Introduction
The document introduces the new aluminum compressor range by Dorin, specifically the HAL series, designed for transport applications. These compressors are optimized for new refrigerants, focusing on energy efficiency, reliability, and low noise levels.

Specifications
The HAL range consists of 4-cylinder compressors derived from the H35 and H41 series. Key specifications include:

• Displacement range: 19.29 to 63.66 m3/h
• Nominal power: 4.5 to 22 hp
• Weight reduction due to aluminum construction
• Compatibility with refrigerants: R404A, R134a, R407C, R507
• Standard IP65 electrical box
• Same dimensions as H35 and H41 compressors

Features
The HAL compressors offer several advanced features:

• Significant weight reduction for rooftop applications
• Variable speed operation over a wide frequency range
• High Coefficient of Performance (C.O.P.) due to optimized fluid dynamics and high-efficiency motors
• Low noise and vibration levels
• Reduced gas pulsation

Technical Data
The document provides a detailed table of models with specific technical data, including displacement, oil charge, suction and discharge dimensions, and net weight for each model.

Conclusion
The HAL series compressors are designed to meet modern market demands with a focus on efficiency, adaptability, and reduced environmental impact, making them suitable for a variety of transport applications.
