The ADH NETCOM dehydrator
The ADH models of automatic air dehydrator 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 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 s ideal for both new installations and as a direct replacement for in service dehydrators.
