 VarTech's
rugged purged series of industrial LCD displays allow for the placement
of totally enclosed monitors 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
LCDs will not cause conditions that may result in an unstable
environment.
VarTech offers full NEMA 4X LCDs
with hazloc protection classifications:
1. Class 1, Division 1, Groups C,
D, and optional B
These LCD displays 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.
Sizes Supported:17.0" | 19.0"
2. Class 1, Division 2, Groups A,
B, C, D
These LCD displays 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.
Sizes Supported: 17.0" | 19.0"
3. Class 2, Division 1, Groups E,
F, and G
These LCD displays 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.
Sizes Supported: 17.0" | 19.0"
4. Class 2, Division 2, Groups E,
F, and G
These LCD displays 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.
Sizes Supported: 17.0" | 19.0"
