Air-Cooled Condensing Units AUI

Product catalog summary

Introduction
The AUI series of semi-hermetic condensing units with inverters are designed for efficient operation with HI compressor ranges, functioning between 20Hz and 90Hz (up to 75Hz for HI41 models). Benefits include energy savings, increased compressor reliability, reduced transient timeframes, and noise reduction. Compatible refrigerants include R134a, R404A, R507, R407F, and R407A within specified limits.

Lubricants
Compressors are charged with POE oil, with a viscosity of 32 cst at 40°C, suitable for HFC refrigerants.

Accessories
Units can be equipped with accessories such as filter driers, moisture-liquid indicators, solenoid valves, oil separators, suction flexible hoses, dual pressure switches, control fan pressure switches, and weather protection housing. The design allows easy assembly with pre-arranged fixing points on the steel frame.

Conformity to PED Directive
Dorin condensing units comply with the PED directive 97/23/EC, with a design pressure of 30 bar. For ASERCOM certified compressors, refer to the semi-hermetic compressors catalogue and DORIN software selection.

Technical Data
Technical data includes air flow rates, power consumption, and condenser capacity across various models and operating frequencies, presented in tabular form.

Performance Data
Performance data for refrigerant R134a details refrigerating capacity at various evaporating temperatures and frequencies, highlighting capacity with liquid subcooling. Technical services should be contacted for conditions not listed.

INTRODUZIONE / INTRODUCTION / INTRODUCTION / EINFÜHRUNG UNITA' TIPO AUI La nuova serie di unità condensatrici AUI è stata progettata per garantire un funzionamento idoneo con i compressori della gamma HI (INVERTER), in un campo di frequenze estremamente ampio, che varia da 20Hz a 90Hz (max 75Hz per modelli HI41). I principali benefici dell’INVERTER sono: risparmio energetico, aumento dell’affidabilità dei compressori, diminuzione dei transitori dell’impianto, riduzione della rumorosità. Tutte le unità AUI possono funzionare con R134a, R404A, R507, R407F, R407A entro i limiti indicati nel presente...
