Advantages Over Conventional Heaters
Designed for Medium-Pressure Operation
Conventional duct heaters are typically limited to low-pressure systems and are not engineered for safe or efficient operation at elevated pressures. The Pressure Torch™ 400 is purpose-built for medium-pressure air heating up to 150 PSI, eliminating the need for oversized housings or external pressure vessels.
Faster Thermal Response
Traditional heaters rely on high-mass elements that respond slowly to temperature changes. The low-mass open-coil design of the Pressure Torch™ 400 enables rapid heat-up and cool-down, improving temperature accuracy and reducing energy waste during cycling.
Low Pressure Drop
Many conventional air heaters restrict airflow, increasing blower load and system energy consumption. The Pressure Torch™ 400 is engineered to minimize obstruction to airflow, maintaining low pressure drop even at high flow rates. Improved Energy Efficiency By combining fast thermal response with low airflow resistance, the Pressure Torch™ 400 delivers more efficient air heating and reduces overall system energy consumption.
Rugged Industrial Construction
The stainless-steel, pressure-rated heater body and fittings provide long service life and reliable performance in demanding industrial environments where conventional heaters may fail prematurely.
Simplified Installation and Integration
Flanged stainless-steel inlet and exhaust connections, along with horizontal or vertical mounting options, simplify integration into new systems or retrofit applications.
Enhanced Safety and Control
The Pressure Torch™ 400 supports precise temperature regulation when paired with custom TUTCO Farnam control panels, providing improved process control and system protection compared to many conventional heaters.
Why Choose the Pressure Torch 400?
The Pressure Torch™ 400 delivers a balanced solution for industrial air heating—combining medium-pressure capability, high airflow, fast response, and durable construction in a compact, easy-to-integrate design.
Backed by TUTCO Farnam’s application expertise and supported by custom control solutions, the Pressure Torch™ 400 provides reliable, efficient performance across a wide range of industrial processes.
