Series heaters are versatile, compact electric air heaters designed for spot heating applications. They feature Serpentine™ heating elements housed in either a Quartz open-end (Style A) or nozzle design (Style B) , making them adaptable for various uses.

ypically powered by open-loop (manual) controllers, these heaters are simple yet effective. The air inlet includes a durable high-temperature silicone rubber adapter, equipped with male spade power connectors and a grounding bracket for secure installation. Mounting is straightforward, whether integrating into existing equipment or new setups. Air is usually supplied through compressed lines, ensuring efficient and reliable performance.

Open-Loop (Manual) Control: this simple method of control uses a manually operated power controller to apply a fixed voltage to the heating element. Using this system, the operator manually adjusts the controller to change heater temperature. If the airflow is suddenly interrupted, the element could fail. This is a common and inexpensive controller and often used with simple single phase standard catalog products.

• Always ensure air is flowing before powering the heating element
• Slowly regulate the ramp up time using the potentiometer to control AC voltage.
