A condenser coil for a refrigerated beverage and food service merchandiser includes a plurality of parallel fins or V-shaped fins between 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 coil includes a plurality of flat multichannel tubes, with no fins therebetween, and the spacing between the multichannel tubes is maintained in the range of 0.4 to 0.8 inches. In one embodiment, the coil includes at least one serpentine shaped, multichannel tubes, with no fins therebetween, and the spacing between flat, parallel segments of the multichannel tubes is maintained in the range of 0.4 to 0.8 inches.
