Can pipe heaters be used to heat nitrogen in chemical industry and scientific research production laboratories?

Yes. Pipe heaters can heat nitrogen. Nitrogen heaters are primarily used to heat nitrogen from its initial temperature to the desired air temperature, up to 850°C. They are widely used in many research and production laboratories, including those in the aerospace, chemical industry, and universities. They are particularly suitable for automated temperature control and high-flow, high-temperature integrated system and accessory testing.

Nitrogen heaters are electric heating devices that primarily heat gas streams. The heating element is a stainless steel heating tube. Multiple baffles (guide plates) are installed within the heater cavity to guide the gas flow and extend its residence time, ensuring full and uniform heating and improving heat exchange efficiency. The stainless steel heating tube of the air heater's heating element is a seamless steel tube filled with a heating wire. The interstices are then filled with magnesium oxide powder, which has excellent thermal conductivity and insulation properties, and then reduced to form a tube. When current passes through the high-temperature resistance wire, the heat generated diffuses through the crystallized magnesium oxide powder to the surface of the heating tube, where it is then transferred to the heated air, achieving heating.

Main Functions:
a. The gas nitrogen heater is equipped with standard electrical protections, such as short-circuit protection;
b. It monitors process temperature and provides alarm outputs;
c. The gas nitrogen heater's PID parameter tuning is automatic;
d. The gas nitrogen heater has an over-temperature alarm system.
