Liquid receivers - Liquid separators

Product catalog summary
Overview
The document outlines the technical specifications and descriptions for Alfa Laval's liquid receivers and separators, specifically models LRDV, LRV, LRDH, LRH, SAD, and SA. These components are crucial in refrigeration and air conditioning systems for managing refrigerant load variations and protecting compressors.

Liquid Receivers (LRDV, LRV, LRDH, LRH)
These receivers are designed to handle load variations and store refrigerant during maintenance. They are suitable for both water chillers and air conditioning systems, available in vertical and horizontal configurations with capacities from 5 to 1000 liters. The receivers come in two-piece (LRDV, LRDH) and three-piece (LRV, LRH) constructions, offering various certifications.

Liquid Separators (SAD, SA)
Installed on the suction line, these separators protect compressors from liquid slugging, ensure consistent oil return, and reduce vibrations, thus enhancing compressor efficiency and longevity.

Quality and Testing
Alfa Laval adheres to ISO9001 quality procedures, conducting pressure testing and helium leak detection on each pressure vessel to meet Alfa Laval standards and other regulations.

Technical Specifications
The document provides detailed specifications, including design pressure, test pressure, design temperatures, dimensions, connection types, refrigerant volume, and weight for each model.

Certifications and Approvals
Products are available with certifications such as CE, GOST, SQL, ASME, and UDT, depending on the model and volume. Some models may have limitations based on shell diameters.

Specifications
Models are categorized by capacity with specifications for dimensions, connections, refrigerant volume, and weight. Dimensions are in millimeters, and connections can be brazed or welded, with Rotalock options available.

Procedures
Refrigerant connections can be made using brazing or welding. CE approved sight glasses are available in two diameters based on receiver size.

Norms and Standards
CE approval for sight glasses indicates compliance with European standards.

Recommendations
Select sight glass diameter based on the receiver's diameter.

Company Profile
