V. Principles of Operation
The main component of the heat exchangers is counterflow aluminum element through
which heat transfer occurs.
Ambient blower draws ambient air from the bottom inlet through an aluminum mesh air
filter, through the element and exhaust it through a discharge grill.
Cabinet blower draws cabinet air from the top inlet through the element and exhaust it
through the bottom discharge into the cabinet.
VI. Specific Model Data
Mounting
Panel Mounted Heat Exchangers KTHE300 and KTHE500 are equipped with two vertical mounting
rails. Using these rails, the units may be mounted to any available vertical surface on the enclosure.
Refer to page 5 for location of all mounting holes and cutouts.
Make sure cutouts do not interfere with components inside your cabinet.
Proper alignment of air inlets and outlets is essential for optimum Heat Exchanger performance
All Kooltronic externally mounted Heat Exchangers are fully gasketed to ensure proper sealing. This
seal is necessary to maintain the integrity of the closed-loop system.
Use all existing mounting holes to insure stability and a tight seal.
