Flow Torch™ 
Flow Torch™ heaters are highly efficient and ideal for heating large airflows. Some of the advantages these process heaters offer are:
- Minimal obstruction to airflow (low pressure drop)
- Ideal for low pressure (and economical) blowers
- Support high volume air flow
- Heat air up to 482°C (900°F)
- Fast heat up and cool down due to low mass open coil design
- Can be connected to suitable flexible duct or pipe fittings
- All Flow Torch Heaters are UL recognized components under UL file number E365755.
Farnam offers a range of graduated sizes for this versatile platform, making it a standard product with multiple customizable options. Our team provides application assistance to help you select the heater that best suits your needs. Additionally, control packages, pressure drop charts for easy comparison, and regenerative blowers integrated with complete systems are all available.
