Aavolyn # 3214G1, Cast Iron TY655-4 Water Cooled Packing Case Assembly

Water cooled to reduce heat

The AAVOLYN Type 655 series water cooled case, because of its unique design brings a high cooling flow rate to the sealing surface. Heat transfer is directly enhanced by the amount of surface area exposed and the reduced distance between the heat source and the cooling.

Special features such as internal O-ring seals around the water chambers and encased O-ring seals between each cup prevent any leakage of gas into the water cooling patterns.

Each water cooled cup is fitted with access plugs to flush out the internal water surfaces where scale may build up. This scale buildup can reduce heat transfer and restrict coolant flow during the life of the packing case.
