1. Product Overview This series consists of hermetic scroll compressors specifically designed for medium- and low-temperature commercial refrigeration and air conditioning applications (for certain models). As part of Danfoss' high-performance scroll compressor platform, the series is renowned for its exceptional energy efficiency, wide operating range, and robust reliability.
Technology Type: Scroll Technology
Construction Type: Hermetic
Application Scope: Commercial medium- and low-temperature refrigeration, cold storage and freezing, heat pumps, and specialized air conditioning systems
2. Core Features & AdvantagesAdvanced Scroll Technology:
Optimized scroll profile design ensures highly efficient and smooth compression, delivering exceptional volumetric and isentropic efficiency.
Extremely low vibration and noise levels enhance end-user experience and reduce stress on the system.
Outstanding Energy Efficiency:
Designed to comply with global energy regulations (e.g., EU ErP directives), these compressors often meet or exceed efficiency classes (e.g., IE3, IE4). Optimized internal design significantly reduces operating energy consumption, lowering lifecycle costs.
Wide Operating Range:
Suitable for both medium- and low-temperature applications, with broad adaptability to varying evaporation temperatures. Enables flexible use in diverse scenarios, from display cabinets to freezing warehouses.
Robust Motor and Protection System:
Equipped with high-performance, durable motors and built-in PTC thermistors and internal overload protectors. Effectively safeguards against damage from overheating, overcurrent, or voltage instability, ensuring long service life and operational reliability.
Optimized Internal Structure:
Forced oil return system ensures reliable lubrication under all operating conditions, enhancing compressor reliability and suitability for long pipelines and large height differences.
Primarily compatible with environmentally friendly HFC refrigerants such as R404A and R134a, widely used in global commercial refrigeration applications.
