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
ControlCOCKPIT: TwinDISPLAY. 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)
