I. Introduction

Kooltronic TrimLine Heat Exchangers are designed for indoor applications with ambient
temperatures from 50°F to 131°F and maximum allowable enclosure temperature of
160°F. These heat exchangers utilize a counterflow airstream, for maximum heat
transfer efficiency in a closed-loop system, providing cooling within sealed electronic
cabinets.

This Manual provides you with the necessary general information for properly installing
and operating Kooltronic Heat Exchangers.  Unit specific technical data and mounting
instructions are presented later in the Manual.
