HOMEProductsDrying OvenDT300/300H
Laboratory Clean Ovens, Class100 / Compact type

DT300 with N2 gas injection unit and Stand (with caster) / DT300H with N2 gas injection unit and Exhaust valve (manual)

  • DT300 can maintain the cleanliness class 100 when the temperature is stable at 300deg.C.
  • DT300H can maintain the cleanliness class 100 in all heating conditions (stable, increase, decrease).
  • Equipped with various functions, including program operation (Max.99 steps, 99 patterns, repeat operation) is available.
  • Safety measures are enriched, including self-diagnosis function and an independent overheating prevention device.

High-performance type (Model:DT300H), which prevent the production of fine dust when the working temp. is stable, as well as when the temperature is going up or down.
