A duct heater is an industrial device used to heat air within ducts. Its core function is to raise the air temperature from the initial level to the desired temperature (up to 850°C), making it widely applicable in aerospace, chemical production, material drying, and other fields.
Core Structure and Function
It utilizes stainless steel heating tubes as the heating element, with externally wound corrugated stainless steel strips to enhance heat dissipation efficiency. Built-in thermostats and fuses provide dual safety protection. Designed with low air resistance and uniform heating, it supports rapid and precise temperature adjustment (heating rate of 10°C per second) and includes over-temperature protection and differential pressure monitoring.
Application Scenarios
Primarily used in industrial ducts, air conditioning systems, material drying, and chemical production, covering low-temperature (≤160°C), medium-temperature (≤260°C), and high-temperature (≤500°C) requirements. Some models support remote control via mobile apps, allowing users to record usage habits and receive automated reminders.
