4.5 Million BTU Direct Fired Gas Heater

Model: HR4500
Very large industrial and construction projects request 4,500,000 BTU direct-fired heaters. These temporary makeup air heaters use high CFM and static pressure to move heat throughout the building or data center campus. The unique power management system regulates the supply voltage and will raise or lower the voltage as needed. Construction projects have fluctuating voltage with all the demand on temporary power, but the power management system helps prevent unwanted shutdowns of the heater. These direct-fired heaters operate on either natural gas or propane. Because of the high demand on fuel, vaporizers are normally specified when operating on propane.
