Heaters deliver clean, dry heat in extreme conditions
The Arctic Bear HD indirect-fired heater is designed to deliver clean, dry heat in extreme conditions. It can run 24/7 and features a 100-percent stainless-steel firebox and heat exchanger. In addition to rugged construction, the unit includes an exclusive five-year Rust-Thru/Burn-Thru Warranty on both the firebox and heat exchanger.
The Arctic Bear HD’s heat output of 430,000 to 770,000 BTU/hr varies with outdoor ambient air temperature (i.e., colder outdoor air temperatures are countered by higher BTU outputs to keep the outlet temperature at a thermostatically controlled constant 210 degrees Fahrenheit). Maximum temperature rise of 240 degrees Fahrenheit is 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 (double the cfm of competitive heaters), at an impressive 4.0 inches water column static pressure (four times better than competitive units).
Three fuel options are available – diesel, natural gas, or propane.
