Air-Cooled Condensing Units AU 47°C

Product catalog summary

Introduction
This document introduces semi-hermetic condensing units designed for optimal performance, compact size, and low noise emissions. They are compatible with refrigerants R134a, R404A, R507, R407F, and R407A within specified limits.

Units Type AU
The AU units are standard for all applications, featuring air-cooled condensers with copper tubes and aluminum fins, high-efficiency motor fans, liquid receivers with safety valves, and anti-vibration dampers.

Application Envelope
Adherence to specified application limits is crucial for good operation and longevity. Operating outside these limits requires pre-approval by OMD.

Noise Level
OMD has selected motor fans that offer high performance with low noise emissions, complying with stringent noise regulations.

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

Condensers
Newly designed air-cooled condensers ensure optimal condensing temperatures, paired with motor fans for high airflow and low noise.

Motor Fans
The AU range features motor fans with hybrid blade construction for quieter operation, higher efficiency, and longer lifespan.

Accessories
Units can be equipped with accessories like filter driers, moisture-liquid indicators, solenoid valves, and oil separators, designed for easy assembly.

Conformity to PED Directive
The 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 catalog and DORIN software.

Technical Data
Includes a detailed table of technical specifications for various models, indicating parameters such as power consumption, airflow, and fan specifications.

Specifications
Performance data for refrigeration units using refrigerants R404A, R507, and R407F is provided. Suction gas temperature is standardized at 20°C, and capacity is measured with liquid subcooling. Contact technical service for unspecified conditions.

Performance Data
