DIY System Kits

Chances are that at any given time, in any given anchorage around the world, there is a boat with a malfunctioning refrigeration system.  Why has it not been fixed?  Because few people have the expertise needed to make repairs.  Refrigeration is widely considered a "black science" but the principles are actually quite simple.  The best way to master refrigeration is by taking it head on and building your own system.  In building your own system, you gain the knowledge and experience needed to repair not only your own system, but those of others as well.  You will know exactly what is in it and how it works. 

RParts has acquired the services of one of the top refrigeration specialists in the marine industry to develop a line of do-it-yourself (DIY) refrigeration systems.  These systems are designed for those who are hands on and enjoy building it yourself.  Taking this hands on approach not only serves as a lesson in basic refrigeration 101 but there is also the added benefit of saving money.  Our kits are priced significantly lower than that of name brand systems with a savings of up to 40%.

All systems can be assembled easily using the components and comprehendible assembly and installation manuals.  Once completed, your system will match or surpass the performance of all the name brand systems.  Limited warranty is offered for all kits.  See the DIY Kits warranty for details.

System 1M is perfect for converting an icebox to a refrigerator/freezer box.  It includes the industry standard Danfoss BD50F, 12/24V compressor and a freezer roll bond evaporator box.  This system can be improved in energy efficiency by upgrading the compressor power module.  With a module upgrade (1M-O1) to an Adaptive Energy Optimizing (AEO) module (010-1176), the compressor will to adapt its speed to the actual cooling demand.  

With adequate insulation (3" minimum), this system configuration gives you up to a .45 cu ft freezer and up to 8 cu ft refrigerator.  With an evaporator box upgrade (1M-O2) to a larger box (019-0350), capacity is increased and will give you up to a .70 cu ft freezer and up to 12 cu ft refrigerator. 

We have assembled the kit using parts available through RParts.  See the complete 1M parts list included with this kit.  See the complete tools list to view the required tools needed for assembly and installation.  You may want to get one of our refrigeration books to help you design your box and system.  We recommend "Refrigeration for Pleasureboats" by Nigel Calder.

Kits are easy to put together with limited mechanical and soldering ability.  We have put together an extensive assembly and installation manual for your use.  Take a look at the manual and contact our DIY Support Forum if you have any questions. This forum is dedicated to support our system customers. Feel free to share your experiences and get the assistance you need.
