Product Information

The HI 770XHD models are very heavy duty, highly reliable, indirect fired air heaters, designed to run 24/7, in extreme environments. These units can withstand blizzard and ice storm conditions with up to 70 mph winds and will operate in temperatures to -60°F. Gone are the days of makeshift containment systems with the environmentally friendly Triple Threat™ spill containment feature which ensures that no diesel fuel, engine oil or engine coolant will contaminate the site.
