New Product-Near space sublimation furnace

The Near space sublimation furnace is widely used for Preparation of CdTe, CdS, Sb2S3, and Sb2 (S, Se) 3 solar thin film cells based on near space sublimation (CSS) method.

Features:

1. The furnace door opening structure is divided into two independent units, front and rear. The upper and lower rows of light tubes are independently controlled for temperature. After heating is completed, the furnace can be controlled by buttons or automatically split into two halves. The tubes are exposed to room temperature, and the bottom two fans are forced to cool them.

2. There are two areas below the main furnace body, namely the electrical control section and the vacuum section. The electrical control section includes temperature control circuits and mechanical action controllers. The vacuum section includes a directly connected rotary vane mechanical vacuum pump, a digital vacuum gauge, and a positive pressure protection circuit.

3. Optional vacuum automatic balance function, after setting the value, the vacuum degree inside the chamber will remain constant.

4. Optional mass flow meter control, automatic control of intake size and intake adjustment.
