Air Heater
Air Heater Tubular refers to a tubular-type electric heating element specifically designed for heating air or gas in ducts, chambers, or open environments. These heaters are widely used in industrial drying, heating, ventilation, and process heating systems.
Tubular air heater is made of metal-sheathed resistance wires (usually NiCr) insulated with magnesium oxide (MgO) and enclosed in a stainless steel or Incoloy tube. The heater is often mounted in a duct or airflow path, and heat is transferred to air passing over or through the element.
Types of Tubular Air Heaters1. Plain Tubular Air Heater
o For clean air applications or low air velocity
o Installed in ducts or chambers
2. Finned Tubular Air Heater
o Metal fins improve surface area and heat transfer efficiency
o Ideal for forced air or high-velocity airflow
3. Duct Heater Assembly
o Multiple tubular elements mounted on a flange or plate
o Used for HVAC systems, drying ovens, industrial blowers
