Overview: This document outlines the technical specifications and operational guidelines for Frascold's semi-hermetic compressors, specifically designed for use with R410A refrigerant. It covers standard equipment, electric motors, protection devices, lubrication, and refrigerating capacities.

Standard Equipment: The compressors are equipped with suction and discharge valves, rubber vibration absorbers, an oil lubrication charge, and a nitrogen charge to prevent humidity. They also feature an oil sight glass, protection devices, and an integrated differential relief valve. Optional accessories can enhance efficiency and reliability.

Electric Motors: The document details the electric characteristics of motors that operate at 50Hz or 60Hz. For different voltages, consultation with the technical department is recommended.

Protection Devices: Compressors are safeguarded by PTC thermistors in the motor stator, linked to a KRIWAN INT69 electronic control module. Additional high-temperature protection for discharge gas is available for Q and S series compressors.

Lubrication: Lubrication is achieved through centrifugation using an oil thrower disc.

Refrigerating Capacity: Capacities are calculated under specific conditions: 50Hz power supply, no liquid subcooling, ambient temperature of 32°C, suction gas temperature of 20°C, and suction gas superheat of 10K.

Technical Data: Detailed tables provide technical data, including displacement, electric motor specifications, and refrigerating capacities across various operating conditions.

Dimensional Drawings: Dimensional drawings are included for installation and maintenance, detailing various plugs and valves.

Specifications: Specifications for the Q and S series models include key dimensions and measurements in both inches and millimeters for components like suction and discharge valves, base mounting, and overall dimensions.

Components and Features: The document lists components such as suction and discharge valves, high and low-pressure plugs, oil charge and drain plugs, oil level sight glass, crankcase heater seat, and sensor plugs, with descriptions of their functions and measurements.

Procedures and Recommendations: While specific procedures are not detailed, the document emphasizes the importance of correct installation and maintenance of components to ensure optimal compressor performance.

Standards and Norms: The use of R410A refrigerant indicates compliance with industry standards for refrigerants in semi-hermetic compressors.
