Pressure-Changed Vacuum Drying oven for dry type transformer
Safety design:
Triple vacuum leak protection (accuracy 0.1Pa/s), over temperature self cutting system (millisecond response), IP65 protection level control cabinet, certified with SIL2 functional safety.
Reliability parameters:
MTBF (Mean Time Between Failures):>10000 hours
Sealing life of the cavity: ≥ 500000 times of opening and closing
Emergency drainage: 5-second rapid emptying mechanism
Material Standard: ASME VIII Div.1 Pressure Vessel Certification
High risk scenarios:
Special working conditions such as drying of solvent containing materials (real-time monitoring of LEL concentration), dust explosion environment (nitrogen inerting system), radioactive material treatment (lead shielding optional), etc.
