Colleges often have RC dryers for large student classes. The prints go in soaking wet and emerge only seconds later bone dry. The throughput is amaxing but unless you were running a commercial service printing on RC paper, they are overkill. They take a lot of power and need a few minutes to warm up to operating temp so very expensive for just a few prints. The heat output is large too. I wouldn't like to run one in a small darkroom without having the doors open.
