ADH NETCOM Automatic Air Dehydrator with Ethernet Communications
The ADH models of automatic air dehydrators have a successful history of delivering pressurized dry air for telecommunication antenna pressurization systems since 1986 and is considered one of Environmental Technology's premier product lines. This is evident with thousands of units in the field today and the number of units still in service since the product line's inception. Many of the first units shipped are still in service today more than 20 years later.
In 1991 Environmental Technology introduced the ADH–2COM and entered the world of network managed equipment. These units featured RS-422/485 networking and provided support for the Scientific-Atlanta protocol, terminal monitoring, Master-Slave configuration and redundant dehydrator pairs. Since that time the ADH–2COM, and later the ADH–2A COM and ADH–3COM, have been integrated into M&C systems through out the industry.
Today, Environmental Technology continues the evolution of the ADH product line with the introduction of the new ADH NETCOM automatic air dehydrator with Ethernet communication. The ADH NETCOM dehydrator pushes automatic air dehydrator technology to the next level with integral support for HTTP, SNMP, UDP and TFTP communications while maintaining legacy communications support. With a wide range of field configurable options the ADH NETCOM automatic air dehydrator is ideal for both new installations and as a direct replacement for in service dehydrators.
The Standard ADH NETCOM Automatic Air Dehydrator for Rack and Wall Mounting
- Easier to order and deploy than other automatic air dehydrators with less part number options and fully configurable in the field.
- A drop in replacement for previous ADH models in service and in specifications.
- Future-proof software based features allow updates and upgrades in the field; next generation features easily downloaded and added through-out the life time of the product.
- Remote monitoring and control expanded from previous models with a web interface and support for SNMP, UDP, TFTP and Scientific Atlanta protocol.
- Ethernet, RS-422/485, RS-232 and alarm relay outputs expands networking options.
- Simple, automatic power connections for 100-240VAC or ±20-75VDC A smaller, lighter chassis is only 16 pounds (24 pounds for outdoor NEMA) and extends only 12.5” into rack mounting systems.
- Standard indoor units can be configured for either rack and wall mounting. Rack mounted units can have mounting brackets installed at 0”, 2” 6” or 8” from front of unit.
- Product lifetime of 15+ years; including the compressor which features brushless motor and metallic inlet muffler instead of fiber filter.
The ADH NETCOM NEMA Automatic Air Dehydrator for Outdoor & Mobile Applications
- All the functionality and configurabilty of the standard ADH NETCOM automatic dehydrators.
- A durable, light-weight IP66, NEMA 4X enclosure weighs just 24 pounds (11 kg).
- A redisgned component assembly, unique from standard units, allows for smaller over-all dimensions while maintaining durability.
- The ADH NETCOM NEMA automatic dehydrator is not simply the standard dehydrator dropped into a weather-tight enclosure. Special attention has been paid to also make the ADH NETCOM NEMA automatic dehydrator ideal for mobile and other high vibration applications.
- Optionally available with Mil-Spec connectors for communications and power.
The ASM–1 Smart Manifold Automated Air Distribution Manifold
- Distributes dry low pressure air from one or more sources to one or more transmission lines.
- Designed to work in conjunction with ADH NETCOM automatic air dehydrators while also being compatable with other dry air sources.
- Continuous system monitoring allows leaking lines to be isolated while the rest of the system remains pressurized.
- Periodic automated line testing can identify future line leaks for planning maintenance before critical failures.
- Programmable pressure relief valve to bleed off excess system pressure common with high solar gains.
- Configurable Parallel Pumping operation combines multiple ADH NETCOM dehydrators for increased system capacity.
- Configurable Redundant Pumping operation combines multiple ADH NETCOM dehydrators for increased system reliability.
- The same chassis mounting, power supply and communications options as the ADH NETCOM automatic dehydrators simplifies system design.
