Our Nova Kool refrigerator common to most NT37’s was replaced with a similar unit in 2018. Following commissioning this year, the lowest temperature reading is 40-42 degrees with readings climbing into upper 40’s with higher ambient temperatures and humidity. I installed a muffin fan behind the unit several years ago but that does not appear to be making the situation any better. Are there other owners who have faced this issue and what have been their recommendations/solutions? Are there other makes with better results that would be a perfect fit dimension-wise?

We replaced our NovaKool on our 37 with a Vitrofrigo. It keeps perfect temps no matter the environment (I keep it on while sitting at our dock in VA when temps can reach into the high 90s). I bought it from Defender and was delivered in great shape. B.

i second the suggestion to switch to Vitrifrigo. We were mever happy the performance of the NovaKool in our 2006 42-078 and changed out for a Vitrifrigo with the reference on top and pull out freezer bin on the bottom. The Vitrifrigo works great and consumes less energy. it should work well, considering it costs about 3x that of a NovaKool. IIRC, Vitrifrigo is now the standard for both American Tug and Nordic Tug.

We have the original Tundra on our 37-100. I was about to replace with Vitrofrigo model last year until I found a marine refrigerator technician that came to my boat, replaced two of the key components and my refrigerator was like new for 30% of the price of the new one. Just a thought.

Hey Brian! What was the hull number on your 37, and what model Vitrifrogo was a fit? Did your 37 have the stacked fridge/freezer, or the separate units? Thank you!
