LGJ-20Plus Laboratory Freeze Dryer

The Vekuma LGJ-20Plus freeze dryer is floor type, designed to perform lab R&D and small volume trials. It has a 22L large volume ice condenser, effective vapor collect capacity up to 9kgs.

Base Unit: Powder coated steel exterior, with wheels for easy to move. An upright stainless steel ice condenser is inbuilt, the condenser is chilled by coolant direct expand and is allowed for raw material pre-freezing. A wide range of accessories can be connected to the ice condenser to expand freeze dryer functions. Lateral of base unit has vacuum port, vacuum release valve and water drain valve. Freeze dryer power cable and vacuum pump power plug is located on rear side of base unit.

Control System: A 7” touch screen HMI is mounted on the freeze dryer base unit, it real-time displays condenser temperature, product temperature and vacuum degree. 3 large buttons on touch screen bottom are use to control compressor and vacuum pump working and condenser defrosting. Sub-pages include debugging interface of system setting and sensors calibration, real-time drying curve and data downloaded.

Drying Chamber: The drying chamber available in 6 selections, from bulk to manifold, to enable products dried in trays, vials, ampoules, flasks and other glass bottles.

Vacuum Pump: A 2-stage oil sealed rotary vane vacuum pump is included in the standard offer. Vacuum pump connects to freeze dryer by a hose and a pair of tri-clamp.
