HSWG Features

Efficiency of HSWG heat treatment oven

Energy consumption

  • Compared to hot air dryer, the energy consumption of the radiant wave dryer is reduced by 29.39%

Dry quality

  • When drying performance was confirmed by comparing the moisture content of samples, the radiant wave dryer showed 10.7% better performance
  • In far-infrared efficiency measurement, the emissivity (5~20㎛) is 0.91, and radiant energy (W/㎡) is 3.672x, which is excellent.

Annual greenhouse gas emissions

  • GHG emissions of radiant wave dryers are reduced by 34.04% compared to hot air dryers

·Infrared ray penetration dry target
Internal temperature of drying room
· High temperature
· Heats the outside of an object to be dried with high-temperature hot air
· High temperature
· The surface temperature of the heater heating plate (400℃) heats the air inside the dry room.
·Low temperature
·The HS module does not heat the air inside the dry room
Heat loss
 · Loss of heat transfer through the interior, walls, ceiling, and floor of dry room
· Loss due to absorption inside the dry room, walls, ceiling, and floor
· Little or no loss
Energy saving effect
 · The larger the size, the higher the energy loss
· Energy saving effect is satisfactory up to 0.7m between an object to be dried and the infrared heating plate
