Marine Refrigeration Excellence

COOLBLUE cold plate cooling systems are as reliable as your land-based 120v kitchen refrigerator while using half the daily amps of other 12v refrigeration systems. Utilizing the latest technology in variable speed compressor design, low amp 12v fan, an oversized condensing coil, and holding plate with preset expansion valve. 

The COOLBLUE cold plate cooling system operates simply and efficiently, eliminating the complexity and excess power associated with water-cooled systems. While other 12v systems require water cooling at temperatures above 90F, COOLBLUE operates at ambient temperatures up to 120F without losing system efficiency or thermal management

Hear from Our Satisfied Customers

I commend you for your commitment to your product and your customers. I have never regretted getting an AC system after talking to you. Many friends run their 12 volt units for several hours to fill the tank, while monitoring/augmenting battery amps. That is a lot of wear on the components for a little water. I never run mine for more than an hour, getting the amps from the main engine, my Honda generator, or shorepower. I have made more than 1000 gallons of water so far, with only 37 hours of run time.

I want to thank you for all your help with my Cruise RO Water SeaMaker 20 water maker. We assumed our only option was a 12v water maker but they were more expensive and could only produce a disappointing 6-8 gallons. We determined that with a 2000 watt inverter we could make water while underway and with the little Honda 2000 genset we had ample power to make water at anchor. I had always heard that watermakers were a pain to maintain and operate but with easy to read well laid out instructions it is a breeze. I love my water maker and the 21 gal per hour that it actually produces fills my tanks quickly with the best water I have ever tasted.
Nick Chiappini
I cannot say enough about CruiseRO and the customer service they provide. I installed a sea maker 40 in my Jeanneau 54DS and upon startup I noticed I had a feed problem to the high pressure pump. I contacted Charlie, and he built a mockup of my system to discover I needed a larger output low pressure feed pump and 3/4″ feed lines. He tested it before shipping, then sent an overnight package with everything needed and labeled as to where it was to be installed in the system. After two hours I was making water. This is one incredible company.
