BD420*W* Dehydrator Series
BD420*W* Automatic Dehydrator, 110-125 VAC 50/60Hz or 208-253 VAC 50/60Hz

Rev : A | Rev date : 12 Jun 2023

The dehydrator removes the moisture from damp ambient air to deliver a reliable, constant, ondemand source of dry and pressurised air, which is critical to prevent the systems from performance and reliability degradation by condensation. The BD4200W series dehydrators offer pressurization solutions to transmission lines and antennas in both telecom and broadcasting applications. Its low pressure models (suffix LP) are suitable for applications where reduced pressure is required, for example, pressurisation of broadcast antenna radomes, microwave waveguides and other transmission lines. The inherent reliability of the BD series design, combined with the high output capacity and remote real-time data capabilities make these units an ideal choice for pressurisation of systems at unattended sites. The BD4200W 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 IP connection.
