Release details
Modified features
Hardware: added Harsh Environment option
This release includes the addition of the Harsh Environment coating option. This option is for use in sulfur-rich
environments such as petroleum and chemical plants, oil refineries, paper and pulp recycling plants, sewer and
wastewater plants, and steel mills. The atmosphere produced by various chemical technologies in such facilities
causes a serious corrosion problem for many metals used in electrical apparatus. Humidity and temperature
variation contributes to the corrosion process leading to electronic equipment failures.
The Harsh Environment coating option:
•
protects electronic equipment from corrosive gases
•
reduces machines and processes down time
•
minimizes equipment maintenance and repair cost
The order code has been changed to introduce the harsh environment option “-H”.
