Does anyone make an A/C larger than 15,000 BTU

Dometic makes a marine version of an 18K BTU AC with almost the same footprint, weight, and power consumption of a 15K. The difference is that these units are water cooled and I don't know if the size of an air cooled condenser at that size would be problematic. I would certainly be leery of the Chinese knock-offs that claim to do more for less.
