VO500

Vacuum oven VO500

Standard delivery Vacuum oven

The direct contact between the load and the heatable and removable thermoshelves in the chamber of the Memmert vacuum oven ensures rapid and uniform temperature control of food, cosmetics, watches, books, PCBs or injection moulds, without the loss of heat.

On this page, you can find all the essential technical data on our vacuum drying oven. Our customer relations team will be pleased to help if you want further information. If you should require a customised special solution, please contact our technical specialists at myAtmoSAFE@memmert.com.

Vacuum digital electronic pressure control through solenoid valves
Vacuum setting accuracy 1 mbar
Vacuum adjustment range from 5 mbar to 1100 mbar - digital (LED)
Vacuum rapid air intake for door opening (door is blocked under vacuum ) - programme reactivation at stored values
Vacuum vacuum drying process (vacuum cycles) is continued after power failure
Vacuum one programmable, digitally controlled inlet for air
Controller digital display of all set parameters, such as temperature, weekdays, time, pressure, programe status and set-up values
Controller separate LED-symbol for each thermoshelf in operation
Controller digital display of actual temperature for each thermoshelf individually
Timer digital 7-day programme timer with real time clock, precise minute setting, for one set value or start of ramp operation
Timer 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

Control technology

Calibration three freely selectable temperature and pressure values

Communication

Interface USB-interface incl. Memmert software "Celsius" for programming and documentation of temperature and pressure
Documentation integrated ring memory as data logger for GLP-conforming long-term documentation of all relevant parameters - 1024 kB
Documentation programme stored in case of power failure
Programming chip-card control incl. 1 MEMoryCard XL with 32 kB storage capacity (max. 40 ramps)
Programming multifunctional programming via menu on 8-digit alphanumeric digital display (language to be chosen via set-up)

Safety

Temperature control additional digitally adjustable, electronic micro-processor overtemperature monitor TWW, protection class 3.1 - (max-value for overtemperature, min-value for undertemperature)
Temperature control 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
Temperature control mechanical temperature limiter TB, protection class 1 according to DIN 12880 to switch off the heating approx. 20°C above nominal temperature
AutoSAFETY 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
Autodiagnostic system for fault analysis

Heating concept

fuzzy-supported MLC (Multi-Level-Controlling) microprocessor controller adapting its performance to the volume (local temperature sensing) for each thermoshelf
2 connections for thermoshelves in the rear (1st and 3rd level)
