WU series

Product catalog summary

Introduction
The WU series of water-cooled condensing units are engineered for optimal performance and compactness, compatible with refrigerants R134a, R404A, and R507 within specified limits.

Characteristics
These units feature a water-cooled horizontal condenser with discharge and safety valves, and a flexible hose on the compressor discharge piping. They are suitable for use with both mains water and cooling tower water.

Lubricants
Compressors are charged with POE oil with a viscosity of 32/46 cst at 40°C, suitable for HFC refrigerants.

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 catalogue and DORIN software.

Technical Data
The document provides detailed technical specifications for various models, including refrigerant and water circuit details, suction, and refrigerant outlet dimensions, and net weight.

Performance Data
Performance data is provided for different refrigerants (R134a, R404A, R507) at various evaporating temperatures. The data includes refrigerating capacity with a suction gas temperature of 20°C and 5K liquid subcooling. For conditions not listed, technical service should be contacted.

Key Performance Metrics
Tables in the document list the refrigerating capacity (Q0) for each model at different evaporating temperatures, providing a comprehensive overview of performance capabilities.

Overview
The document provides technical specifications and dimensions for various models of condensing units produced by Officine Mario Dorin S.p.A. It includes detailed data on refrigerating capacities, evaporating temperatures, and overall dimensions.

Specifications
