At Smart Family of Cooling Products, we want to provide our customers with the most relevant and up to date information available. With this in mind, we wanted to include easy to access start-up videos for the ERS CAT Sales & Service team.

This particular video demonstrates the start-up of our 80 ton Industrial Air Cooled Air Conditioning Unit (SACP83A-HS). We appreciate you taking the time to watch and we hope this is a helpful tool for the ERS CAT team.
