Pre-freezing functions at the same place for the drying process, thus realizing automation.

36 users' programs, each of them can control up to 40 temperature zones and memorize the freeze temperature curve.

The drying room employs a glass window with high transparency to witness the process

Accurate temperature control and smooth drying effect by the circulating medium of silicone oil.

The tray possesses the freezing function, eliminating the process of pre-freezing the sample and automatically starting the drying process afterward.

The temperature of the tray is adjustable and controllable to fit into the pilot and industrial production.

Efficient protection for the vacuum pump, starting after reaching the pre-set temperature.

Digital PLC touch screen, recording the temperature of cold trap and sample as well as the vacuum degree, whose data can be exported.

Excellent capability of vapor capturing and outstandingly short drying time as a result of the separate structure of the drying chamber and cold trap.
