{"product_id":"eti-adh-netcom-automatic-waveguide-air-dehydrator","title":"ETI ADH NetCom Automatic Waveguide Air Dehydrator","description":"\u003cp\u003eThe ETI ADH NetCom is an automatic, regenerating air dehydrator that keeps antenna waveguide and dielectric coaxial cable filled with dry, pressurized air so moisture never degrades the signal. A brushless dual-diaphragm compressor feeds aluminum-oxide desiccant canisters that regenerate on measured dew point rather than a fixed timer, saving energy and desiccant. Output pressure is programmable from 0.3 to 7.5 psig, and the unit is monitored and controlled over Ethernet with a web interface or SNMP, with RS-422\/485, RS-232 and three alarm relays for legacy systems. It fits 3U of rack space (or mounts on a wall), runs from 100-240 VAC or optional ±20-75 VDC, and supports master\/slave operation for parallel or redundant pumping.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAutomatic, dew-point-triggered desiccant regeneration\u003c\/li\u003e\n\u003cli\u003eProgrammable output 0.3-7.5 psig\u003c\/li\u003e\n\u003cli\u003eBrushless dual-diaphragm compressor\u003c\/li\u003e\n\u003cli\u003eWeb interface and SNMP over Ethernet; RS-422\/485, RS-232\u003c\/li\u003e\n\u003cli\u003eThree programmable alarm relays\u003c\/li\u003e\n\u003cli\u003eMaster\/slave operation for parallel or redundant pumping\u003c\/li\u003e\n\u003cli\u003e3U rack, single-post or wall mounting\u003c\/li\u003e\n\u003cli\u003eSoftware updates in service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003eADH NetCom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eETI ADH NetCom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eADH NetCom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eAutomatic regenerating air dehydrator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutput pressure\u003c\/th\u003e\n\u003ctd\u003e0.3-7.5 psig (20.7-517 mbar), default 0.5 psig\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum dew point\u003c\/th\u003e\n\u003ctd\u003e-40 °F\/°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInterfaces\u003c\/th\u003e\n\u003ctd\u003eEthernet (HTTP, SNMP, UDP, TFTP, TCP), RS-422\/485, RS-232, 3 Form C alarm relays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e100-240 VAC 50\/60 Hz; optional ±20-75 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower use\u003c\/th\u003e\n\u003ctd\u003e40 W typical, 150 W max (regeneration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e17 x 12.25 x 5.25 in (3U)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e16 lb (7.26 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eDual-post rack, single-post rack or wall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003ch4\u003eWhy do satellite antenna waveguides need a dehydrator?\u003c\/h4\u003e\u003cp\u003eMoisture that condenses inside waveguide and coax raises loss and VSWR, corrodes the line and can arc at high power.
