Catalogue SERIES 134-IS

Product catalog summary

Compressor Specifications:
The document details a semi-hermetic refrigerant compressor optimized for R134a, featuring inverter capacity regulation. It includes built-in volumetric ratios with standard and optional configurations. The nominal motor power is specified at 70 Hz.

Model Specifications:
Various models are listed with nominal power ranging from 100 to 420 Hp. Displacement at 70 Hz varies from 378 to 1540 m3/h. Weight, oil charge, and connection sizes are specified for each model.

Electrical and Mechanical Features:
The compressor power supply is compatible with 400 V/3/50 Hz and 460 V/3/60 Hz. Inverter insulation is rated at IP 54. Terminal screw sizes and full load amperage (FLA) are provided for different models.

Performance Data:
Performance metrics are provided for different models at varying frequencies (30 Hz, 50 Hz, 70 Hz) and conditions (T_ev = 2°C, T_cond = 50°C and T_ev = 5°C, T_cond = 38°C). Metrics include cooling capacity (Q0), power absorbed (Pa), and coefficient of performance (COP).

Additional Features:
The document highlights the absence of starting currents, reducing electrical wiring needs. It also lists various connections and components such as suction and discharge lines, oil charge/drain valves, and temperature sensors.
