Real-time/weekly programmer with group function (e.g. Monday – Friday). Timer with residual running time: max. 40 ramps (each 1 min. up to 999 h) programmable through controller

or MEMoryCard XL; programming via PC and free-of-charge software: unlimited number of ramps

Integrated timer for tempering and pressure (vacum) profiles of up to 40 ramps, parameters time, pressure and temperature (setpoint dependent) individually adjustable for each segment from 1 min. up to 99 hrs

Digital display of all set parameters, such as temperature, weekdays, time, pressure, programe status and set-up values

Separate LED-symbol for each thermoshelf in operation

Digital display of actual temperature for each thermoshelf individually

Resolution of display for setpoint values 0.1°C up to 99.9°C, 0.5°C from 100°C

Resolution of display for actual values 0.1°C up to 99.9°C, 0.5°C from 100°C

Calibration facility through controller for three freely selectable temperature and pressure values

Integrated ring memory as data logger for GLP-conforming long-term documentation of all relevant parameters - 1024 kB

Programme stored in case of power failure

USB-interface incl. Memmert software "Celsius" for programming and documentation of temperature and pressure

Setting of language for dialogue and display D / UK / E / F / I

Vacuum connection with small flange DN16, and gas inlet with small flange DN 16

works calibration certificate for +160°C at 20 mbar pressure for each additionally supplied thermoshelf together with the vacuum oven

Vacuum control: digital electronic pressure control through solenoid valves

Adjustment range from 10 mbar to 1100 mbar - digital (LED)

Setting accuracy 1 mbar

Digital display of actual pressure from 5 mbar up to 1100 mbar

One programmable, digitally controlled inlet for air

Rapid air intake for door opening (door is blocked under vacuum ) - programme reactivation at stored values

Vacuum drying process (vacuum cycles) is continued after power failure

Permitted final vacuum: 0.01 mbar

Maximum leakage rate: 0.01 bar/h

Additional digitally adjustable, electronic micro-processor overtemperature monitor TWW, protection class 3.1 - (max-value for overtemperature, min-value for undertemperature)

Additionally integrated over- and undertemperature protection "ASF", automatically following the setpoint value at a preset tolerance range, alarm in case of over- or undertemperature, heating of the individual shelf is switched off in case of overtemperature

Automatic overtemperature protection for each thermoshelf following the setpoint-value (MLOP - Multi-Level-Overtemperature-Protection) switching the heating of the shelf off at about 3°C above setpoint value

Mechanical temperature limiter TB, protection class 1 according to DIN 12880 to switch off the heating approx. 20°C above nominal temperature

100% safety for air (100% AtmoSAFE)

Full-sight glass door, inside spring-loaded, 15 mm thick glazed panel in safety glass, outside with anti-splitter screen

Rear zinc-plated steel

Hermetically welded stainless steel interior of extremely corrosion-resistant stainless steel, material 1.4404

Additional interior mountings of stainless steel, material 1.4404 (removable for cleaning), consisting of mounting at the sides with guide bars for thermoshelves and on top (diffusor) to avoid turbulences when aerating

All tubings made of stainless steel, material no. 1.4571
