I. Introduction

Kooltronic Heat Exchangers are designed to provide a cool environment for your electronic or electrical
components. There are models to fit virtually all sizes and shapes of electrical or electronic enclosures. Our
“closed loop” design also ensures that your components will not be exposed to hot, dirty operating conditions.

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.
