Energy-efficient Hopper Dryer - SEHD

The SEHD energy-efficient hopper dryer can be used for drying most non-hygroscopic materials, such as PS, PP, ABS, etc. The maximum drying temperature can reach 160℃ and it also can choose the optional double-layer insulation model to obtain uniform hopper temperature with less heat losses. Besides, multiple components are available as options that can recycle the hot air and filter the iron impurities in the material, which also can be installed on the ground with the floor stand. 


Optimal structure
  • Down-blowing structure design reduces the different between inlet air temperature and heater temperature to ensure stable inlet air temperature. 
  • Adopt heat-insulated blower to prolong blower lifespan.  
  • The heating tank adopts double-layer insulation structure which not only can reduce the power consumption but also can avoid too high of the ambient temperature. 
  • All material contact surfaces are made of stainless steel to eliminate material contamination.
  • Hopper separated from its base with cleaning door (except SEHD-12&25) for easy cleanliness. 

User-friendly design 

  • SEHD-25-150 pipe heater with lead sheet connected and all series are equipped with the temperature protector as to prevent the pipe heater from dry burning. 
  • With overheat release function, when the drying temperature exceeds the set deviation value, the main power supply will be automatically cut off. 
  • All series are standard equipped with the one-week timer and intermittent operation function. 
  • All series are equipped with microcomputer control and RS485 communication interface. 
  • The max. drying temperature can reach 160℃.

Energy efficient

  • Compared with the test of standard SHD hopper dryer, the drying effect of SEHD increased by 60% on average, while the power consumption decreased by 40%.
