HEP - ECOpremium RANGE R134a

Product catalog summary

Introduction
The document introduces the "ECO PREMIUM" range of semi-hermetic motor compressors by DORIN, optimized for R134a applications. These compressors are designed for enhanced energy efficiency through improved compressor efficiency at low condensing temperatures, high-efficiency electric motors, optimized valve plate dimensions, and fluid-dynamic analysis to minimize pressure drops. They are compatible with inverter drive operation over a wide frequency range.

Complete Range
The "ECO PREMIUM" range serves as an effective alternative to traditional R404A systems, especially for medium temperature commercial refrigeration. Key benefits include reduced operating pressure, increased cycle COP, lower noise levels, reduced maintenance costs, and lower Global Warming Potential (GWP), leading to a short payback period and significant annual cost savings.

Accessories
The document lists available accessories for the compressors, such as motor protection modules, oil differential pressure switches, crankcase heaters, and optical oil level sensors. Some accessories are standard, while others are optional.

Performance Data
Performance data adheres to the European Standard EN12900, providing detailed metrics for different models under various conditions. It emphasizes the importance of not mixing ester oils with other types.

Overall Dimensions
Details on the compressors' overall dimensions are provided, including displacement, oil charge, suction and discharge dimensions, and net weight for each model.

Key Specifications
- Frequency: 50 Hz (with data for 60 Hz operation provided)
- Models: H400EP to H7000EP
- Power input and refrigeration capacity are detailed for each model under various conditions.

Conclusion
The "ECO PREMIUM" range offers a modern, efficient solution for commercial refrigeration, with significant operational and environmental benefits over traditional systems.

Performance Specifications
The document provides performance data for refrigeration units using R134a refrigerant, based on the European Standard EN12900, applicable for 50 Hz operation. For 60 Hz operation, performance values should be multiplied by 1.18. It is crucial not to mix ester oils with other types of oils.

Refrigerating Capacity and Power Input
Detailed tables show the refrigerating capacity (Q) in watts and power input (P) in kilowatts across various evaporating temperatures from +5°C to -20°C, for models such as H700EP, H800EP, H600EP, and others.

Overall Dimensions
The document provides overall dimensions for various models, including length (L), height (H), and other specific measurements in millimeters, crucial for installation and space planning.

Component Descriptions
Key components of the refrigeration units are described, including the oil sight, oil charge plug, low and high-pressure taps, oil drain plug, crankcase heater, and service valves, essential for operation and maintenance.

Contact Information
The document concludes with contact information for Officine Mario Dorin S.p.A., including their address in Florence, Italy, and contact details for further inquiries.
