These are milk refrigeration units and cup heating racks that are WMF products made to go with WMF machines. While they can be used with ANY machines, their dimensions are tailor-made to pair well with WMF Bistros and WMF 1400s. In addition, some of the units had colored lighting that will match the lighting of your WMF Bistro and/or WMF 1400 to set a striking decor.
Below, we've separated the systems into those that are just milk refrigerators, those that are just cup heating racks, and the compound systems that do both. Note that the milk refrigerators can be ordered to have TWO milk outputs to be used with the WMF Bistro that has two milk inputs.
