• Ease of installation – allows for fast hookup.
• Standardized components and design – minimizes spare parts requirements.
• Customizing options – Numerous options for changing the system design for individual plant specifications.
• Class 1, Division 2 Compressed Air Sample System – unique low-cost design for sampling instrument air in a hazardous or classified location.

Numerous options are available for customizing these systems to individual plant requirements. The drawings above and on the next page show some typical systems. The model above shows the basic system set for dewpoint monitoring, with the following options: inlet filter with manual drain valve, flowmeter, instrument built on the DDSS panel, and a NEMA 4X enclosure.

This enclosure can also be supplied with an optional Z-purge for Class 1, Division 2 applications. The drawing on page two shows the basic DDSS with the inlet filter with drain valve and flowmeter options. With an optional high-pressure regulator, either of these systems can be supplied suitable for sample pressures up to 3000 PSIG.
