Danfoss Compressors: A Legacy of Excellence
The renowned Danfoss compressors, originally pioneered by Maneurop, have been at the forefront of refrigeration technology since 1971. Maneurop initially specialized in manufacturing hermetic reciprocating (piston) compressors, setting a standard for reliability and efficiency in the industry.
In a landmark move in 1992, Maneurop became the first European company to introduce scroll compressors, marking a significant advancement in compressor technology. The following year, in 1993, Danfoss acquired Maneurop, leading to the rebranding of its compressors as Danfoss compressors.
The acquisition propelled Danfoss to the forefront of the refrigeration market, with a commitment to innovation and excellence. In 2001, Danfoss unveiled its groundbreaking achievement: the release of the largest scroll compressor in the market, boasting a remarkable capacity of 25 tons.
Today, Danfoss continues to lead the industry with its cutting-edge scroll compressor models. These compressors exemplify unparalleled performance and versatility, capable of reaching temperatures as low as -40 degrees Celsius in select capacities. With a legacy of innovation and quality craftsmanship, Danfoss compressors remain a trusted choice for refrigeration solutions worldwide.
Danfoss compressors, available in hermetic or closed type configurations, encompass two distinct models: the piston compressors, which include the MT, MTZ, and NTZ series, and the scroll compressors, comprising the S and H series for air conditioning and the MLZ and LLZ series for refrigeration applications. These compressors serve as integral components in refrigeration and ventilation systems, offering a comprehensive range of technical specifications to meet diverse industry needs. Boasting varying capacities, exceptional efficiency, and renowned reliability, Danfoss compressors ensure optimal performance and energy savings. Their quiet operation, particularly exemplified by the scroll compressors, makes them suitable for noise-sensitive environments. While pricing may vary depending on model, capacity, and features, consulting with authorized distributors or retailers is recommended for accurate pricing information. In evaluating the cost-effectiveness of Danfoss compressors, factors such as energy efficiency, reliability, and suitability for specific applications should be carefully considered, reaffirming their status as a trusted choice in the industry.

Danfoss Compressor Nameplate Reading
The method of naming Danfoss compressors involves a combination of numbers and letters, offering valuable insights. Prior to purchasing a Danfoss compressor, it’s beneficial to understand how to interpret its nameplate. Below, we outline how to discern the power of a Danfoss compressor from the nameplate, along with other pertinent technical details provided by the model number.
According to the figure above, we interpret nameplates from left to right as follows:
– “MT” signifies the Danfoss compressor series or type, indicating a hermetic piston compressor.
– The letter “Z,” if present, denotes the type of oil charged in the compressor. In this case, it indicates polyester oil suitable for use with gases such as R-404a and R-134a. Absence of the letter “Z” indicates mineral oil compatibility, typically used with R-22 gas.
– The number “64” represents the nominal capacity or power of the Danfoss compressor in KBtu/h. Dividing this number by 12 converts it into tons of refrigeration. For instance, the given model represents a Danfoss compressor with a nominal capacity of 3.5 tons of refrigeration.
– The number “4” following the model number denotes the required voltage and frequency of the Danfoss compressor motor.
– The letter “V” indicates the presence of an oil equalizer port and oil glass site.
– The letter “I” at the end signifies whether it is a single or bulk (industrial) order.

Danfoss Compressor Selection
To select the appropriate Danfoss compressor for your refrigeration system, you will need to consider several factors including the refrigeration capacity, evaporator temperature, condenser temperature, and refrigerant type. Here’s a general guideline on how to go about selecting the compressor:
- Refrigeration Capacity: Determine the required refrigeration capacity for your system. This is usually measured in kilowatts (kW) and represents the amount of heat that needs to be removed from the refrigerated space.
- Evaporator Temperature: Determine the desired evaporator temperature for your system. This is the temperature at which the refrigerant absorbs heat from the refrigerated space. It is typically measured in degrees Celsius (°C).
- Condenser Temperature: Determine the desired condenser temperature for your system. This is the temperature at which the refrigerant releases heat to the surrounding environment. It is also measured in degrees Celsius (°C).
- Refrigerant Type: Identify the type of refrigerant that will be used in your system. Different refrigerants have different properties and performance characteristics, so it’s important to choose a compressor that is compatible with the refrigerant being used.
Once you have gathered this information, you can refer to the Danfoss compressor catalog or use the Danfoss Coolselector software to select the right compressor for your application. The catalog or software will provide information on the various Danfoss compressors available, including their capacity, operating characteristics, and compatibility with different refrigerants.
When selecting a compressor, be sure to choose one that meets or exceeds the required refrigeration capacity for your system, and that is suitable for the operating conditions (evaporator and condenser temperatures) and refrigerant type being used. Additionally, consider factors such as energy efficiency, reliability, and ease of maintenance when making your selection.
