Performance

Suitable for specific use such as heat treatment and drying process.
Microprocessor PID control / Temperature calibration / Automatic tuning.
Air-tight door closure with double sealed packing.
- Heat-resistant silicone double packing completely blocks high heat leakage from the inner chamber. (for LBV)
- Non-conducting ceramic and heat-resistant silicone packing completely blocks high heat leakage from the inner chamber. (for LTV)
- 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.

Safety

User selectable operation mode after power interruption
- ether Automatic run or Manual run.
Over-temperature protection.
Over-current and 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.
Open door warning.
- Heater and 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.
Built in door lock with a key

Description	No
Programmable pattern capacity	100
Pattern repeat time	999
Part repeat time	255
Max. segments per a pattern	100
Available max. segments*	2000
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 arrangement of the number of segment and patterns will need to be done properly.
