I. Optimized for Medium- and Low-Temperature Commercial Refrigeration with Superior Energy Efficiency The HRM series is specifically designed for medium- and low-temperature applications such as freezers and cold storage rooms, delivering outstanding energy efficiency. • Exceptionally High Energy Standards: Featuring optimized scroll profiles and high-efficiency motors, this series achieves energy efficiency ratios significantly exceeding market averages, enabling end-use equipment to easily meet EU ERP directives and China Grade 1 energy efficiency standards. • Excellent Part-Load Efficiency: Since commercial refrigeration equipment operates most of the time under partial loads, the HRM series maintains high efficiency under such conditions, resulting in lower annual energy consumption and substantial cost savings for users. II. Top-Tier Reliability Ensures Uninterrupted Operation For applications requiring 24/7 operation, such as supermarkets and cold chain logistics, reliability is critical. The HRM series excels in this regard. • Robust Mechanical Structure: Utilizing high-quality bearings and materials, its durable internal construction withstands refrigerant slugging and system fluctuations, ensuring long service life. • Broad Operating Range: Capable of stable operation in ambient temperatures from -35°C to +45°C, adapting to diverse environments from cold climates to high-temperature kitchens. • Integrated Intelligent Protector: Equipped with a motor protection module that safeguards against overloads, overheating, and other electrical anomalies, preventing damage due to power issues or system faults. III. Low Noise and Vibration Enhance the Shopping Environment The HRM series emphasizes quiet operation, making it ideal for noise-sensitive commercial spaces like supermarkets, convenience stores, and restaurants. • Advanced Scroll Technology: Inherently smooth and stable operation of scroll compressors is fully leveraged in the HRM series. • Optimized Design: Precision dynamic balancing and sound insulation measures ensure minimal operational noise, allowing the equipment to blend seamlessly into quiet shopping environments without disrupting customers. IV. Wide Applicability and Strong Compatibility The HRM series offers multiple models (e.g., HRM032U4, HRM038U4) covering a broad range of cooling capacities, making it highly versatile. • Broad Applications: Ideal for commercial freezer displays, modular cold storage rooms, ice cream storage cabinets, and low-temperature processing equipment. • Strong Refrigerant Compatibility: Fully compatible with traditional refrigerants like R404A and R407C, as well as next-generation low-GWP refrigerants such as R448A and R449A, facilitating easy environmental upgrades without core redesigns. V. Easy Installation and Maintenance • Compact Design: Space-saving structure simplifies integration into equipment layouts. • Standardized Interfaces: Normative design and standardized connections reduce installation complexity and time for system integrators. Summary The core advantages of the Danfoss HRM compressor series can be summarized as: Efficient, Quiet, Reliable, and Adaptable. It is not merely a cooling component but a value-added solution for both commercial refrigeration equipment manufacturers and end-users: • For Manufacturers: Simplifies compliance with energy standards, enhances product reliability, and reduces after-sales service issues. • For End-Users (e.g., supermarket owners): Delivers lower electricity bills, quieter shopping environments, minimized downtime (ensuring product safety), and reduced maintenance costs. As a result, the HRM series is a globally trusted and benchmark product in the commercial refrigeration industry.
