Jaeger Plastic Tower Packing - Low Profile Rings

Jaeger Low Profile Rings have a unique geometry made of ridged cylindrical surfaces and linear internal braces which provide larger surface areas for thin-film liquid formations and a multiplicity of drip points. When randomly installed, the bed forms an integral reticulated structure with excellent resistance to deformation to allow higher bed heights than other types of packing. Low Profile Rings have a low aspect (height/diameter) ratio of 0.3 compared to 1.0 for standard cylindrical ring type packing. The low aspect ratio offers opportunity for efficient gas and liquid contact and increased performance. Low Profile Rings have no protruding edges which minimizes the chance for nesting and offers more uniform liquid distribution. With low packing factors, Low Profile Rings allow increased hydraulic capacity while maintaining a low pressure drop.

Low Profile Rings are available in three nominal sizes: 1", 2", and 3½" and in most common injection-moldable plastics. Inventories are available in Houston, Texas and from our plant in El Dorado, KS.

BENEFITS		FEATURES
	When randomly installed, the bed forms an integral reticulated structure with excellent resistance to deformation to allow higher bed heights than other types of packing.	Low Profile Rings have an aspect ratio (height/diameter) of only 0.3.
	The low aspect ratio offers opportunity for efficient gas and liquid contact and increased performance.	Low pressure drop.
	Low Profile Rings have no protruding edges or appurtenances which minimizes the chance for nesting and offers more uniform liquid distribution.	Corrosion resistant.
	With low packing factors, Low Profile Rings allow increased hydraulic capacity while maintaining a low pressure drop.	Unique geometry, which maximizes turbulent mixing between phases, while allowing free gas flow through the packed bed.

Physical Properties of Other Jaeger Packings

Values are based on specific surface area >43 sq. ft./cu. ft. Wetting problems are observed most frequently with plastic packings, but generally become acute only at <2 gpm/sq. ft. When operating below this value, as in vacuum distillation, new packings should be chose which have better wetting characteristics than those replaced. Be certain to take capacity changes into account. If materials with poorer wetting properties must be specified, the bed height may have to be increased or a smaller size (more efficient) packing used.
