• Roughness ≤ 0.6μm of inner wall of dry chamber and shelves,  flatness of shelves ≤ ±0.5mm / m to ensure best drying performance.
• Shelf temperature  between -50°C to +70°C ±1°C (when it balance), Fast cooling from +20℃ to -40℃ within 60 min.
• Oil circulation heating type with high temperature precision control, usually suitable for medical, bio field, electric heating type suitable for food field.
• Shelves heating system uses safe voltage, while heating rate controllable, shelf made of mirror polish stainless steel, each shelf should be tested their roughness and flatness by professional tester in order to provide uniformity temperature for sample.
• Wall-cross type is optional to meets with GMP standard.

CONDENSER (COLD TRAP)

• Large capacity condenser design, made by SS304 material, SS316 is optional for the material which has high corrosivity.
• Lowest condenser temperature reach up to -86°C for silicone oil machine, -60°C for electric heating machine.
• Fast cooling from +20℃ to -40℃ within 30 min.
• Independent Cylinder-type cold trap (FD-20F, FD-30F-TP, FD-50F-TP, FD-100F, FD-200), with high transmittance plexiglass door, powerful ice remove capacity to ensure best performance. Cooling pipe condenser for FD-10F, FD-30F-RE, FD-50F-RE, FD-50F-R model.
• Patented gas diversion technology, cold trapping ice even, ice-catching ability.
• Electric heating around the condenser chamber to remove ice effective.

CIRCULATION SYSTEM

• GUNDFOS (Denmark brand) shielded circulating pump and PID control electric heating component; circulation liquid used Low-temperature low- viscosity silicone oil.
• Circulation system is for FD-20F, FD-30F-TP, FD-50F, FD-100F, FD-200F series.

FD-LYO CONTROL SYSTEM
