68,300 BTU/h Heating Performance for Commercial & Industrial Applications

The TPI Corporation 5100 Series P3P5120CA1N delivers a rated heating capacity of approximately 68,300 BTU/h from its 20 kW electric heating system. This output supports supplemental heating in appropriately sized warehouses, storage rooms, workshops, and industrial facilities. The manufacturer specifies a temperature rise of approximately 57°F under the stated operating conditions. Actual room temperature and heating performance depend on building insulation, ceiling height, outdoor temperatures, air infiltration, installation location, and the overall heat loss of the space. Select the heater according to the calculated heating load and the manufacturer's installation requirements.

Finned Electric Heating Technology

The P3P5120CA1N uses brazed steel finned heating elements with a copper-clad steel sheath to transfer heat to air moving through the unit. The integrated fan draws air through the heater and across the energized elements before distributing warm air into the surrounding space. This electric resistance heating system does not require onsite fuel storage or a combustion exhaust system. The finned element design supports heat transfer to the moving air stream, while proper airflow and installation help maintain intended operating performance. Install and operate the heater according to TPI Corporation's instructions and maintain all specified clearances.

1,100 CFM Airflow & Forced-Air Heat Distribution

The TPI Corporation P3P5120CA1N provides a rated airflow of 1,100 cubic feet per minute (CFM). Its integrated fan distributes heated air into the intended space, supporting supplemental heating in applications where forced-air circulation is beneficial. The manufacturer specifies an air-throw distance of approximately 32 feet. Actual distribution depends on mounting height, installation orientation, room layout, and obstructions. The manufacturer's published mounting guidance identifies a maximum mounting height of approximately 12 feet for horizontal installation and 18 feet for vertical installation. Follow the current installation instructions when determining mounting height, direction, and clearances.

Compact Steel Enclosure & Flexible Installation

The P3P5120CA1N features an 18-gauge welded steel enclosure with a powder-coated finish designed for commercial and industrial service environments. Its approximate dimensions are 21-1/2 inches wide, 6-1/2 inches deep, and 28-11/16 inches high. The manufacturer's published specifications list an approximate unit weight of 65 lb. The heater supports ceiling or wall installation in horizontal or vertical configurations when permitted by the manufacturer's instructions. Appropriate mounting hardware, structural support, positioning, and installation clearances are essential. Have the unit installed by qualified personnel using TPI Corporation's mounting requirements and instructions.

Electrical Power & Energy Consumption

The TPI Corporation P3P5120CA1N operates on a 480 V, three-phase electrical supply and delivers 20 kW of rated heating output. The manufacturer's published specifications list a current rating of 24.7 A. The heater incorporates a 24 V control circuit for its control components. Verify the unit nameplate for the exact electrical ratings, frequency, required branch-circuit capacity, overcurrent protection, grounding, conductor sizing, and connection requirements before installation. This industrial heater requires a compatible electrical installation; do not assume that a standard household plug or receptacle is suitable. All electrical work must comply with applicable codes and the manufacturer's wiring instructions.

Thermostat, Disconnect Switch & Summer Fan Operation

The TPI Corporation P3P5120CA1N includes a thermostat, disconnect switch, contactor, and summer fan switch, according to the manufacturer's published product specifications. The thermostat supports temperature control for supplemental heating, while the summer fan switch allows fan operation for air circulation without active heating when used as directed. The integrated contactor supports switching of the heating load, and the disconnect switch provides a means of isolating the unit as specified by the manufacturer. The control circuit operates at 24 V. Confirm thermostat settings, wiring arrangements, and control compatibility against the unit's wiring diagram and installation instructions.

Warehouse, Storage & Industrial Applications

The TPI Corporation 5100 Series P3P5120CA1N is designed for supplemental electric heating in warehouses, storage rooms, workshops, manufacturing areas, and other suitable commercial or industrial spaces. Its 20 kW heating capacity, 1,100 CFM airflow, and 32-foot published air-throw distance support applications requiring overhead or wall-mounted forced-air heat distribution. The suspended installation keeps the heater off the floor and can preserve usable floor space for equipment, storage, and routine operations. Verify the required heating capacity, mounting location, electrical supply, and environmental suitability before selecting the heater for a particular facility.

Mounting & Deployment

The P3P5120CA1N is designed for fixed installation rather than routine relocation. Its ceiling- or wall-mounted configuration allows the heater to be positioned above occupied floor areas and oriented to support the intended air-distribution pattern. Horizontal or vertical mounting may be used only where permitted by the manufacturer's instructions. Observe the specified mounting heights of approximately 12 feet horizontally and 18 feet vertically, subject to the current installation documentation. Ensure that the supporting structure and mounting hardware can accommodate the unit's weight and operating requirements. Maintain the specified clearances, provide suitable electrical connections, and position the unit to allow access for inspection and service.

Safety, Service & Maintenance

The TPI Corporation P3P5120CA1N combines a welded steel enclosure, finned electric heating elements, and an integrated fan motor for forced-air heating. Its permanently lubricated fan motor reduces routine lubrication requirements. The integrated disconnect switch supports electrical isolation in accordance with the manufacturer's instructions. Inspect the enclosure, mounting hardware, wiring, electrical connections, fan assembly, thermostat, and heating elements at intervals appropriate to the operating environment. Keep the air inlet and discharge clear of dust, debris, and other obstructions to maintain airflow and reduce the risk of overheating. Disconnect and isolate the electrical supply before cleaning, inspection, or servicing, and allow the heater to cool before working on internal components. Electrical maintenance and repairs must be performed by qualified personnel using manufacturer-approved replacement parts.
