The VT700ESC is a NEMA 4X (IP66) HMI system designed to meet Class 1, Div 2 protection. The purge system uses an automatic pressure switch to automatically trigger alarms in case of pressure loss.
Durable
The VT700ESC can easily handle the punishment of harsh computing environments. They are proven tough in real world applications such as industrial production areas, outdoor kiosks and public terminals. The VT700ESC chassis has no external vents, so nothing can get under its skin, including 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 (122°F)-- without using outside air.
Easy Access
VT700ESC is designed with easy maintenance and up-grades in mind. A latched panel provides simple access to this NEMA 4X HMI system. With its moderate weight and dimensions, VT700ESC enables flexible mounting options.

Purge System w/ Pressure Switch (Class 1, Div 2 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 remove and
prevent remove and prevent flammable gas or vapor accumulations. The
system accomplishes four air exchanges and maintains a "safe" (0.25")
pressure. 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 enclosure power to be deenergized. In Class I areas, the user must perform an
exchange cycle (determined by the safe pressure flow rate—five minutes minimum)
before power can be energized. Loss of safe pressure requires immediate attention, unless power is deenergized. The purge system includes an explosion proof differential pressure switch with form "C" contacts for audible of visual alarm
systems.
