Application Guide	1. Introduction

The content of this material applies only to “OptymaTM 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 efficiency micro-channel (MCHE) Danfoss condenser.

Even though a lot of benefits for the use of in parallel compressor systems exist, the more important benefits are the use of less equipment, flexibility 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 different equipment with single compressor systems

to obtain the same capacity.
