A condenser coil for a refrigerated beverage and food service merchandiser includes a plurality of parallel fins be-tween adjacent tubes. In order to reduce the likelihood of fouling by the bridging of fibers therebetween, the spacing of the fins is maintained at a distance of 0.4 to 0.8 inches apart. In one embodiment, the tubes comprise microchannel tubes, with no fins there-between, and the spacing between the microchannel tubes is maintained in the range of 0.75 inches to optimize the heat transfer performance while minimizing the occurrence of fouling. A supporting structure is provided between microchannel tubes when no fins are included. Also, plural rows of microchannel tubes are provided with separate inlet headings and with the rows being stag-gered in transverse relationship to enhance the heat transfer characteristic while minimizing the likelihood of fouling.
