Rugged, mid-size monitors that can be used as front-office PCs or in hazardous
area.
Slim and Economical
With its moderate weight and small footprint, the VT750ES is ideal for
applications where both space and budget are limited.
Durable
The VT750ES is fully enclosed in a sealed, NEMA 4x, easy-open, stainless steel
case. The chassis has no external vents, so nothing can get under its skin,
including weather, dust, dirt, moisture, oil, chemicals or other harsh
contaminants. A hard-anodized aluminum heat exchanger and internal heat
management system keep it cool in environments where ambient temperatures
approach 50°C -- without using outside air. With its lightweight yet rugged construction, and either pre-cabled or bulkhead connectors, the VT750ES is easily mounted on walls, stands, arms or other industrial equipment. With optional brackets, it conforms to VESA flat panel mounting standards.

Purge System Mounting to Side (L/R), Top or Bottom

_____________________________________________________________

Purge System w/ Pressure Switch (Class 1, Div 1 Protection)

This Rapid Exchange® purging system operates on a supply of
compressed instrument air or inert gas. It regulates and monitors pressure
within sealed (protected) enclosure(s), in order to prevent combustible
dust accumulation or remove and prevent flammable gas or vapor
accumulations. The system accomplishes four air exchanges and maintains
a “safe” (0.25”) pressure. The system includes an Electrical Power Control
Unit (EPCU) that monitors system operation and controls enclosure power.
All start-up requirements must be satisfied before the EPCU will energize
power to the enclosure(s). These processes reduce the hazardous
(classified) area rating within the enclosure(s), in accordance with the NEC
- NFPA 70, Article 500, NFPA 496 and ISA 12.4.

OPERATION

In accordance with system instructions, start-up requires air supply to be engaged
and EPCU power to be energized. The system must perform an exchange cycle
(determined by the safe pressure flow rate — 5 minutes minimum) before power
can be energized. Loss of safe pressure causes the EPCU to deenergize power to
the protected enclosure(s). The purge system includes an explosion proof
differential pressure switch with form “C” contacts for audible of visual alarm
systems.
