How we Installed our New Frigoboat System
Last Updated May 1, 2017
Why We Upgraded
We had a perfectly good, working refrigeration system (details here). With spares and tools and the knowledge to keep it running for years. So, why did we rip it out and upgrade to a Frigoboat system? The biggest issue was that the holding plate system compressor drew 40-45 amps when it ran. This is a heavy draw, and unless we had a charging source putting at least 20 amps IN to the batteries at the same time, it would draw the voltage down. This is bad for the batteries, and it meant that we couldn't leave the boat with the refer on "automatic". The big compressor system worked well when we were moving every day, or tied to the dock. But out on the hook, not moving as much, and with solar power as our primary source of power, it became a pain to manage.
Other side-benefits:
1. Removing the holding plates gave us quite a bit more usable space in the freezer.
2. The temperature is more evenly controlled, so frozen stuff stays better.
3. The tiny Danfoss compressors are so quiet that you hardly notice them running.
What we bought
We have a large refrigerator space and a fairly large freezer space. So after researching the appropriate replacement system from Frigoboat, here is what we bought (Nov 2010).
| Qty | Description | Part No | List Price (ea) |
| 2 | K50-SSC with Smart Speed Control | E51975SSC | $1,022 |
| 2 | Keel Cooler stud-mounted condenser with zincs | E50722Z | $660 |
| 2 | 200F Evaporator - 40.25"w x 10.5"h, Flat Plate | E50075 | $295 |
| 2 | Thermostat, Coastal Digital Fahrenheit 12v | CFAH12 | $125 |
| 1 | Thermostat, Refrigerator Mechanical | E250500 | $38 |
| 1 | Thermostat, Freezer Mechanical | E250700 | $38 |
| 8 | Spare Zincs for Keel Cooler | E51525 | $8 |
At the time of purchase, Frigoboat had just announced that it was discontinuing its 'Smart Speed Control' due to extremely high manufacturing costs. We were urged to buy the Danfoss version of the Speed Control instead (the AEO). We went ahead and bought the SSCs, but could not get a spare SSC due to availability. We have bought a pair of AEO's for spares, from Mechtronics, instead.
