 New automation software technology has caused
a major migration of computers to be placed in the actual
manufacturing area of production plants which may be classified
as hazardous areas. VarTech's rugged Purged series of industrial
operator interface workstations and computer systems allow
for the placement of totally enclosed computers into hazloc
areas classified as hazardous (explosive or flammable). Intrinsically
safe, this purging (pressurization) approach ensures that
there will always be a continuous clean air-flow out of the
enclosure thereby preventing the intrusion of explosive gasses
or dust into the enclosure. These hazardous area computers
will not cause conditions that may result in an unstable environment.
VarTech offers full NEMA 4X workstations
and computers with hazloc protection classifications:
1. Class
1, Division 1, Groups C, D, and optional B
These workstations and LCD computers are equipped with purge
systems which insure intrinsic safety in areas where flammable
or explosive gasses or vapors are very likely to exists in
the air during normal operating conditions. Groups C and D
use an automatic purge while Group B requires a standard purge
system.
2. Class
1, Division 2, Groups A, B, C, D
These workstations and LCD computers are equipped with purge
systems which insure intrinsic safety in areas where explosive
or flammable gasses or vapors could possibly exist in the
air during an abnormal occurance such as a leak.
3. Class
2, Division 1, Groups E, F, and G
These workstations and LCD computers are equipped with purge
systems which insure intrinsic safety in areas where ignitable
dust, carbon, or ignitable material is very likely to exists
in the air during normal operating conditions.
4. Class
2, Division 2, Groups E, F, and G
These workstations and LCD computers are equipped with purge
systems which insure intrinsic safety in areas where ignitable
dust, carbon, or ignitable material possibly could exist in
the air during an abnormal occurance such as a spill.

for more information on intrinsically safe & purged control
monitors, computers and workstations for Haz Loc areas.
