Application Guide

Introduction

The content of this material applies only to
“Optyma

TM

TRIO” condensing units. This product
is a Danfoss technology solution with the use of
three in parallel connected scroll compressors
in a robust foil framework with high eciency
micro-channel (MCHE) Danfoss condenser.

Even though a lot of benets for the use of
in parallel compressor systems exist, the
more important benets are the use of less
equipment, exibility on the capacity control,
use of few tubing lines, better control of energy
consumption and reduction of installation
time when compared to the use of dierent
equipment with single compressor systems
toobtain the same capacity.
