THE "WORLD CLASS" REMANUFACTURING PROCESS
All World Class RV Refrigeration, Inc. cooling units undergo a complete
"remanufacturing" process that involves several steps to produce one of the
finest units available on the market today.
First, all cooling unit cores are carefully inspected to ensure that they meet
our strict standards for quality before they are disassembled for a rebuild.
After the cores are selected, they are first pressure washed to remove any dirt
and chemicals that accumulated over the years, and the old foam pack that
surrounds the evaporator is removed. Then, the evaporator and boiler sections
are cut from the unit.
Next, the evaporator and
boiler sections are replaced with the new sections.
This way, we have little doubt that you will enjoy the same service that your
original cooling unit provided for so many years. And, this is the only way that
we can offer the type of warranty that comes with each of our units. During this
process, both sections are welded in a "jig" that mimics the exact dimensions of
the refrigerator that the cooling unit is intended for. This allows for a very
trouble free installation on your part, as everything will just slip into place.
We even go to the extent of placing the correct gas burner into the unit when
the boiler section is welded into place. Just another quality control step that
we have in place to ensure the proper fit into your existing refrigerator box.
And, our welder has over 12 years of experience, holds over 15 welding
certifications including high pressure steam boilers like those found in nuclear
power plants and submarines, and is ASME and AWS licensed. I promise that you
will find no better welder on staff at any other company that performs the same
service that we do.
After the boiler, evaporator, and small lines are replaced, the units are
completely flushed for contaminants. At this time, they are also checked for any
blockage in the lines that might prevent full circulation throughout the unit.
The units are now ready to be charged with the ammonia solution. The solution is
first introduced into the cooling unit, the unit pressurized slightly, and all
new welds are sprayed with a special leak detector as a last precautionary step.
The unit is then drained of the initial ammonia solution to check for the proper
concentration of chemicals, as some residual water may still be in the unit from
the contaminant flush. Even the slightest variance in concentration levels might
keep your new unit from providing it's maximum cooling effect. The adjusted
solution is then placed back in the unit, and it is pressurized. Please note
that these units are under a great deal of pressure, and should not be
discharged by anyone other than an experienced service technician.
After charging, the units are hooked up and allowed to operate for several hours
in order to check their cooling capacity. Any unit that does not pass this test
is rejected, and the charging process starts over. No unit is shipped without
undergoing this test.
The next step in the process is simple.....paint. Several coats of high quality
paint are applied to the unit, both for aesthetics and for performance. While we
want our units to look as good as they perform, the paint will obviously keep
rust from forming on the unit, thus extending it's operational life.
The units are then placed on our foaming board to receive a new foam pack around
the evaporator. This serves a few purposes, one of which is to help insulate the
evaporator from the condensation that forms as a part of the absorption process.
This is the real enemy of the cooling unit. The condensation settles around the
outside of the evaporator, which over time forms surface rust, that leads to
more rust, and so on. After a while, the structural integrity of the tubing
deteriorates to the point that the pressurized ammonia bursts the tubing. This
is the cause of the ammonia smell that signals the death of your cooling unit.
Our foaming molds are duplicated from actual refrigerator boxes, thus assuring
that each foam pack will fit the refrigerator it was intended for. However,
please note that some minor trimming of the foam pack might be necessary.
After all of this, each new cooling unit is assigned a serial number for
tracking and warranty purposes.
Key Benefits
- Every WCRVR cooling unit is fitted with a new galvanized evaporator head
assembly instead of "patching" the leak in the old, rusted evaporator.
- Every WCRVR cooling unit has a new boiler assembly.
- The lower cost and ease of installation allows you to save
literally hundreds of dollars by doing the work yourself.
