TPI Corporation FES-Series Portable Heater 30kW 480V 3P

Description

Stage the high-voltage TPI Corporation FES-Series 30kW Heater inside commercial enclosures to dry drywall compound and cure fresh concrete slabs without open flames. This heavy electric forced-air unit outputs 102,390 BTUs across industrial work bays. It requires a hardwired 480V 36-amp three-phase power supply, making it impossible to operate on standard 120V or 240V utility circuits.

Heavy 18-gauge cold-rolled carbon sheet steel constructs the barrel cabinet and chassis, finished in durable industrial baked enamel paint. An enclosed continuous-duty electric motor draws 36.1 full-load amps on 480V 60Hz three-phase lines, driving an internal axial fan. Net dry tool weight measures 83 lbs. The wheeled tubular steel cart spans 30 inches long, 24 inches wide, and 39 inches high on ten-inch rubber tires.

Key Features of TPI FES-3048-3A

Commercial general contractors buy TPI FES-3048-3A 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 102,390 BTUs of dry fume-free heat without carbon monoxide hazards.
• Internal high-output axial fans move 1,100 CFM of heated air deep across wide commercial floor bays.
• Heavy tubular steel roll cage carts protect internal electrical components from jobsite drops and impacts.
• Ten-inch semi-pneumatic wheels roll across frozen mud ruts, concrete expansion joints, and scattered jobsite cords.
• Built-in adjustable thermostats cycle the 30kW heating elements to hold target room temperatures.
• Automatic high-limit thermal safety 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 power lines confirms balanced current draw holding at 36.0 FLA under full 30kW demand. Discharge air temperature climbs 82 degrees Fahrenheit above ambient across the finned heating rack at 1,100 CFM air throw. Static pressure testing shows zero blower motor bog under high air resistance. Operating sound meters record 72 dB at six feet from the exhaust grille. Contactors engage with solid mechanical force and show zero contact arcing under rapid cycling tests.

Jobsite Mobility Realities Maintenance

Steering this 83 lb heater takes one worker using the tall tubular pull handle over rough concrete slabs. Electricians must wire three-phase feeder cable into the internal terminal block. Do not buy this heater for residential living spaces, single-phase 120V circuits, or flammable spray paint rooms.

• Check electrical terminal lug torque using 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 and cart frame bolts twice per year.
