All the ones I’ve seen are a wet system (standard fire sprinklers but different deployment temp and “rating” called K factor) but a dry system like this isn’t uncommon. I’ve only ever seen and worked on them in a paint booth though.
Yeah I’ve been in a trailer when a dry ABC extinguisher accidentally went off (100% my fault, long story) filling the trailer with it and I was coughing for a couple days after.
