OPEN-LOOP SPOT HEATERS<\/h2>\n<\/div>

Series heaters are versatile, compact<\/strong> electric air heaters designed for spot heating<\/strong> applications. They feature Serpentine<\/strong>\u2122 heating elements housed in either a Quartz open-end (Style A) or nozzle design (Style B) <\/strong>, making them adaptable for various uses.<\/p>\n<\/div>

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

Open-Loop (Manual) Control:<\/strong> this simple <\/strong>method of control uses a manually operated power controller<\/strong> to apply a fixed voltage<\/strong> to the heating element. Using this system, the operator manually adjusts<\/strong> 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.<\/p>\n
