I had a chiller go out on my 50 gallon Sea Water vision tank so I called Penguin Chillers Customer Support. After talking with them I knew this was the company to do business with. I replaced my broken chiller with their 1/2 HP Water Chiller. It was a bit larger because of the case it’s in and inlet outlet orientation so I just added a 2×4 frame where the doors go and reattached them. Its perfect and it has been running flawlessly for over a year now and was half the price of a replacement chiller from Sea Water.
