Portable dry gas purging is more convenient and efficient

Easy-to-use single connection purging, dewpoint and pressure readout, user programmability and automatic purging cycle add major operational benefits to the robust units, which are ready to operate simply by connecting the equipment to the purge connection and can be maintained online.

Advanced capabilities and functionality ensure effective control of the purging operation. When a pre-selected pressure setting is achieved the gas supply is isolated and present gas flows to the exhaust port where the dewpoint is measured. Purging then continues until the desired dewpoint protection has been achieved.

Single connection purging eliminates any “pockets” of unconditioned gas found in traditional dual entry and outlet systems, while a choice of three selectable pressure cycles ensures that the dry gas influences all equipment space volume.

The system’s dewpoint monitor can check essential gas dryness prior to operation and a remote dewpoint sensing option monitors dryness, switching off and isolating the gas when the selected level is achieved.

For full flexibility and portability three models are available fitted with pumps and moisture adsorbing molecular sieves that are readily exchanged when saturated. These handy units maintain all operating functions of standard Brownell purgers and no additional gas supply is required.

Selectable programming can be set to view process control values and display dewpoint measurements in ºC or ºF with pressure in Kpa or psi. Four in-built leak testing capabilities verify the sealing standard of purged equipment.

The unit’s Dewpointstat gas control enables users to determine the amount of moisture contained within equipment and to implement an optimised gas and purging procedure for production control.

Modern systems and materials have potentially significant amounts of in-built moisture apart from that contained within the air. Humidity and water vapour can damage their operation and reliability and Brownell dry gas purging safeguards products ranging from electronics, switchgear and workstations to storage containers, underwater equipment and double glazing cavities.
