BD8400W Series Dehydrators
Max Capacity 8400 SCFD (9911L/h), Output Pressure 0 to 15 PSI (0 to 103.4 KPa) Field Adjustable, Single Pressure Outlet, with Real-Time Remote Management

Rev : 6 | Rev date : 09 Jan 2024

PRODUCT DESCRIPTION

The BD8402W series dehydrators are used for pressurisation of broadcast antennas and transmission lines. The dehydrator removes the moisture from damp ambient air to deliver a reliable, constant, on-demand source of dry, pressurised air.  The inherent reliability of the BD series design, combined with the high output capacity make these units an ideal choice for pressurisation of broadcast systems. Low pressure systems (suffix LP) are available for applications where reduced pressure is required, for example; pressurization of broadcast antenna radomes, broadcast waveguide transmission lines or broadcast STL systems. The BD8402W Series dehydrators employ a fully digital operating platform offering the most accurate readings of operating variables, either from the front panel or by a remote connection.
