The Patriot AFX indirect-fired heating system is designed as a space heater for open-area buildings. According to the company, the heater attains uniform building temperature with maximum heating efficiency using the principle of low-velocity, constant air circulation to heat large air volumes to lower temperatures. The heating system circulates the building's air volume several times each hour, developing a gentle air rotation pattern, without requiring a duct system, says the company. According to the company, the air circulation sweeps warmer ceiling air down to the comfort level, thereby minimizing stratification. It is a suspended, automatic high-volume heater and ranges from 3,850 to 10,000 scfm and from 215 to 400 MBtuh, says the company. The heating system is designed to offer humidity control, too.
