process air Heaters
Process air heaters are robust hot air components used in industrial and commercial processes. Each heater is designed to work within a range of airflows and air pressures. Generally speaking, Heat Torches are low-flow high-pressure air heaters. Flow Torches are high-flow low-pressure air heaters. Applications include drying, curing, melting, cutting, baking, heat shrinking, de-soldering, metallization, heat staking, sterilization, air scrubbing, laminating, adhesive activation, hot air curtains, and air knives.
Tutco-Farnam has designed over 2,000 different custom air heaters used in factories and OEM equipment around the world. Durability, long life, rapid response time, and efficient heat transfer are goals of the heater design engineer. Our line of pre-designed process air heating solutions evolved from our custom design experience. Over time, we found that some solutions were easily adaptable to a variety of heating applications. Pre-designed solutions are customizable and made to order, so they may not be available for next-day delivery.

Pressure Flow Torch Inline Coil Heaters
Pressure 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 medium pressure (up to 150PSI) blowers
- Support high volume air flow (up to 2000SCFM)
- Heat air up to 482°C (900°F)
- Fast heat up and cool down due to low mass open coil design
- Connected via flange fittings
Farnam has developed three graduated sizes of this platform as an evolution of our popular Flow Torch product line. This family of heaters is offered as a standard product with several wattage and voltage options. Farnam offers application assistance so you can best match the heater to your requirements and needs. Control packages are available and encouraged for these heaters. Pressure Drop Charts are available for quick comparison. Regenerative Blowers available with complete systems.

Custom Specialty Heaters
If a standard threaded inline air heater solution is not suitable for your application we can provide a custom inline solution to meet your high temperature or high pressure needs.
Specialty Flanged Inline (SFI) inline heaters offer superior performance over conventional sheathed (“tubular” or “immersion”) style heaters because they are designed specifically for air and inert gas applications. Our proprietary SERPENTINE™ technology facilitates a very high power density and compact overall design. SFI heaters can be as much as 8-12X smaller than equivalent tubular/immersion designs. With this advantage, installations become smaller, lighter, and more cost effective, with a faster heat-up and cool-down time. Whether for a research test stand, factory production line, or key component in a product or system, our Specialty Flanged Inline heater is the right heater solution for the job.
Inline Duct Heaters provide ultra-compact, fast response heating for a multitude of industrial and research applications where gas pressure is ≤ 10 PSI (.7 Bar) and temperatures up to 1475°F (800 °C)
Heat Torch™ Air Heaters
Tutco-Farnam has been manufacturing high-quality inline heaters for over two decades. Tens of thousands of these devices have been built for many Fortune 1000 companies on a custom order basis. Based on this experience and increased demand, we created a family of Heat Torch™ process heaters which can be modularly assembled from a set of components to provide the best of both standardization and flexibility.
Farnam Heat Torch™ inline air heaters are ideal for rapidly heating compressed air or any non-combustible gas. Industrial strength open coil heating elements provide efficient heat transfer through direct contact with high-pressure airflow. Rapid heater response time enables precise output temperature control when these heaters are paired with off the shelf sensors and controllers. Robust design, high-quality materials, and workmanship provide long life and performance margin. We provide pressure testing for any of our Heat Torch™ products as an add-on service.
Cool Touch™ Air Heaters
Our highly efficient Cool Touch™ heat torch option minimizes the skin temperature of the heater and helps protect people and products from hot surfaces. This very efficient design reduces heat losses.
The large thermal storage capacity is particularly useful if you have an application requiring intermittent use and rapid response. This Cool Touch™ option is available for a variety of our Heat Torch sizes. We provide pressure testing for any of our Cool Touch™ products as an add-on service.
