Funcionamiento
Cold trap with pre-freeze function enables in-situ freeze-drying — no separate pre-freezing equipment required. Product is frozen in situ on the shelves; primary drying (sublimation) then proceeds under high vacuum with multi-stage temperature ramp; secondary drying (desorption) removes bound water under controlled vacuum. Shelf temperature uniformity is maintained to ±1 °C; pressure regulation accuracy is ±1 Pa. The fully enclosed piston compressor (SECOP, internationally recognized environmentally friendly refrigerant) provides reliable refrigeration.
