TANDEM Semihermetic Compressors

Product catalog summary

Technical Specifications
The document details the technical specifications for the T-HI series of semi-hermetic motor compressors, including displacement volume, suction and discharge dimensions, oil charge, net weight, maximum operating current, and locked rotor current for models such as TH 35, TH 41, TH 5, TH 6, and TH 7.

Key Features
Each compressor model includes components like an oil sight, oil charge plug, low and high-pressure taps, oil drain plug, crankcase heater, and service valves for discharge and suction, essential for operational efficiency and safety.

Compressor Range
The document highlights the range of compressors, emphasizing the benefits of inverter technology. Tandem compressors operate with one compressor using an inverter and the other in a standard on-off mode, ensuring pressure and lubricant equalization across various speeds and conditions.

Electrical Connection
Proper electrical connection setup is crucial for optimal performance and safety of the compressors.

Overview of T-HI Compressor Range
The T-HI compressor range by Dorin is discussed, focusing on the advantages of inverter technology and the TANDEM configuration, which pairs a standard compressor with an inverter-driven compressor.

Specifications and Features
T-HI compressors feature enhanced suction joints for lubricant and pressure equalization, and a common discharge line with a check valve on standard compressors. Electrical connections differ between HI and STD compressors, with HI using a delta connection and STD requiring a 400 V power supply.

Performance Calculation
The cooling capacity is calculated by summing the capacities of both compressors when the STD compressor is operational. If the STD compressor is off, the capacity is determined by the HI compressor alone. Examples illustrate performance under different conditions.

Technical Data and Model Selection
A table lists various T-HI models, their specifications, and performance data under different conditions. An example selection process for a specific refrigerant and temperature scenario is provided to demonstrate model selection based on cooling capacity requirements.

Key Components
The document outlines technical components such as oil sight, oil charge plug, pressure taps, and service valves, offering a comprehensive understanding of the compressor's construction and functionality.
