Description

KOOLTRONIC Integrity NEMA 4/4X Heat Exchangers are intended to complement the Integrity NEMA 4/4X Air Conditioner product line for those applications that require the protection of closed-loop cooling, but can tolerate operating temperatures somewhat above the ambient.

Tested and rated by Underwriters Laboratories, these uniquely designed (Patented) stainless steel heat exchangers provide a clean, cool internal environment and also protect against the hazards specified for both Indoor and Outdoor NEMA 4 and 4X Enclosures.

These units can be mounted interchangeably with KOOLTRONIC Integrity NEMA 4/4X Air Conditioners for maximum flexibility in selection, upgrading or reducing cooling performance, if requirements change. The outer cover mounting holes as well as the cool air discharge and heated air return cutouts are identical (except cool air discharge of 32" model), so that either type of cooling unit could be used.

More powerful ambient-side blowers are used than in comparably sized standard KXHE and KXNP models, to overcome the added static pressure caused by the special baffles and dampers required to comply with NEMA 4/4X sealing and performance standards.

For extreme ambient temperatures and/or severely contaminated environments, the use of Water-to-Air Heat Exchangers or either Air-Cooled or Water-Cooled Air Conditioners is recommended.

KOOLTRONIC also designs and manufactures a variety of heat exchangers to meet unique specifications. We invite your inquiries about our modification and custom-design capabilities.
