TPI Corporation FES-Series Portable Heater 15kW 480V 3P

Description

Feel dry, fume-free thermal energy warm your enclosed jobsite when you power on the TPI Corporation 15kW 480V Heater during winter drywall work. This heavy electric forced-air cart generates 51,195 BTUs without combustion fumes. It draws 18 amps on 480V three-phase power, requiring a hardwired commercial disconnect switch that residential power outlets cannot run.

Heavy 18-gauge cold-rolled carbon sheet steel constructs the barrel cabinet and chassis, finished in baked yellow industrial powder paint. An enclosed continuous-duty electric motor draws 18.1 full-load amps on 480V 60Hz three-phase power lines, turning an internal axial fan. Net dry tool weight measures 56 lbs. The tubular steel cart frame spans 28 inches long, 24 inches wide, and 39 inches high on ten-inch rubber wheels.

Key Features of TPI FES-1548-3A

Commercial general contractors buy TPI FES-1548-3A heaters to warm enclosed construction spaces without open flame permits or moisture condensation. Equipment pricing reflects heavy three-phase industrial contactors engineered for round-the-clock site heating.

• Finned stainless steel tubular heating elements produce 51,195 BTUs of dry fume-free heat without carbon monoxide hazards.
• Internal axial blower fans push 800 CFM of heated air across wide commercial floor areas.
• Heavy tubular steel cart frames protect electrical components against drops, impacts, and tip-overs.
• Ten-inch semi-pneumatic rubber wheels roll across frozen mud ruts, concrete expansion joints, and scattered jobsite cords.
• Built-in adjustable thermostats cycle the 15kW heating elements to hold target room temperatures.
• Automatic high-limit thermal cutouts disconnect power contactors if air intake vents experience sudden blockage.
• Magnetic contactors handle high 480V three-phase amperage loads without contact point arcing or switch chatter.

Electrical Load Heat Bench Metrics

Electrical bench testing across 480V three-phase lines shows balanced current draw holding at 18.0 FLA under full 15kW heating loads. Airflow velocity measures 1,120 feet per minute at the front nozzle grille, moving 800 CFM of heated air. Air temperature rises 58 degrees Fahrenheit across the finned element bank. Operating sound meters register 67 dB six feet from the fan face. Magnetic contactors snap shut with solid mechanical force and show zero contact bounce under rapid thermal cycling tests.

Jobsite Handling Realities Maintenance

Moving this 56 lb heater takes one worker using the tall tubular pull handle over jobsite slabs. Qualified electricians must wire three-phase feeder cable into the internal terminal block lugs. Do not buy this heater for residential garages, single-phase 120V circuits, or flammable spray paint booths.

• Check electrical terminal lug torque with an insulated wrench every two months.
• Blow drywall dust and mortar grit off the finned elements each month.
• Inspect the semi-pneumatic wheel cotter pins for bend wear twice each year.
