Product Description
The Plastic Bilayer Rosette Ring, also known as Double-layer Tellerette Packing, is an innovative plastic packing material featuring two layers of circular rings with a stiffener in the center. This unique structure significantly enhances the compressive strength of the packing bed, making it highly effective in various applications. In addition to its high energy efficiency and low-pressure drop, the special design also allows for a higher liquid holding capacity within the packing, which results in longer residence times for the liquid in the column. This prolonged interaction between the gas and liquid phases increases the contact time, improving mass transfer efficiency.
