	401 Random Packing Bed Limiter Attached to support rings or bolting clips above the packed bed, a bed limiter prevents the loss of packing if high pressure drop or surge conditions cause sudden bed expansions. Lightweight mesh is attached to the bed limiter to prevent carryover of smaller-sized packing. Integral bed limiters may be used with most Koch-Glitsch gravity distributors, thereby eliminating the need for a separate bed limiter. This reduces cost by eliminating one device and its support ring, and minimizing the risk of maldistribution caused by liquid splashing on a separate bed limiter. The overall height of bed limiters is about 2 inches. Back to Top


	402 Ceramic Packing Hold Down Koch-Glitsch Hold Down Plates rest directly on top of the packed bed and are used exclusively to hold ceramic or tower packing in place. They are not recommended for metal or plastic packing. The plates inhibit fluidization of the top layer of packing during tower operation. Like the bed limiters, they deliver at least as much throughput capacity as the packing at low pressure drops. The overall height of hold down plates is usually 3 inches, but can be as high as 6 inches. Back to Top
