Here's what/Why we do what we do...
I started out as a one person on-site service tech. One day a good customer had a new brand of unit no one had ever seen before and asked if I could work on them. I said yes, but they are brand new and I would not be able to cover the warranty myself. I would see if I could get authorized by the nearest dealer. which turned out to be in Miami. We set up terms for these repairs and by the third one the factory called me and invited me to be a sponsored dealer of this brand of refrigeration. I agreed, and tried to start to sell this brand as a refrigeration dealer only. meaning I outsourced the truck insulation. IF and when these guys did not under cut me for the deal, we got back a great looking box sprayed into the van. The problem was they would not cool very well or the unit would never shut off, struggling to keep temp with 3 inches of insulation. I was told to buy/sell 4 inches of insulation or use the next size unit up. Both options added between 1500 and 3000 dollars to the build.
Thinking I could bypass this cost (because the actual material costs were like a dollar a square foot ) I bought my own spray in liner system at a cost of 30K thinking if I did 10 it would pay for itself. What I found was the reason for the $1500 to $3000 was they were spraying double the insulation to get basic temps that in truth,almost 8 inches was needed for frozen and that is why they do not offer true frozen packages. Not only that , but the foam absorbed water like a sponge and turned into black mold. After we did 6 units I retired the machine.
Upset by this, I started researching insulation, heat and the science behind heat transfer. I also researched out the best materials using government testing data the military conscripted for insulation of their food stores on ships and in the desert. Turns out not all insulation is the same. Even if most of it is sprayed with the same machine. 90% of my competitors are using what amounts to attic foam insulation, which is literally designed to hold and absorb a given amount of heat. That was why inches of this insulation was not enough to use a small unit to keep a small van cold on a very hot day. What was happening was 2/3 of the insulation was holding heat while 1/3 was trying to keep the cold in the box. That is why we had to use double the foam product.
How we differ? We use a series of radiant and convective purposed heat shield as a barrier between the skin of the van and the insulation core and we use high density closed cell refrigeration grade foam (not poly styrene as according to the department of the navy it off gasses and after 5 years when this off gassing is complete it looses up to 30% of it's cooling capacity.) meaning if you bought a truck 5 years ago and it cooled great, but now it struggles and your tech says there is nothing wrong with the unit... the foam has degradation. The foam we use is almost double what most builders pay but it is good for 25 years. 1 inch of this foam has the R value equivalent of 2 inches of most spray in foams. Remember, our foam is compressed when layed out into large blocks while spray in foam is allowed to expand. Most spray in foams are trapped air and gas from the chemicals of the foam. Couple the best refrigeration foam available on the market with heat shield and the heat shield keeps most of the heat out of the box completely (I have pic of a 100 + degree day, and in a typical van the skin roof panel of the van was over 130*F and just with the paper thin radiant heat shield the temp dropped over 30*F. the heat shield alone removes more heat, than the typical spray in liner)
and our foam can use its total make up to keep the cold in.
We were told a temperature drop of one degree a minute with a raised 1800 rpm idle was normal. 2 degrees a minute was good when you oversized a unit.
We average between 4 and 6 degrees a minute on a hot day with an average size unit.
We sell the only units I know of (and we fix a lot of other competitors up fits) that can offer a true -20F on a van without having to default to the largest most expensive system on the market. ALL At A Price Equal to or usually far less than our competitors. Why? Because we do not have to out source any of the build. We are a licensed car dealer who buys wholesale at the dealer auction, that saves you car dealer fee and mark up. We are a licensed refrigeration dealer as well which saves dealer fee and market/installation, and we are the insulation up fitter which again, uses better product but often times costs the same. So rather than being hit by three separate companies, each having to mark up the project van build to just stay in business, we mark up the build once usually a 1/3 of what a build normally would cost.
Yes others advertise at or lower but if you read the small print or speak with them this is a base price and if you want 'extras' like insulation or a refrigeration unit it cost more!
