Description

ADH Sirocco Datasheet ADH Sirocco Manual  ADH Sirocco Installation Sheet

The ADH SIROCCO automatic air dehydrator supplies low pressure dry air to keep waveguide and coaxial cable dry. Output pressure is user-configurable between 0.10 psig and 7.50 psig (7 mbar – 517 mbar) in 0.01 psig (0.67mbar) increments. Factory default pressure is 0.5 psig (34.5 mbar). Operational monitoring and alarms are also user-configurable to suit unique or changing system requirements.

Three configurable alarm relays are also included. Communicated operational information includes output pressure, duty cycle, temperature, compressor hours, and air drying canister status.
The ADH SIROCCO automatic air dehydrator uses a brushless dual-diaphragm pump for long life and operates with exceptionally low noise and vibration levels. The air drying canisters use aluminum oxide desiccant for high efficiency. Desiccant automatically regenerates at fixed time intervals for additional energy savings and long desiccant life.

The ADH SIROCCO automatic air dehydrator requires only 5-1/4″ (3-U) of rack space and is just 12″ (304.8 mm) deep. Mounting hardware allows for flexible installation options including dual- and single-post rack mounting and wall mounting. The standard unit weighs just 16 lbs (7.26 kg).

The ADH SIROCCO automatic air dehydrator operates from 100-240 VAC, 50/60 Hz. The dehydrator consumes a maximum of 75 watts during regeneration and approximately 40 watts otherwise. Heat dissipated is up to 255 BTU/hr during regeneration and approximately 136 BTU/hr otherwise. This product creates an exceptionally low heat load for an automatic dehydrator.
