The WS-YDC Horizontal Cylindrical Pressure Steam Sterilizer offers advanced safety and operational features for effective sterilization. It includes automatic safety mechanisms for door locking, pressure release, and power cutoff in case of overload or leakage. The unit is constructed entirely of stainless steel for durability and hygiene.

Key Features — WS-YDC

The steam cannot go through to the chamber when the door is not closed, and the pilot light indicates this status. Dry operation is possible.
The door is locked and cannot be opened when the internal pressure exceeds 0.027MPa.
A buzzer sounds if the sterilization time is not selected before starting the machine.
If the door is mistakenly opened during operation, the jacket valve automatically shuts off and the chamber valve opens.
The lack of water indicator turns on, heating and sterilization indicators turn off, a buzzer sounds, and steam is automatically released.
If the temperature control fails and the internal pressure exceeds 0.22–0.24MPa, the safety valve automatically opens.
Fully stainless steel structure.
