IS-IBC1 High Temperature Ducting and Hose

Rigid ducting should be used as much as possible in internal bubble cooling air flow systems, but there are portions of the system where only flexible ducting (hose) will do the job. The most common use of flex hose is to connect the distribution plenum to the pipes on the bottom of the die. However, not all flexible hoses will hold up when continually exposed to the heat that comes from the bottom of the die. The high temperature can quickly fatigue the hose causing significant leaks or even collapse. Some flexible hoses have a cloth inner lining, which over time, tends to be pulled away from the hose by the internal vacuum which results in a difficult to detect airflow obstruction.

Low-quality ducting becomes brittle and breaks under even normal plant conditions in a short amount of time.
Remember to pay attention to the bend radius as exceeding it increases chances for premature failure.

DuctingDRJ has a solution to your flexible duct hose requirements. A high strength hose capable of handling temperatures up to 500°F. This is an application proven hose is excellent for connecting the IBC exhaust and supply plenums to the die. The hoses that connect directly to the die come in ¾" to 3 ½" ID and compress a maximum of 25% of standard length. The main ducting sizes start at 4" ID and up and compress 50% of standard length. The following table gives you a variety of hose sizes to choose from (metric below).
