• Condenser ice capture capacity approx. 6 kg/24 h; condenser temperature options down to -86°C
• Pre-freezing and drying in the same chamber; automatic and manual control modes; optional vacuum stoppering for vials
• Silicone-oil circulation heating or direct electric-heated shelves; suitable for vaccines, probiotics, polypeptides, traditional medicine, food samples and fruit
• Data export via USB; optional remote control and FD-LYO software

Overview
FD-10F Series is a compact, automatic in-situ pilot lyophilizer engineered for small-batch processing of biological and food samples. Models support silicone-oil circulating or electric shelf heating and offer optional stoppering under vacuum for vial sealing. The design prioritizes cleanability, controlled thermal transfer and precise process management for R&D and pilot production.

Chamber

• Rectangular chamber enabling pre-freezing and primary drying without sample transfer
• Chamber, shelves and trays in polished SS304; SS316 contact-parts available as option
• High-transparency plexiglass observation door and rounded internal corners for easy cleaning
• Silicone-oil circulation heating for high temperature precision (bio/medical); electric heating available for food-oriented use
• GUNDFOS shielded circulating pump and PID control for oil-heated variants; low-viscosity silicone oil as heat transfer fluid
• Electric heating shelves with safe voltage and controllable ramp rates

Condenser Chamber (cold trap)

• Large-capacity SS304 condenser (SS316 optional for corrosive processes)
• Lowest condenser temperature: up to -86°C (silicone-oil versions) or to -60°C (electric versions)
• Fast cooldown capability: e.g. +20°C to -40°C in ~30 minutes
• Independent cylinder-type cold trap with plexiglass door and strong ice removal capacity
• Patented gas diversion technology for uniform cold trapping and improved ice collection
• Optional electric defrost/heating around condenser to assist ice removal

Refrigeration

• Dual-stage cooling architecture for stable low-temperature performance
• Hermetic compressors from established brands (e.g. DANFOSS) and CFC-free refrigerant
• Danfoss pressure controllers and valves for consistent control
• Condenser capability options: typical ≤ -60°C; low-temperature option to ≤ -86°C
• Air-cooled operation without external chiller; brazed plate heat exchanger included

Circulation system

• GUNDFOS (Denmark) shielded circulation pump on silicone-oil heated models (FD-10F-R / FD-10F-TP)
• PID-controlled electric heating elements for accurate shelf temperature regulation

Control system

• Flexible manual and automatic control modes with PLC-driven logic
• Standard 7" LCD touch graphic display; Siemens PLC and 10" touchscreen optional
• Shelf temperature profile programmable; 32 programs with up to 36 segments each (curves storable and editable in real time)
• Built-in data recorder with USB export; optional FD-LYO software and remote control via PC/mobile
• Sensor calibration, real-time and historical alarm display, user-levels and password protection

Vacuum system

• Two-stage rotary vane vacuum pump included; automatic vacuum control and setpoint adjustment
• Ultimate vacuum typically down to ~1–5 Pa (model dependent); premium pump options (LEYBOLD/ULVAC)
• Designed to reach operating vacuum from atmosphere to ~10 Pa in under ~30 minutes (model dependent)
• Low system leak rate design (specification: system leak rate < 10 Pa·l/sec)

Safety protection

• Machine-level interlocks and protection logic for electrical and process safety
• Alarm functions for vacuum, temperature and critical system faults
• Power on/off and sublimation process protections; condenser–vacuum interlock

Other features

• Normal types for bulk products (food, fruit, herbal); stoppering types for vial sealing under vacuum
• Inflatable (water) valve plus safety diaphragm valve for inert gas connection and shelf-life extension
• Compliance and certificate options: CE, ISO 9001, ISO 13485, ISO 14001; configurable to GMP on request
