It's a Pacific Coast Imports 1 HP chiller. A friend bought it around 2 years ago, and I got it from him about 8 months ago with plans of going to a salt tank, but never did. I tested it with the freshwater tank and it works fine.
This thing is pretty large and heavy. It doesn't come with a pump. It has 1" in and out ports, titanium heat exchanger. You can look up all the specs, it's a C-1000 model, no heater.
Somewhat flexible on the price, it's difficult to find these things used to judge how much to ask. $800
