I had purchased another chiller before buying from Penguin Chillers. That chiller could not withstand the work load I put on it. After researching I found Penguin Chillers and purchased my first 1 HP Chiller from them. The performance was so good that I purchased a second one to increase my efficiency. They have gone above and beyond to help with the issues I was having with anodizing and chilling. They worked diligently to find the materials that could withstand the heavy duty work of anodizing. They respond very quickly and care about their customers satisfaction. I highly recommend Penguin Chillers and will continue to purchase from them in the future.
