The VT752ESC is a NEMA 4X (IP66) HMI system designed to meet Class 2, Div 1 protection. The purge system uses a pressure switch to automatically trigger alarms in case of pressure loss.
Durable
The VT752ESC 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 VT752ESC 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.

X Type Purge System w/ Pressure Switch (Class 2, Div 1 Protection)

This Rapid Exchange® purging system that 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. In Class II Areas, the
system maintains a "safe" (1.0") pressure. In addition, 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 the air supply to be
engaged and EPCU power to be energized. In Class II Areas, all dust must be
removed from the enclosure(s). The enclosure protection vent (if used) must be
tested and enclosure(s) must be sealed. The EPCU power control switch must be
activated and the system will self-test. The enclosure pressure control regulator is
then used to set a safe reading on the enclosure pressure gauge. In Class II Areas,
power will energize shortly after safe pressure is stable. Loss of safe pressure
causes the EPCU to de-energize power to the protected enclosure(s). All systems
include form "C" contacts for audible or visual alarm systems.
