7 rack freeze dryer

Our mid-sized system, the TSS-747 is a great choice for anyone looking to expand their freeze drying operation.

329 shelf capacity, this walk-in freeze dryer is perfect for the smaller but competitive freeze drying operation.

The TSS-747, a 7-rack freeze dryer from TechSource Systems, is a versatile mid-sized system ideal for expanding freeze-drying operations. With a 329-shelf capacity, this walk-in freeze dryer suits smaller yet competitive freeze-drying setups. Mechanical features include an all-stainless-steel rib-reinforced process chamber, Leybold SP630 vacuum pump, and a low-temperature chiller (-40C to 20C). The PLC controller, powered by Opto22 GROOV technology, ensures safety with user-programmable vacuum cycles and 96 unique recipes. Independently heated shelves, precise heat input matching sublimation requirements, and three heat control zones per rolling rack enhance electrical efficiency. This advanced medium freeze-drying system emphasizes performance, control, and adaptability.

Base unit price, turn key system with all components included: $775,000
