MEMMERT VO49cool Cooled Vacuum Oven (+5°C ~ +90°C, 49L)

Temperature

Working temperature range from 5°C (at least 20 below ambient temperature) to +90°C

Setting temperature range from +5°C up to +90°C

Resolution of display for actual values: 0.1°C

Resolution of display for setpoint values: 0,1°C

Pressure (Vacuum)

Vacuum range: 5 to 1100 mbar

Pressure control: Digital electronic pressure control for a speed-controlled vacuum pump. Tubing for vacuum, air and inert gas are made of material 1.4571 (ASTM 316 Ti). Programmable, digitally controlled inlet for air.

Permitted final vacuum: 0.01 mbar

Maximum leakage rate: 0.01 bar/h

Pump control: speed control, optimised rinsing procedures for the pump membranes as well as signal output for pump ON/OFF

Connection: Vacuum connection with small flange DN16, and gas inlet with fresh air supply

Control technology

adjustable parameters: temperature (Celsius or Fahrenheit), pressure (vacuum), programme time, time zones, summertime/wintertime

Language setting: German, English, Spanish, French, Polish, Czech, Hungarian, Italian

ControlCOCKPITTwinDISPLAY. Adaptive multifunctional digital PID-microprocessor controller with 2 high-definition TFT-colour displays.

Timer: Digital backwards counter with target time setting, adjustable from 1 minute to 99 days

Function SetpointWAIT: the process time does not start until the set temperature is reached

Communication

Interface: Ethernet LAN, USB

Documentation: programme stored in case of power failure

Programming: AtmoCONTROL software on a USB stick for programming, managing and transferring programmes via Ethernet interface or USB port

Safety

Temperature control: mechanical temperature limiter TB, protection class 1 according to DIN 12880 to switch off the heating approx. 10°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 is switched off in case of overtemperature, compressor in case of undertemperature

Autodiagnostic system integral fault diagnostics for temperature control

Alarm: visual and acoustic

Heating concept

Thermoshelves: 1 connection for thermoshelves in the rear

VO cooling: Peltier cooling unit ensures a surface temperature distribution with a maximum deviation of ±1 K across the entire temperature range

VO direct heating: fuzzy-supported MLC (Multi-Level-Controlling) microprocessor controller adapting its performance to the volume (local temperature sensing)
