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.
