Compared with the existing IR dryer, this IR dryer has a good efficiency from the minimum 50% to the maximum 200% by adopting Unitro hot-wind of the special panel type IR projection and the merit of IR. In meantime, it controls the temperature distribution very precisely, and particularly, it is very high-end model because when it dries the materials which is sensitive to the heat, it gets rid of the expansion or contraction trouble in fabric by pushing the indoor air.
