Two Stage Semihermetic Compressors 60Hz

Product catalog summary

Introduction
The document introduces a new range of two-stage semi-hermetic compressors derived from the H compressor range. These compressors are available in 4 and 6 cylinder versions and include a factory-assembled liquid subcooler. They offer displacements ranging from 68 m3/h to 147 m3/h at 60 Hz in the low-pressure stage, with motor duties between 15 HP and 40 HP. The design innovation eliminates the need for external pipes, reducing potential leakage points and overall dimensions.

Application Limits
The compressors are designed to operate efficiently at evaporation temperatures as low as -75°C using R404A refrigerant.

Technical Data
Detailed specifications for various models are provided, including net weight, displacement, number of cylinders, and suction and discharge parameters. For instance, the 2S-H1200L model has a displacement of 67.78 m3/h and a net weight of 193 kg.

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 operation at 60 Hz with liquid subcooling, in accordance with EN12900 standards. The document advises against mixing ester oils with other oils.

Overall Dimensions
Dimensions for each model are specified to ensure compatibility with various installation requirements.

Key Features

Compact design with no external interphase pipes.
High COP levels and low sound emissions.
Optimized low-pressure/high-pressure volume ratio.
Reduced leakage rates and pressure pulsations.

Specifications
The document provides specifications for various refrigeration equipment models, identified by model numbers such as 2S-H5, 2S-H3200L, 2S-H3500, etc. Key parameters include power input (P) in kW and refrigerating capacity (Q) in W, with different temperature conditions listed, including condensing and evaporating temperatures.

Procedures and Components
The document outlines various components and their functions, such as oil sight, oil charge plug, low and high-pressure taps, oil drain plug, and crankcase heater. It provides translations for these components in multiple languages, highlighting their importance in equipment operation and maintenance.

Dimensions
Overall dimensions for different models are provided, including measurements for length, width, height, and inlet/outlet diameters, which are crucial for installation and spatial planning.
