The ENC-HD series is a series of special outdoor panel cooling units which achieve environmental resistance intended for installation in harsh environments. It protects electronics from high temperatures/high humidity/salt damage, and maintains the best conditions for your outdoor control panels and communications racks. As with the indoor type, we have a full lineup of products with cooling capacities of 350W~2900W. Adequate corrosion-proofing has been applied to the cooler's internal radiation coil which is exposed to external air, and special surface treatment has been applied to the coolant pipes as well. There is also a hotwire resistant air speed sensor loaded to constantly observe cooling-side fan motor degradation. It also contains a full self-diagnosis feature which can perform external output to alert you of cooling failure, etc.
