Water-Cooled Condensing Units

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
Detailed technical specifications are provided 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, including 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 list the refrigerating capacity (Q0) for each model at different evaporating temperatures, highlighting performance variations across the range.

Overview
The document provides technical specifications and dimensions for various models of condensing units manufactured by Officine Mario Dorin S.p.A., including data on refrigerating capacity, evaporating temperature, and overall dimensions.

Specifications
Multiple models of condensing units are listed, each with specific refrigerating capacities at different evaporating temperatures, identified by codes such as WU-H281SB, WU-H300CS, etc. Capacities are provided in a tabular format, indicating performance at various temperature levels.

Procedures and Standards
References to safety and operational standards are included, such as the use of safety valves and suction valves, and the importance of proper water connections for cooling tower water and mains water.

Dimensions
Detailed dimensions for each model are provided, including measurements for length, width, height, and connection sizes, crucial for installation and integration into existing systems.

Key Components
Key components such as the water inlet/outlet, suction valve, safety valve, and refrigerant outlet are highlighted, essential for the operation and maintenance of the condensing units.

Contact Information
The document concludes with contact details for Officine Mario Dorin S.p.A., including their address in Florence, Italy, and communication channels such as telephone, fax, and email.
