All-round surface heating
Precise temperature control in industry, science and research: Optimum temperature distribution is just one of many advantages of the unique Memmert heating concept.
Documentation
Quality included: data logger, remote control and logging software, interfaces for programming, storage and printing, as well as a MEMory Card for programming and documentation.
- Temperature progress and monitoring devices
For thermal safety and operating comfort, the highest Memmert controller class is uncompromisingly perfect for the Universal Oven U. Complex thermal processes in science, research and industry are programmed without problem and repeated as often as necessary with the help of a chip card. A multifunctional fuzzy controller, with permanent performance adjustments and integrated self-diagnosis system, as well as two high-quality platinum temperature sensors Pt100, ensure absolutely reliable temperature control and the highest process safety and control accuracy in the universal Memmert ovens.
- Temperature range: 30 °C (at least 5 °C or 10 °C above ambient) to 250 °C
- Temperature variation (time): < ±0.25 °C at 150 °C
- Multiple overtemperature protection: If the electronic heating control should fail, heating is switched off at a fixed level of 10 °C above the setpoint. An adjustable overtemperature controller TWW protection class 3.1 (optional adjustable electronic temperature limiter TWB protection class 2) takes over control at a preset temperature in case of failure. ASF Automatic Safety Function - a unique safety function - for over- and undertemperature automatically following the setpoint in a freely selectable tolerance range. An alarm sound is activated in case of over- /undertemperature, and the heating is switched off in case of overtemperature. In addition a mechanical temperature limiter, TB, switches off heating permanently if the maximum permitted oven temperature is exceeded by approx. 10 °C.
- Adjustable undertemperature alarm
- 2 high-grade platinum temperature sensors Pt 100 in a 4-wire circuit (for stable long-term transmission of measurement signals) communicate with each other and ensure uninterrupted error-free temperature control at constant working temperature
- Digital programme control (programmable to the minute) for temperature profiles consisting of up to 40 ramps
- Weekly timer programmable to the minute
- Air flap adjustable by servo motor for fresh air intake
- Speed of fan can be controlled at 10% intervals, or shut down
- Heating power distribution balance to optimise temperature uniformity
- Simultaneous display of all parameters, such as temperature, weekday, time, fan speed, air flap position and number of ramp
- Visual and acoustic alarm in case of over-/undertemperature
- Alphanumeric text display in different languages (D/UK/E/F/I)
- Function signals for stand-by, operating mode, heating and over/undertemperature
- Internal log memory with 1024kB to save temperature and error states, with timestamp to the minute
- Chip card control including 1 MEMoryCard XL with 32 kB memory capacity (max. 40 ramps)
- Serial RS-232 communication interface (option: USB) and software Celsius to control the appliance and to read out the appliance's internal log memory
- Parallel printer interface for printout of log data via an external PCL3-compatible inkjet printer (USB available via converter)
Fraunhofer TESTED DEVICE
Memmert Universal ovens UFP 500 and UFP 800 in the standard version are certified for their cleanroom suitability.
Pass-through oven for loading from both sides
Universal oven UFP 800 TS saves time when loading and reduces the danger of contamination.
Oven Drying method
Scientific examination in the laboratory demonstrates: thermally altered wood improves the tonal quality of musical instruments.
Application PCBs
The German Electrical and Electronic Manufacturers’ Association (ZVEI) recommends: Drying PCBs in a vacuum reduces drying times compared with a standard warming oven and saves energy.
