Self-reactivating dry air breather introduced by Brownell is designed to prevent contamination of wind turbine gearbox lubricating oil by water and condensation. With its robust, all-weather construction, the REGEN8 features automatic process control, including a telemetry option for remote monitoring and control.
Many lubricating oils have a water vapour adsorption characteristic. And, says Brownell, commercially available lubricating oils are delivered by most manufacturers with a low residual water content. However, maintaining this low residual moisture level throughout the gearbox life is a major challenge and requires an active moisture control and management system.
Brownell's REGEN8, which can be used for wind turbine gearboxes of up to 1000 litres free air space, ensures that the water vapour in the gearbox is maintained at a safe level. Water vapour is adsorbed using an active adsorbent in a twin channel system that ensures a constant supply feed of dry air into the gearbox: when the adsorbent is saturated an automatic reactivation process is initiated which restores the adsorbent to its maximum efficiency level.
Also new from Brownell is a moisture adsorbing polymer that can be shaped and fixed within any packaging medium. Seen as a practical alternative to conventional desiccant bags, the polymer is easily cut, formed, punched, shaped and thermo-formed or may be supplied in a standard 200 x 200mm board size. It provides an excellent level of clean drying in a range of products from electronics, machinery, optics and instruments to pharmaceuticals and food.
By allowing complex shaping, pliability and mechanical fixing, this humidity adsorbing board helps ensure maximum space occupancy. It is low dusting, with no risk of loose desiccants from broken bags, and is not water soluble.
