The Smallest, Lightest, and most Affordable
Portable Electric Heaters on the Market!

Mosebach has done it again!
We’ve squeezed more heat into a smaller package - the smallest heaters of their type now available. The HotBox XtremeQ™ takes our locomotive-proven resistor design one step further - we now offer designs up to 614,000 BtuH, or 180 kW.

HotBox XtremeQ™ uses Mosebach’s unique Weldless Weave™, a continuous resistor ribbon that contains no welds. This design has been proven over dozens of years on locomotives and giant mining trucks, in models up to 5,000 kW. We have now adapted the technology for use in small, portable electric heaters.

The HotBox XtremeQ™ is ideal for heating large spaces, buildings, and machines and processes, without the problems of kerosene or propane heating, such as mold-causing moisture, fires, and carbon monoxide. Some of the other possible HotBox XtremeQ™ applications are:
• As blowers only
• Heating warehouses and tents
• Heating buildings under construction
• In heavy industries, such as steel mills, refineries, chemical processing, etc.
• In eliminating condensation, dehumidification processes and removing
   the moisture from building structures
• In pest control market

ADVANTAGES OVER THE COMPETITION:
• Unique design: three heaters in one
• Can work in fan mode only
• Variety of options to rent or to use as (fan only, 60 kW, 90 kW, 150 kW or 180
   kW electric heater)
• Option to disable each stage of heating simply by turning the circuit breakers in
   “OFF” position. Circuit breakers are tied in series with 22mm ON/OFF load    switches
• Weatherproof enclosure (ducting must be attached)
• Size, portability, weight and dimensions
• User friendly
• Heavy-duty, Mosebach’s own stainless steel heating elements with unmatchable
   5-year warranty

Heating Elements: HotBox XtremeQ™ uses our unique Weldless Weave™, the toughest resistor element available. This element allows for maximum heat transfer in the smallest space. We’re so sure of it, we offer an unmatchable 5-year warranty on resistors!

Cooling: The heating elements are cooled by an integrally-mounted, single inlet, low noise, 3-phase plenum fan.

Controls: HotBox XtremeQ™ is controlled by a combination blower-on/thermostat 22mm switch, one master red mushroom ON/OFF switch that doubles as an E-stop button and 22mm ON/OFF switches for each stage of heating. Remote thermostat with 50’ cable, an air flow indicator lamp and an overtemperature lamp are provided as well. The thermostat allows for temperature control. Two circuit breakers have been installed in series with contactors. By turning the breakers in the OFF position, the client can disable each stage of heating and rent each unit as a 60 kW, 90 kW, 150 kW or 180 kW heater or fan only. The controls are NEMA 3R and are recessed to prevent accidental damage. No additional power required.

Power Connection: Recessed, color coded cam-lock type connectors (A, B and C), 400A rated, are provided for easy and safe connection to the power source. Mating female cam-lock type connectors are provided as well.

Controls and Fuse Access:The top removable panel allows easy access to all control components and the high-quality fuses.

Construction and Maneuverability: L = 60”; W = 33”; H = 38”. HotBox XtremeQ™
is made of heavy-duty, rugged sheet metal with expanded-metal inlet and exhaust coverings. The paint finish is electrostatic powder-coated, scratch resistant - the toughest finish available. Extreme maneuverability is provided by two fixed casters and two swivel casters with stop brakes. Forklift channels and four lifting eyes are also provided for easy maneuvering and lifting. The HotBox XtremeQ™ is the smallest and lightest heater of this size available today!

Weather Rating: Each HotBox XtremeQ™ is weatherproof rated. 20” ducting must be attached.

Ducting: Hardware is provided with each HotBox XtremeQ™ (2 x 20” ducting rings with four clamps) for the customer to connect their flexible ducting.

Safety: Each heater is provided with an overtemperature switch (automatic reset). In case of low air flow, the air pressure switch will disconnect the power to the unit. Every electric circuit is protected by heavy-duty fuses and magnetic contactors. E-stop button is provided for emergency shut down. Motor is protected by fused motor starter. Ground lug and overtemperature indicator lamp are standard. All components are rated for 600V. And because the heating is electric, there is no risk of dangerous fumes, fires, or mold-causing moisture.

Options Available for Purchase:
1. Ducts: 25' or 50' or more

Warranty: The HotBox XtremeQ™ has a standard one-year warranty on workmanship and materials, and an unmatchable 5-year warranty on the resistor elements.

We also have a line of smaller heaters available – the original HotBox™, from
10/15 kW and 60 kW HotBox XtremeQ™.
