Manufacturer: Flagro USA
Models: HCI-600D • HCI-600D (Bulk Tank) • HCI-600G (Dual Fuel)
The Flagro 600K Indirect Fired Heater delivers powerful, clean, and dependable heat for large-scale temporary HVAC applications. With 550,000 BTU/hr output and 5,200 CFM airflow, this heater is engineered to support construction, industrial facilities, event structures, and emergency response environments—while ensuring clean, fume-free heat by keeping all combustion byproducts outside the conditioned space.
Available in diesel, diesel bulk tank, or dual-fuel LP/NG options, the HCI-600 series offers flexibility for any jobsite’s fuel requirements. A stainless-steel heat exchanger, backward-incline blower, and rugged frame ensure reliable and efficient operation in harsh winter conditions.
