PEM Cooling Duct Kit

SKU: 44-TES-RO-DUCT Categories: , , Tags: , , ,

This duct, is what cools the PEM transistor heat sinks, fed by the PEM Cooling Fan, and an essential component in keeping the IGBT Power Transistors from overheating.

As these age, they become brittle, develop cracks and fissures, and limit the amount of cooling provided.

We recommend pro-active replacement of this duct assembly every 7 years to prevent any surprise downtime.

This replacement Silicone Rubber Air Duct Hose is double helix, and thicker than the OEM version for longer life including high temperature capability (maximum 450° F continuous / 500° F intermittent).

New, this hose is extremely flexible and pliable, but a bronze coated spring-steel wire support helix prevents it from collapsing. The fiberglass fabric cover and fiberglass cord are both impregnated and coated with silicone rubber.  Available in red-orange color only.



A PEM removal is required in order to replace this duct.

We also supply stainless steel hose clamps, replacing the OEM provided plastic tie wraps which become brittle with age, and snap.
