other environments where targeted heating is appropriate. Its 4,300 W heating capacity provides approximately 14,972 BTU/h of radiant output, while the portable handcart supports deployment between suitable work areas. The electric heating design eliminates the need for onsite fuel storage or a combustion exhaust system. Before selecting the heater, confirm that the intended application, electrical supply, environmental conditions, placement arrangement, and required clearances meet the manufacturer's specifications and applicable safety regulations.

Mobility & Deployment

The FSP-4348-3 features a steel handcart with 6-inch wheels designed to facilitate transportation to suitable job-site locations. This portable configuration supports repositioning as heating requirements change. Move the heater only when it is switched off, disconnected from electrical power, and sufficiently cool to handle.
