Danfoss Brushless DC
Hermetic Compressors

  To say that Danfoss is the world market leader in hermetic DC refrigeration compressors borders on an understatement.  In 1977, the company introduced the first of their BD models.  The BD compressors were the first to be designed specifically for refrigerator and freezer use under low-voltage DC power.  The product was an instant success and has since dominated the industry to such an extent that there virtually remain no competitors to this day.  With the discontinuation of the smallest of their compressors (BD 2.0, 2.5 and 3.0), Danfoss now has three models in production - BD35F, BD50F and BD80F. 
 

BD80F

The BD80F is the most recent and most powerful of the Danfoss DC compressors.  The compressor was introduced in mid-2005 and combines over 25 years of experience in a compact and highly efficient unit.  Like the smaller BD35F and BD50F models (below), the BD80F uses an electronically commutated permanent magnet brushless DC motor.  The advantages of this approach are small size, high efficiency and variable-capacity.  Also, as with its predecessors, the BD80F requires the use of an electronic power module.  While the two smaller compressors (BD50F and BD35F) use the same modules, the module for the BD80F is different.  It includes an internal cooling fan (cooling kit 071-0500 is not required) and incorporates a special "Adaptive Energy Optimizing (AEO)" feature.  The AEO feature allows the compressor to adapt its speed to the actual cooling demand resulting in additional energy efficiency.

NOTE:  All BD80F compressors require a Power Module to run.  The module must be purchased separately from the compressor.  The same module is used for 12vdc and 24vdc systems.  For additional technical information, see Danfoss BD80F Specifications and Wiring.

BD50F

The BD50F is second in line to the BD80F compressor.  Like the smaller BD35F (below) and larger BD80F (above), the BD50F uses an electronically commutated permanent magnet brushless DC motor.  The advantages of this approach are small size and variable-capacity.  However, as with its predecessors, the BD50F does require the use of an electronic power module.  Like all electronics, the power module is extremely reliable as long as it is properly installed and does not overheat.  (To prevent overheating use our Danfoss Power Module Cooling Fan Kit.) 

NOTE:  All BD50F compressors require a Power Module to run.  The same power module is used for both 12vdc and 24vdc.  There are two types of modules to choose from, the standard power module (010-1175) or the Adaptive Energy Optimizing (AEO) module (010-1176).  The AEO module is more energy efficient as the compressor will always adapt its speed to the actual cooling demand.  The modules must be purchased separately from the compressor.  For additional technical information, see Danfoss BD50F Specifications and Wiring.

BD35F

With the discontinuation of the BD 3.0 and 2.5, the BD35F is now the smallest of the direct DC compressors.  It has the same features, size and weight as the BD50F and BD80F but has a lower capacity and slightly lower efficiency.  Because of its lower capacity, it is the preferred replacement for existing systems using the older compressor models.  All BD35F compressors require the use of an electronic power module.  As with the BD50F, the power module is extremely reliable as long as it is properly installed and does not overheat.  (To prevent overheating use our Danfoss Power Module Cooling Fan Kit.)  

NOTE:  The BD35F and BD50F use the same electronic power modules.  The same power module is used for both 12vdc and 24vdc.  There are also two types of module to choose from, the standard power module (010-1175) or the Adaptive Energy Optimizing module (010-1176).  The AEO module is more energy efficient as the compressor will always adapt its speed to the actual cooling demand.  The modules must be purchased separately from the compressor.  For additional technical information, see Danfoss BD35F Specifications and Wiring.

Danfoss Power Modules
For Older (4-Pin) Compressors.

Feb. 19, 2003 - Danfoss has discontinued production of all 4-pin modules.  Owners of older 4-pin compressors will need to replace both the module and compressor with either the BD35F or BD50 above.

If you own one of the thousands of small DC  refrigeration systems built over the past 25 years using a Danfoss compressor with a 4-pin Power Module connector, these are the modules you need.  Unlike the newer (3-pin) modules, these old-style modules do not automatically compensate for different voltages.  Be sure to select correct one for 12v or 24v use.

These modules are Danfoss Part  #102N3030 (12v) and #102N4030 (24v).  They are the newest design and replace all other 4-pin modules.

For additional technical information on this module, see Danfoss 4-pin Module  Specifications and Wiring.
