3.5 Back-channel Cooling Overview
A unique back-channel duct passes cooling air over the heat sinks with minimal air passing through the electronics area.
There is an IP54/Type 12 seal between the back-channel cooling duct and the electronics area of the VLT
®
drive. This back-
channel cooling allows 90% of the heat losses to be exhausted directly outside the enclosure. This design improves
reliability and prolongs component life by dramatically reducing interior temperatures and contamination of the electronic
components. Different back-channel cooling kits are available to redirect the airflow based on individual needs.
