COMPASS

  • COMPASS (Danfoss Alternative Selection Software) is a software program that helps you to find the best Danfoss alternative for compressors and condensing units for replacement. The purpose of COMPASS is only to provide a comparison with competitor products.

    Select Compressors to find the best Danfoss compressor alternative for the existing model. Select Condensing Units to find the best Danfoss Condensing Units alternative for the existing model.

    Please use the link below to load the compass application in a new window.

     

  • Software Guidelines

    Please note that all values calculated and components selected by this software must be verified by the user. The user must also ensure that installation conditions comply with professional standards and legislation before making a selection.

    2. Guide to Brand Names

    The following brand names have been grouped as follows:

    Danfoss                      Maneurop / Danfoss
    Tecumseh                  Unité Hermétique / UH / Tecumseh
    Unidad hermetica         => Electrolux => ACC => Huayi Compressor Barcelona => Cubigel

    3. Criterion to Define a Danfoss Alternative

    Application – Compressors / Condensing Units
    Refrigerant – Compressors / Condensing Units
    Manufacturer – Compressors / Condensing Units
    Electrical data – Compressors / Condensing Units
    Technology (Hermetic or Scroll) – For Compressors
    Type (Package or Standard) – For Condensing Units

    Compressors with a scale of +10% or ±20% in the cooling capacity may be proposed as best matching alternatives.

    Condensing Units with a scale of –5, + 15% or ±20% in the cooling capacity may be proposed as best matching alternatives.
