Vacuum Oven VO 500
20 °C to 200 °C.
w x h x d: 710 x 760 x 550 mm See the controller here! Standard equipment
Control
- fuzzy-supported MLC (Multi-Level-Controlling) microprocessor controller adapting its performance to the volume (local temperature sensing) for each thermoshelf
- temperature measured through 4-wire Pt100 individually for each thermoshelf
- autodiagnostic system with fault indication
- digital 7-day-programme-timer with real time clock, precise minute setting, for one set value or start of ramp operation
- integrated timer for tempering and pressure (vacuum) profiles of up to 40 ramps, each segment adjustable from 1 min up to 999 hours
- multifunctional programming via menu on 8-digit alphanumeric digital display (language to be chosen via set-up)
- digital display (LED) of all set parameters, such as temperature, weekdays, time, pressure, programme status and set-up values
- separate LED symbol for each thermoshelf in operation
- actual temperature of each thermoshelf to be made visible separately on digital display
- resolution of display for set value 0,1 °C below 99,9 °C, 0,5 °C above 100 °C; for actual value 0,1 °C
- long-term logging (ring store) of all relevant data, GLP-conforming as data logger - 1024 kB
- parallel printer interface (incl. real-time clock with date function) for all PCL3-compatible ink-jet printers for GLP-conforming documentation
- serial interface RS 232 including MEMMERT Software "Celsius 2007" for control and documentation of temperature and pressure
- chip card control incl. one MEMoryCard XL with 32 kB (up to 40 ramps)
Vacuum Control
- digital electronic vacuum control through solenoid valves
- adjustment range from 10 to 1100 mbar digital (LED)
- resolution 1 mbar
- digital display of actual pressure from 5 mbar up to 1100 mbar
- two programmable, digitally controlled connections for air and inert gas
- rapid air intake for door opening (door blocked under vacuum) - programme reactivation at stored values
- vacuum drying process (vacuum cycles) is being continued after power failure
- signal for Memmert pump module (ON, OFF/purging)
- works calibration certificate for +160 °C at 50 mbar pressure for each thermoshelf supplied with vacuum oven
Multiple Overtemperature Protection
- with audible and visual alarm
- digitally adjustable, electronic microprocessor overtemperature controller TWW maximum value for overtemperature, minimum value for undertemperature
- additional integral over- and undertemperature monitor "ASF" (Auto-Safety-Function) automatically following the setpoint value at a preset tolerance range; audible alarm is activated in case of over- or undertemperature, heating of the individual shelf is switched off in case of over- temperature
- resolution of display and setting accuracy: 0,5 °C below 99,9 °C, 1 °C above 100 °C
- automatic overtemperature protection for each thermoshelf separately (MLOP-Multi-Level-Overtemperature Protection) switching the heating off at approx. 3 °C above set temperature
- mechanical temperature limiter TB protection class 1 switching the heating off at approx. 20 °C above max. oven temperature
Textured Stainless Steel Casing - w x h x d: 710 x 760 x 550 mm
- full-sight glass door, on the inside a spring-loaded 15 mm thick glazed panel in safety glass with anti-splitter screen on the outside
- rear zinc-plated steel
Interior - Heating Concept - w x h x d: 545 x 465 x 400 mm, 101 l
- hermetically welded stainless steel interior of extremely corrosion-resistant, electropolished stainless steel, material no. 1.4404
- additional interior mountings of stainless steel material no. 1.4404 (removable for cleaning); consisting of mounting at the sides with guide bars for thermoshelves, on top (diffusor) as well as a drip tray
- all tubings made of stainless steel material no. 1.4571
- plug connections for thermoshelves at the rear
- 1 thermoshelf of stainless steel material no. 1.4404 with integrated large-area heating
Temperature Range
- from +20 °C up to +200 °C
Voltage / Power Rating
- 230 V (+/- 10%), 50/60 Hz
- ca. 2,400 W
