Description
In batch mode the product is pumped from the vacuum vessel and then returned. As it re-enters the vessel it forms a thin film over a spreader disc, offering a large surface area to the vacuum, hence releasing dissolved gases. As the product is recirculated over time, more gas is released.
product can be drawn off at the rate required by the progressing cavity pump of the FT74XA or FT174X.
Product can either be drawn off until the vessel reaches its minimum limit, or the FT51 can automatically top up the vessel from an external container, using the vacuum to draw in the amount required to top up the vessel. The automatic level control maintains a max volume of approximately 10l in the vessel.
Some products benefit from spray deaeration and in batch mode the spreader disc can be replaced by the supplied purpose designed spray ball.
This uses multiple nozzles to produce a fine mist of product, enabling deaeration to be performed over the enhanced surface area of the small droplets.
