Industrial air heaters are essential heating devices designed with the ability to heat air in a controlled manner for many types of manufacturing, processing, and environmental conditioning applications. These electric heating devices convert electrical energy to thermal energy using resistance heating elements such as nichrome, kanthal, and various other types of heating element. Unlike a fluid-based heating system, industrial air heaters will achieve a faster thermal response time, heat without fluid contamination, and produce remarkable temperature uniformity, which is critical for industries in aerospace, pharmaceutical, plastics processing, and semiconductor. At Tempsens, we offer an extensive range of high temperature air heater solutions for continuous duty cycles, harsh environments, and tight process control limitations. Our electric air heater industrial series incorporate advanced materials, high quality constructions, and comply with international safety standards for dependable performance in temperatures spanning from ambient to 450°C.
About Air Heater
Air heaters use resistance components to transfer heat to air flows through convection and conduction. Designed for pressures reaching 40 bar, it is equipped with stainless steel housings, coils insulated with MgO, precise welds, and thermocouples controlled by PID to maintain stability within ±1 °C, avoiding contamination while providing reliability in harsh industrial processes. These design characteristics represent some of the important considerations before choosing an air heater.
Applications of Industrial Air Heater
- Processing of Plastics: Pre-warming air streams for injection molding, extrusion dies, and thermoforming processes that need temperature uniformity of ±5°C.
- Drying Systems: Industrial dryers for bio-drying pharmaceutical powders, food processing, textile finishing and coating curing equivalent processes.
- Manufacturing of Automotive Products: Heating of paint booths, thermal cure ovens, and climate control for assembly line conditioning.
- Wytwarzanie Energii: Turbine inlet air heating, combustion air preheating, and freeze protection for critical instrumentation.

Benefits of Industrial Air Heaters
- Fast Thermal Response: Electric air heater industrial systems achieve operational temperatures in 3-5x the speed of combustion-based systems, decreasing process time to heat, and increasing output capacity in batch process systems.
- Contaminant Free Heating: Sealed resistance elements don’t introduce combustion by-products, particulates and/or moisture, which is critical to cleanroom, food grade and pharmaceutical applications, which require cleanroom to ISO Class 5-8 environments.
- Accurate Temperature Measurement: Built in sensors and PID Controllers with +1°c setpoint accuracy, prevent thermally degrading materials such as plastic, composite and chemical processing.
- Low Maintenance Needs: Solid state heat elements have no mechanical parts, allowing maintenance to be limited to once a year and creating an overall cost of ownership with less risk of unplanned downtime.
- Scalable Heat Output: Modular design allows parallel or series constructions to handle any process thermal load from 1 KW lab new systems to 500 KW tier 1 new industrial systems.
- Corrosion Resistant: Stainless steel and Incoloy construction is able to withstand aggressive chemical vapors, excessive humidity, and corrosive atmosphere to chemical processing, and water treatment facilities.
