Large Scale Vacuum Freeze Dryer LLFD-B11 is rectangular type, cylindrical compact structure. It offers manual and auto control mode, sensor calibration, intelligent temperature control, freeze drying termination reminding and other functions. The temperature ranges from -50℃ to +70℃ and offers 3+1 layers of shelf with 70 mm if shelf spacing and size of each shelf is 270 mm × 400 mm. Material used AISI 304 stainless steel, top and bottom plate thickness 5 mm. Features CFC Free refrigerant and PT-100 platinum resistance temperature sensor. Designed with refrigeration system, shelf, condenser, vacuum system and liquid circulation system. The heat is transferred to the inner space of the vacuum chamber and absorbed heat during sublimation efficiently. The product is dried completely and evenly.

The TLFD is the largest freeze dryer with all the features and advantages of our smaller freeze dryers, but on a production scale, enabling large scale, controllable freeze drying of bulk samples in a single cycle. Featuring the very latest technology in operator control, the TLFD series has user friendly interface which allows freeze drying 'recipes' to be pre-programmed and stored, giving the end user both flexibility and confidence in the control and monitoring of the entire freeze drying process.
The Bench-top Series boasts a 3-4 kg per 24 hour condensing rate. For water based samples, -55°C condenser is the perfect choice. For samples containing solvents or with low eutectic points, -80°C condenser provides maximum performance. Designed for maximum flexibility and performance, Benchtop Freeze dryers can be customized with a range of accessories to support the needs of Laboratories and Research/Product Development teams.
Floor model freeze dryer is a compact console with casters that make it easy to move.
With the introduction of the pilot freeze dryers, we have established the connecting factor between a typical bench-top freeze dryer used in laboratories and the industrial large scale freeze dryers.
