Short Wave Infrared Heaters

Overview: Short wave infrared heaters operate at wavelengths of 0.78–1.4 μm, with filament
temperatures around 2500 K (2227°C). Using quartz bulbs or halogen lamps, they deliver
high-intensity heat (up to 100 W/in or 4 W/mm) and are known for their fast response times,
heating up and cooling down in seconds. This makes them ideal for applications requiring
instant heat, such as in clean-room or vacuum environments.

Design Features:
● Quartz tube or halogen lamp with tungsten filament
● Gold or ceramic reflectors for focused radiation
● Compact design with high power density

Applications:
● PET preform heating in stretch blow molding
● Drying paints, inks, and adhesives in automotive and printing industries
● Thermoforming plastic sheets
● Semiconductor processing in clean rooms

Benefits:
● Rapid heat-up and cool-down cycles
● Energy-efficient due to direct radiation
● Dust-free operation for sensitive environments
● High penetration for deep material heating
Technical Insight: Short wave heaters emit high-energy radiation that penetrates deeper into
materials, making them suitable for thick or multi-layered substrates. Their efficiency can reach
up to 90% in well-designed systems.
