Aqua Environment 585 585 Series Moisture & CO Indicator 1/4" FNPT 5000 PSI

The visual indicator allows an operator to see a moisture indicating card in the high pressure line. The cards are seen through a high strength plastic window. The moisture card is divided into sections which progressively change color from blue to pink as moisture increases. Alternately other visual color changing indicators including a carbon monoxide indicator are available. Moisture indication tells when to change chemical drying cartridges. Normally cartridges should be changed when the indicator shows 40 to 60% relative humidity downstream of the dryer. Under high pressure, 60% relative humidity is still very dry air. For example, 3000 PSI air with a relative humidity of 60% has a dew point of -480 F.

Typical Applications:

• Humidity indicators in high pressure air lines
• Dryer / filter unit change indicators
• High pressure compressors
• High or low pressure air stations
• High or low pressure process industry lines and systems
• Instrument and high purity air lines

Installation

Use a suitable pipe thread sealant on the inlet and outlet threads. Flow should be through the indicator . Do not install the indicator in a tee to one side of the main flow. This would increase the time it takes for the indicator to respond. The indicator can be installed in a panel by making a 1.5" or larger hole in the panel such that the window and removable cap can extend out from the panel while the piping connections can be located behind the panel. The indicator is sufficiently light so it can be supported by the piping connections. It can be installed with the window facing any direction. The indicator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.
