The VN2020 system replaces the VN/87plus generation. The system was launched in 2020 and replaces the VN 115/87plus and the VN/116/87plus. For VN 215 applications the VN301plus is the successor. The mayor changes on the VN2020 oil mist detector is:

  • Integrated pressure regulator including water/oil separator
  • New design of LED panel that ensures safe reading under operation!
  • New solid connection box, instead of connection socket!
  • Reset button position directly on the measuring head
  • New safe position of wire break resistance
  • New pressure sensor technology, no need for fresh air filters
  • CANopen and MODBUS RTU signals

For the VN2020 generation we supply:

  • Sale of new complete systems

VISATRON VN2020 continuously and simultaneously evacuate crankcase atmosphere from each crankcase compartment between two main bearings. The VN2020 use a header-suction-tube system for this purpose. The oil mist detector is positioned in the middle between two header-suction-tube sections located on the engine sides; from these sections, single-suction tubes branch off near the compartments. These tubes are considerably thinner than the header-suction tubes and they have a throttling effect. Owing to the large header-suction- tube diameter the vacuum and consequently the sample flow at each suction point remain virtually constant. The arrangement of the detector in the middle of the header-suction tube results in an optimally short sample running time in the tube system.

Key upgrades:

  • Integrated pressure regulator including water separator

  • Can be delivered with ATEX/ IECEx standard

  • New designed LED panel on measuring head with separate displays for safe reading during operation

  • New connection box instead of connection socket used on VN/87plus generation

  • New position of Wire Break Resistors inn connection box

  • Oil mist alarm confirmation (Reset) button position directly on measuring head

  • Latest SMD component and  pressure sensor technology used in measuring head

  • No need for scavenging air filters on VN2020- less spare parts required!

  • CANopen and MODBUS RTU signals!

  • New replaceable main cable between measuring head and connection box!
