Constructional Features

• Air-tight door closure with double sealed packings.
  - Heat-resistant silicone double packing completely blocks high heat leakage from the inner chamber. 
     (only for LBV Models)
  - Non-conducting ceramic and heat-resistant silicone packing completely blocks high heat leakage from the inner chamber.(only for LTV Models)
  - Two-point door latch also enhances tightness to door closure.
• Energy efficiency is achieved thanks to optimization of the insulation system.
  - Even if the unit is operating at max. temperature, the surface of the unit doesn’t allow high temperatures of over 51℃. (DIN EN 563) 
• Reliable design and production of door is guaranteed.
  - Evaluates the results after opening the door by 90 degrees and applying 50kg load to the point of 30cm from hinges.
• Corrosion resistance stainless steel inner chamber.
• Space efficient and easy loading chamber design.
  - Included two shelves for loading of large amounts of samples.
  - Heavy load shelving, rated for 40kg are also available. (optional)

Safety Features

• Over-current & Current Leakage Protection. (ELCB, Earth Leakage Circuit Breaker)
• Independent Safety Fuse.
  - Important parts such as controller and heaters are highly secured from short circuit. Especially each heater has an individual fuse to completely break a short circuit.
• Reversed-phase Protection.
  - Electrical connection error indicator helps user to rapidly fix the connection
• Over-current Protection of Motor.
  - Automatic Shut-off in situations where there is over-current to the Motor.
• Door Open Warning.
  - Heater & Fan stop when the door is the open state.
• Electric wiring panel access warning.
  - Automatic stop if the cover of electric wiring panel is opened. 

Operating Features

• Suitable for specific use such as heat treatment and drying process.
• Colorful interactive touch type LCD controller.
• Set point temperature and present temperature areclearly shown together on display.
• Sufficient programmable control support.
• Operating progress can be shown in graph mode for better data understanding.
• Automatic start/stop can be programmed for unattended operations.
• User selectable operation mode after power interruption -ether Automatic run or Manual run.
• Display indicates abnormal temperature changes or power failures.
• Three different language support. (English / Chinese / Korean)
• Temperature and other operating parameters can be recorded using a six channel digital recorder.(optional)
  
• Programming operation.
  
  

  Description	No.
  Programmable Pattern Capacity	100
  Pattern Repeat Time	999
  Part repeat time	255
  Max. Segments per a Pattern	100
  Available Max. Segments*	6000
  Programmable Process Time per a Segment	0 to 99 hr 59 min

  * Even though the max. segments per pattern are 100, the total available segments are up to 6000 not 10000, therefore arrangementof the number of segment and patterns will need to be done properly.
