Overview of AULC Component Units

The AULC series is designed for high performance, compactness, and low noise. Compatible with multiple refrigerants (R134a, R404A, R507, R407F, R407A, R704C, R449A, R448A, R450A, R513A, R452A) within specified operational limits from the E-AU 1LTZ079 catalog.

Unit Type and Standard Features

AULC units are standard models suitable for diverse applications. Key features include air-cooled condensers with copper tubes and aluminum fins, high-efficiency single-phase motor fans with protective grills, liquid receivers with safety valves, liquid piping, and a steel support frame. Discharge piping from compressor to condenser is optional.

Application Guidelines

Adherence to operational limits in the 1LTZ079 catalog is critical for reliability and longevity. Defining the most severe operating conditions is mandatory, and any deviations require prior approval from OMD.

Condensers

Newly designed air-cooled condensers optimize condensation temperatures and, combined with new motor fans, deliver high airflow with low noise emissions.

Motor Fans

Equipped with innovative Hy-Blade fans featuring a corrosion-resistant aluminum alloy core covered by fiber-reinforced plastic, these fans offer enhanced quietness, efficiency, and durability. They operate on 230V/1/50-60Hz motors with capacitors, include internal thermal protection, and support electronic frequency regulation. External grills provide safety.

Accessories

Optional discharge piping is available, customized per compressor type. The steel frame includes pre-arranged fixing holes for easy assembly and installation.

Compatibility and Matching with E-AU Units

A detailed matching table correlates AULC component units (without compressors) with E-AU condensing units (with compressors), ensuring correct pairing across series and ranges. Model codes and compatibility indicators guide selection.

Critical Information and Best Practices

• Strictly follow operational limits from the E-AU 1LTZ079 catalog to ensure performance and durability.
• Predefine the most demanding operating conditions; consult OMD for exceptions.
• Utilize Hy-Blade fans for improved efficiency and noise reduction.
• Consider optional accessories like discharge piping for tailored installations.
• Use matching tables to verify correct unit pairings.

Product Identification and Series

Units are categorized into two main types: condensing units with compressors (e.g., E-AU-H101CC) and component units without compressors. Each model is identified by series codes (H11, H2, H5) and range designations (H, L) indicating performance or configuration variations.

Technical Specifications

• Airflow (m³/h at 50Hz): Fan capacity.
• Power consumption (W at 50Hz): Electrical power usage.
• Current consumption (A at 50Hz): Electrical current drawn.
• Capacitor capacity (µF at 50Hz): Number and size of capacitors.
• Volume (liters): Refrigerant or oil volume.
• Connections: Sizes of rotational and welded connections (e.g., 1" 1/2").
• Net weight (kg): Unit weight.

These parameters are essential for selecting units based on cooling capacity, electrical compatibility, and installation requirements.

Dimensional Data

Dimensions are provided in millimeters, including length (L), width (P), height (H), and additional parameters (A, B, C, D) related to piping and mounting. This supports installation planning and system integration.

Accessories and Additional Information

Accessories are available on request, allowing customization. Piping details for compressor-to-condenser discharge lines specify dimensions for proper connection and installation.
