Pipe heater two heating methods

Method 1: Direct Heating (Internal Heating)

Direct heating involves inserting a flanged tubular heating element inside the pipe heater upside down into the reactor jacket within the pipe heater to heat the thermal oil, transferring heat energy from the pipe heater to the chemical raw materials in the reactor within the pipe heater. Alternatively, the tubular heating element can be directly inserted into the reactor within the pipe heater, or heating tubes can be evenly distributed around the pipe heater's walls. This method is called internal heating. Internal heating offers rapid temperature rise and high efficiency.

Method 2: Indirect Heating (Far-Infrared Heating)

Indirect heating has emerged in recent years. It utilizes a far-infrared electric heating device, which covers the bottom of the reactor and the middle and lower sections of the reactor. Direct contact heating is not required. The far-infrared electric heating system within the reactor boasts a large internal heating area, ensuring a steady and rapid temperature increase. Heat release is uniform, and the heater is easily controlled. The heater can be controlled in sections, with upper, middle, and lower sections. The reactor wall temperature is easily controlled, and the heater has no adverse effects on the reactor contents, nor does it cause carbonization, as is the case with lined reactors. The heater operates silently and pollution-free, is durable, and offers significant energy savings.

Far-infrared pipe heaters absorb far-infrared radiation energy simultaneously at a certain depth within the heater and on its surface. Like solar energy, the heater absorbs energy and generates heat, heating the material within the pipe. Heat is distributed evenly, preventing variations in the heat volume due to varying degrees of thermal expansion. This ensures that the shape, physical and mechanical properties, fastness, and color of the heated object remain intact. Pipe heaters are widely used in electronics, electrical appliances, textiles, energy, and other fields. Far-infrared electric pipe heaters offer excellent radiation effects, energy savings, and are easy and flexible to use.
