Heating and Drying Ovens

Vacuum Oven VO29

| PRODUCT MANUFACTURER: MEMMERT

Product Description

The VO29 vacuum oven is designed to ensure rapid and uniform temperature control of food, cosmetics, watches, books, PCBs, or injection moulds—without the loss of heat.

Memmert is one of the leading manufacturers of temperature controlled appliances. Made in Germany, these units are 100% AtmoSAFE meaning not only are you purchasing a superior product technologically, but also one that is environmentally friendly.

Whether you’re looking for smaller or larger volume chambers, working with standard applications, or requiring a high demand for functionality, programming or documentation - Memmert has you covered. STEQ America is proud to offer Memmert’s range of heating and drying ovens which feature user-friendliness and state-of-the-art communication interfaces as a standard. Each appliance is tested according to the strict requirements of DIN 12 880: 2007-05 and is equipped with maximum security capabilities to keep you, the operator, safe at all times.

Applications for heating & drying ovens include:

• Sample storage
• Water content
• Vacuum drying
• Dry content
• Conditioning
• Heat drying
• Material testing
• Annealing

New speed-controlled vacuum pump option

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 without the loss of heat.

NEW feature! The Memmert Vacuum Oven VO 29 now comes with a speed-controlled vacuum pump accessory option. Digital pressure control ensures rapid and gentle vacuum drying and its speed-controlled vacuum pump accessory saves around 70% energy.

Main Features and Benefits

  • Temperature measured through 4-wire Pt100 sensor individually for each thermoshelf
  • Sizes: 29 L (1 cu. ft. 230 V), 49 L (1.7 cu. ft. 230 V), 101 L (3.5 cu.ft. 230 V)
  • Working temperature range of min. 5°C above ambient up to +200°C
  • Setting accuracy temperature of 0.1°C
  • Control of standard components for vacuum:
    ­- 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)
    ­- Permitted final vacuum 0.01 mbar. Maximum leakage rate 0.01 bar/h
    ­- Adjustment range from 5 mbar to 1100 mbar - digital (LED)
    ­- Programmable, digitally controlled inlet for air
    ­- Vacuum drying process (vacuum cycles) is continued after power failure
    ­- Speed control optimized rinsing procedures for the pump membranes as well as signal output for pump ON/OFF
    -Vacuum connection with small flange DN16, and gas inlet with small flange DN16
  • Control of standard components for controller:
    ­- Digital display of all set parameters, such as temperature (Celsius or Fahrenheit), pressure (vacuum), program time, time zones, summertime/wintertime
    ­- TwinDISPLAY, adaptive multifunctional digital PID-microprocessor controller with 2 high-definition TFT color displays
  • Digital backwards counter with target time setting, adjustable from 1 minute to 99 days
  • VO direct heating: 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 2nd level)
  • Outer dimensions (WxHxD): 21.65 x 23.90 x 15.75 in
  • Interior dimensions (WxHxD): 15.16 x 12.01 x 9.84 in
  • Rear zinc-plated steel
  • Ethernet LAN, USB interface
  • AtmoCONTROL software on a USB stick for programming, managing and transferring programs via Ethernet interface or USB port
  • Program stored in case of power failure
  • AutoSAFETY: Additionally integrated over- and-under temperature protection "ASF", automatically following the setpoint value at a preset tolerance range, alarm in case of over- or under temperature, heating of the individual shelf is switched off in case of overtemperature, compressor in case of undertemperature
  • SetpointWAIT Function: the process time for the setpoint value does not start until the set temperature is reached
  • Autodiagnostic system for fault analysis
  • Safety approved: EAC, CE marked

Options

  • Noise-insulated vacuum pump module: PMP 29: Variable-speed pump module for VO 29 230 V, PMP 49: Variable-speed pump module for VO 49 230V, PMP 101: Variable-speed pump module for VO 101 230V
  • Works calibration certificate for one (freely selectable) temperature and pressure value (per themoshelf) according to customer specification
  • Premium Module: comprises the inert gas inlet (only size 49 and 101), extra connectors for thermoshelves, 1 (size 29), 1 (sizes 49/101), an additional thermoshelf (sizes 49/101)
  • Works calibration certificate for 3 temperatures: +50°C, +100°C, +160°C at 20 mbar pressure. Priced per thermoshelf
  • Temperature restriction for temperatures of +60, +70, +80, +95, +100, +120, +160 or +180°C (please indicate when ordering)
  • Flexible Pt100 for positioning in chamber or in load with socket, 4-pin, according to NAMUR NE 28, for external temperature recording (load temperature)

Accessories

  • IQ/OQ document with device-specific works test data for one free-selectable temperature and vacuum value, incl. temperature distribution survey at Memmert for 5 measuring points per thermoshelf to DIN 12880:2007-05
  • Supportive PQ check lists
  • Signal cable (3 m) for control of rotation speed and optimizing pump performance by demand-controlled activation of purge of Memmert pump (not required with pump module)
  • USB User-ID stick (with User-ID license): Oven-linked authorization license (User-ID-programme) on Memory Stick, prevents undesired manipulation by unauthorized third parties
  • USB Ethernet Adapter
