Application Guide

1. Introduction

The content of this material applies only to “Optyma

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.
