2S-H

Product catalog summary

Introduction
The document introduces a new range of two-stage semi-hermetic compressors derived from the existing H compressor range. These compressors are available in 4 and 6 cylinder versions and include integrated liquid subcoolers. They offer displacements from 56 m³/h to 122 m³/h in the low-pressure stage and motor power ranging from 15 HP to 40 HP. The design allows the compressor body to operate at intermediate pressure, reducing the need for external pipes and potential leakage points.

Application Limits
The compressors are optimized for use with R404A and R507 refrigerants, with evaporation temperatures between -75°C and -20°C.

Technical Data
Detailed specifications are provided for various models, including displacement, number of cylinders, suction and discharge dimensions, and net weight. The compressors feature a compact design, optimized low/high-pressure volume ratio, high COP levels, low sound emissions, and minimal pressure pulsations.

Accessories
Standard accessories include motor protection modules, oil differential pressure switches, crankcase heaters, liquid subcoolers, filters, solenoid valves, expansion valves, and non-return valves.

Performance Data
Performance data is provided for different operating conditions, including suction gas temperature and liquid subcooling at the condenser outlet, in accordance with EN12900 standards.

Overall Dimensions
The document provides information on the overall dimensions of the compressors, highlighting their compact design and reduced footprint.

Specifications
The document details specifications for various refrigeration equipment models, including power input (P) in kW and refrigerating capacity (Q) in W. Models such as 2S-H5, 2S-H3200L, and 2S-H3500 are listed with specific power and capacity ratings.

Procedures and Components
The document outlines components and their functions, such as oil sight, oil charge plug, low and high-pressure taps, oil drain plug, and crankcase heater, which are crucial for operation and maintenance.

Dimensions
Overall dimensions for different models are provided, including length, width, height, and inlet/outlet diameters. For instance, the 2S-H1500L model measures 815 mm in length, 572 mm in width, and 456 mm in height.

Standards and Recommendations
Recommendations for installation and operation emphasize adhering to specified dimensions and component functions for optimal performance and safety.
