Airflow matching is critical when designing a solar air heater. Our controller uses a thermistor to constantly monitor inside panel temperature.

Our solar air heater programmable circuit design enables preset temperature settings. Multiple temperature set way points enable the fan to either ramp up or down depending on your inside panel temperature.

Examples: If a cloud passes between the sun and the panel, the temperature drops. The fan will automatically ramp down. If it’s a hazy day, one of the preset temperatures will control CFM output to accommodate the panel temperature. A bright sunny day, the fan will ramp up to full CFM output.

True match airflow based on panel temperature ensures maximum efficiency.

Factory set to your specification at no charge. Our solar air heater fan systems are programmable circuit design with multiple preset temperature settings. Factory set to your specification at no charge.
