Heavy-Duty Heater

Ground Heaters’ Arctic Bear XHD indirectfired heater provides heat output of 430,000 to 770,000 Btu/h, varying with outdoor ambient air temperature (colder outdoor air temperatures are countered by higher Btu outputs to keep the outlet temperature a thermostatically controlled constant 210°F). The unit’s maximum temperature rise of 240°F is claimed to be the highest in the industry. Airflow rates vary with ambient air temperature and duct type diameter and length. The 3-hp, backward inclined, electric-powered centrifugal blower typically operates in the 3,300 to 4,000 cfm range, at 4 in. water column static pressure. The Arctic Bear XHD is powered by a CSA certified, 10 KVA, 240 volt AC, 3-phase generator. The generator is driven by a Kubota D1105 1,800 rpm diesel engine. The D1105 engine block is mated to a specially built 20-gallon oil sump with two oil filters, allowing the generator to run 3,000 hours between oil changes. The Arctic Bear XHD has a 256- gallon diesel fuel tank, resulting in a continuous runtime rating of 40 to 64 hours. A standard fluid-spill containment system eliminates time and money potentially spent cleaning up environmentally sensitive work locations. Other standard features on the Arctic Bear XHD include crane lift eyes and forklift pockets for maximum jobsite maneuverability. A roll-up door allows for easy access to all operator controls and provides superior performance in windy conditions. The door also locks for security purposes.
