Dr Infrared Heater DR-P3200 20KW Three-Phase Unit Heater
Features include single or three-phase operation with 208 to 480-volt support, uniform air distribution that fills large rooms, and an overheat-protected motor designed for heavy-duty performance. The unit’s design aims to deliver steady heat with minimal turbulence, making it a practical choice for warehouses, factories, and large garages.
Dr Infrared Heater DR-P350, 5KW Three-Phase
Designed for flexibility with single or three-phase operation and a voltage range from 208 to 480 volts. It provides uniform air distribution to heat large areas efficiently and features an overload-protected, permanently lubricated, totally enclosed motor with heavy-duty bearings for durability in industrial settings.
Global Industrial Steel Unit Heater
This unit offers large, dynamically balanced fan blades for maximum airflow with minimal noise and turbulence. Adjustable louvers control throw direction, and side vents help keep the motor cool to prevent overheating. It provides up to 17,000 BTU or 5,000 watts of heat, suitable for mid-sized spaces requiring steady, economical warmth.
U.S. Solid 25 KW Induction Heater Furnace (Three Phase, 480V)
Employing MOSFET and IGBT power devices with advanced inverter technology, this induction heater furnaces deliver high efficiency, reliability, and continuous operation for 24 hours under full load. It emphasizes energy savings and elevated output power, making it a strong fit for industrial heating tasks that demand rapid, consistent performance.
TPI P3P5110CA1N 10 kW 480V Unit Heater
Built for industrial environments, this heater emphasizes high-quality construction and robust resistance to wear and corrosion. It delivers efficient air flow with even heat distribution, supporting reliable operation in demanding spaces and aligning with typical commercial HVAC expectations for 480-volt systems.
Buying Guide
Key purchase considerations for 480-volt heaters include heat output, space coverage, and electrical compatibility. For large areas, prioritize higher kW ratings and unit heaters with uniform air distribution to reduce cold spots. Check voltage flexibility (208–480V) if you anticipate voltage fluctuations or multi-site deployment. Durability features such as permanently lubricated motors, heavy-duty bearings, and enclosed housings improve long-term reliability in industrial environments.
Installation and maintenance considerations also matter. Units with easy access to the motor and fan assembly simplify routine checks and service. Louvers and adjustable vents provide control over heat direction, which helps align heat output with room layout. Noise levels are another concern in semi-quiet settings; units designed for low turbulence and balanced fans are preferable in offices or showrooms.
Induction heaters, like the 25 kW U.S. Solid model, can offer highly efficient operations with rapid heat response, but typically require specialized installation and power conditioning. Infrared-based 480V models deliver direct radiant heat, which can be advantageous for spot heating and less air disturbance in certain spaces. When comparing options, weigh initial cost against ongoing energy usage and expected lifespan to determine the best total cost of ownership.
Safety and compliance are essential. Ensure units have overheat protection, appropriate enclosure ratings, and clear installation instructions. If possible, consult a licensed electrician or HVAC specialist to verify electrical compatibility, wiring, and circuit protection for your facility’s 480V supply.
