I. Outstanding Energy Efficiency Performance, Significantly Reducing Operating Costs
Danfoss compressors utilize advanced scroll and variable frequency technologies, achieving an energy efficiency ratio that is more than 12% higher than traditional piston compressors. Under the same cooling capacity conditions, power consumption can be reduced by 10%–15%, directly saving users significant electricity costs. The variable frequency scroll compressor VZH series employs permanent magnet motors and intermediate discharge valve technology, enabling the highest efficiency across the entire operating range, with energy-saving effects reaching up to 35%.
II. Excellent Reliability, Ensuring Long-Term Stable Operation
Danfoss compressors feature high-strength cast iron bodies and precision machining processes. The built-in motors use special insulation materials and vacuum impregnation processes, providing excellent heat and moisture resistance. Scroll technology significantly reduces moving parts, eliminating vulnerable components such as suction and discharge valve plates. This results in minimal mechanical wear, extremely low failure rates, and a design life of up to 15 years. Even under extreme operating conditions, stable performance is consistently maintained.
III. Leading Technological Innovation, Meeting Diverse Needs
Danfoss holds multiple core technology patents, including IDV (Intermediate Discharge Valve) technology, variable-frequency air conditioning oil control systems, and triple anti-refrigerant backflow design. The product line covers a wide range from 3 to 450 refrigeration tons, utilizing scroll and Turbocor oil-free technologies. This makes them suitable for various applications such as commercial refrigeration, commercial air conditioning, heat pump systems, and industrial refrigeration. Evaporation temperatures can cover a wide range from -45°C to 7°C, offering multiple capacity adjustment methods, including fixed-speed, digital scroll, and variable frequency options.
IV. Environmental Sustainability, Aligning with Future Development Trends
Danfoss compressors use low-GWP refrigerants (such as R32, R1234ze, R513A, etc.), with an ODP of 0 and a GWP only one-third that of R410A, meeting mid- to long-term environmental regulations. The products have obtained international certifications such as ETL, CE, and PED, comply with ECO design directives, and can directly reduce CO₂ emissions by up to 99.6%.
