Sealed Enclosure Cooling from 22 Watts/°C to 68 Watts/°C
This passively sealed enclosure cooling device consists of two high-performance aluminum finned heat sinks bonded to the opposite sides of a common mounting plate. The HSC line has a high performance/cost ratio, due to the innovative use of advanced heat transfer and manufacturing technologies. ACT’s HSC units are easy to order online and offer fast shipping and easy control cabinet install. Perfect for automation equipment across various industries, anyone with a control cabinet will find one of ACT’s units to solve their thermal issue.
- Thin profile, i.e., only 3.70″ intrusion into the enclosure
