Industrial Electric Air Heater

The Industrial Electric Air Heater is a forced-air heating solution designed for agricultural, livestock and industrial building applications that require reliable temperature control without an on-site fuel combustion process. Electric resistance elements heat the passing airflow, allowing warm air to be distributed directly into a room, ventilation duct or designated heating zone.

The heater can be configured for livestock farms, pig farms, poultry houses, greenhouses, agricultural workshops, equipment rooms and other enclosed farm buildings. It can be used for primary heating, auxiliary heating, air tempering or localized temperature support depending on the building design and calculated heating demand.

In livestock equipment projects, electric air heaters can be integrated with a livestock ventilation system and environmental controller so heating demand is coordinated with fresh-air exchange. Proper system design should consider building dimensions, insulation, ventilation rate, target indoor temperature, animal production stage and local winter conditions.

SHEWUYOU provides project-oriented heater configurations for pig farm construction, poultry farm construction, steel structure building projects and integrated agricultural project applications. Heating capacity, electrical supply, airflow arrangement, installation dimensions and control configuration can be customized according to project requirements.

When electrical power is supplied, current passes through the resistance heating elements. Electrical resistance converts the supplied energy into heat, increasing the element surface temperature.

Air supplied by a fan or livestock ventilation system flows across the heating elements. Heat is transferred from the elements to the moving air, and the heated air is then distributed into the livestock house, poultry building, greenhouse or other required space.

Heater output can be controlled through staged switching or other suitable control methods according to the project configuration. Temperature sensors, thermostats and environmental controllers can be used to regulate heating demand, while airflow and over-temperature protection can help prevent operation under abnormal conditions.

System Design

Heater capacity should be selected according to airflow volume, required temperature rise, building heat loss and operating conditions. For livestock applications, heating calculations should be coordinated with minimum ventilation requirements so the livestock ventilation system can maintain suitable air quality while controlling heat loss.

Installation Position

Install the heater in the specified airflow direction and provide sufficient access for inspection and servicing. Duct dimensions, mounting flanges, airflow distribution and nearby components should be confirmed before installation. The heater should not be energized without the airflow conditions required by the selected design.

Electrical Installation

Power supply voltage, phase, cable capacity, circuit protection and grounding must match the approved heater configuration. Electrical work should be performed by qualified personnel in accordance with applicable local electrical regulations and project specifications.

Control Integration

Where the heater is connected to a fan, air-handling unit or livestock environmental controller, the control sequence should prevent heater operation when required airflow is unavailable. Temperature protection and control devices should be checked during system commissioning.

Routine Maintenance

• Disconnect and isolate the electrical supply before inspection or maintenance.
• Inspect heating elements for dust accumulation, deformation or visible damage.
• Keep air passages and surrounding duct sections clean and unobstructed.
• Check electrical terminals, contactors and wiring connections at planned service intervals.
• Inspect insulating supports and mounting points for damage or looseness.
• Check over-temperature devices and airflow safety controls during scheduled maintenance.
• Inspect connected fans and ventilation components to confirm adequate airflow.
• Increase inspection frequency in dusty, humid or corrosive agricultural environments.
