This Telstar Pfeiffer Vacuu Dryer is a used freeze dryer — also known as a lyophilizer — built in 2016 and currently located in Barneveld, Netherlands. Freeze dryers are used to remove moisture from heat-sensitive materials through a process of freezing the product and then reducing the surrounding pressure to allow the frozen water to sublimate directly from solid to vapour. Telstar is a well-established manufacturer of freeze-drying and pharmaceutical processing equipment, serving industries including pharmaceuticals, biotechnology, and food technology. Pfeiffer Vacuum is a recognised name in vacuum technology, known for producing high-performance vacuum pumps and systems used in laboratory and industrial applications.
This unit carries the internal designation DUO 10M, serial number 3392, and is constructed from stainless steel grades 1.4401 and 1.4404 (both equivalent to AISI 316 and 316L respectively), making it suitable for hygienic and corrosive-resistant applications. The freeze-drying surface area is 0.48 m², and the plate diameter is 300 mm, though the plates are noted as not included with the sale. The ice condenser has a capacity of 22 kg and reaches a final condenser temperature of -55 °C, providing the deep cold necessary for effective sublimation of ice from the product.
The machine is equipped with a single cooling compressor using R-507a as the refrigerant medium, delivering a nitrogen pumping speed of up to 12 m³/h. Total installed power is 3.2 kW, with the vacuum motor rated at 0.45 kW and compatible with both 100–110 V and 200–230 V supplies. The unit includes a switch and has a compact footprint of 0.7 × 0.76 m with a total height of 1.1 m. The base unit weighs 190 kg.
