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
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
