Control unit FS860S

for use on large enclosures in Ex zones 1 and 21

Features
  • The FS860S was developed for applications in which large volumes need to be purged in a short period of time. The main areas of application are, for example, the encapsulation of electrical machines (motors) and oversized control cabinets.
  • The 2-inch outlet enables purge rates of up to 100 m3/h at low pressure levels in the Ex p-housing.
  • As an option, the FS860S can be designed for a housing pressure range of up to 27 mbar, which enables purging rates of more than 100 m3/h .
  • Compact system: Installation directly in the Ex area or in the Ex p-enclosure
  • Ex p-system with patented proportional working pressure and flow sensors
