The control technology for vacuum ovens is based on the Perfect class, but adjusted to the particular conditions in the vacuum: Multi-level controlling (MLC) and multi-level sensing (MLS) ensure precision and safety on all levels.

• Temperature range: 20 °C to 200 °C with a display accuracy of 0.1 °C
• MLC: Separate temperature control for each thermoshelf to a shared and predefined set temperature
• MLS: High-quality platinum temperature sensors Pt 100 in a 4-wire circuit (for stable long-term transmission of measurement signals), separate for each thermoshelf
• Vacuum pressure control for digital adjustment through integrated solenoid valves
• Signal for pump purging and switching off external vacuum pump
• Programmable inlet valve for fresh air and inert gas
• 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 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. MLOP Multi Level Overtemperature Protection for each thermoshelf individually, switches heating of invididual shelf off at about 3°C above setpoint. In addition a mechanical temperature limiter, TB, switches off heating permanently if the maximum permitted oven temperature is exceeded by approx. 20 °C.
