Fuzzy-supported process controller for volume-optimized temperature control - individually for each shelf - programmable for up to 40 ramps (Multi-Level-Controlling), adapting its performance to the volume (local temperature sensing ) for each thermoshelf. Digital display of actual temperature traceable individually for each thermoshelf (Multi-Level-Overtemperature Protection MLOP), activated at 3°C above the setpoint. 7-day-program-timer with real time clock and timer (for residual time - programmable for each ramp segment). Multiple overtemperature protection, undertemperature alarm and gliding over/undertemperature monitoring linked automatically to the setpoint (ASF = Auto-Safety Function) at a preselected tolerance margin. Autodiagnostic system for rapid fault identification. Menu guidance by 8-digit alphanumerical display. Setpoints and actual temperature recording with MEMory Card XL up to 40 ramps. Ring store 1024 kB for long-term documentation of all relevant data.
Digital electronic pressure control (in program operating up to 40 ramps, settable for each segment) for vacuum control via solenoid valves. Setting range from 10 mbar to 1100 mbar. One programmable, digitally controlled inlet for air. Integrated drying process control with programmable vacuum cycles for a speeded-up moisture reduction.
Optional pump control: Optimised rinsing procedures for pump membranes as needed, as well as signal output for pumps ON/OFF (recommended with PMP).

Interface USB with software "Celsius" with advanced features for temperature and pressure. 2 connection options for thermoshelves
1 aluminum thermoshelf, anodized, material 3.3547 (ASTM B 209).
Works calibration certificate (measuring point at the center of the thermoshelf for 160°C at 50 mbar pressure); a separate certificate is prepared for each thermoshelf ordered and shipped together with the vacuum oven.

External dimensions: depth without door handle, depth of door handle 38 mm
Electrical load: with max. number of thermoshelves
All vacuum ovens according to DIN 12 880: 2007-05. Standard ovens bear the marks: EMV/VDE/GS/CE/GOST

The cooled vacuum drying oven VO200cool with 29 liters and the VO400cool with 49 liters interior volume have a temperature range of +5°C to +90°C. For cooling, a compact, energy-saving and highly precise Peltier cooling unit was integrated. Thus, the cooled Memmert vacuum drying units achieve an even temperature distribution over the entire temperature range with a maximum deviation of ±1 K.
Gentle vacuum drying and storage of microorganisms or pharmaceutical agents at low temperatures is used above all in the food and pharmaceutical industries. It allows for drying of sensitive substances at moderate temperatures above the freezing point, avoiding excessive damage to the cell structure. Furthermore, the cooled vacuum drying ovens VOcool by Memmert provide for easy, inexpensive simulation of the storage and transport of pharmaceuticals during intercontinental flights.
