For the past 30 years I designed and built hydraulic driven transport refrigeration equipment for the commercial fishing industry. During those years, I also worked on a design for a full sized transport unit for semi trailer application. The trailer unit, a converted Transicold Ultra, was tested in actual use for a year before it was removed from service. I have tried, unsuccessfully, to find funding to continue the development of the manufacturing prototype and wish to make the engineering available to a company that would produce the units. At present, I have invested over 1.5 million dollars (US) and a value on the completed engineering and testing valued at around 10 million dollars. I would be willing to work on a salary basis with a royalty on sales as my future return on investment. In addition to the full size trailer unit, I have worked on a design for the smaller straight trucks that utilize many of the same parts which in turn provides a line of transport units from 5 hp to 25 hp of actual cooling or freezing capacity. Temperatures of –40 F can be achieved if desired with –25 F being the normal low temperature setting. I have enough cast and machined parts to complete 50 compressor sections. The evaporators and condensers have been designed and tested with readily availability for manufacturing. The frames are to be built from 6061 marine grade aluminum. The only part yet to be built is the outer housing. I have a few designs in mind but haven’t needed to go beyond the design stage. The avatar shows a completed hydraulic compressor. The weight of the 20+hp compressor section is less than 100 pounds.

The hydraulic driven units utilize a variable volume hydraulic pump on the truck or tractor engine. The minimum operating engine RPM is 800. The maximum engine RPM is 3,500. Between these two operating limits, the pump provides enough power to maintain maximum cooling capacity on all the units. The only difference is the size of the pump and motors between the smaller units, 5 to 7.5 hp and the larger 10 to 25 hp units. The hydraulics do not have the high efficiency loses of diesel or electric. The actual energy transfer is about 95%. The weight of the hydraulic units is about ˝ of the standard units available from Thermo King and Traniscold. The maintenance on the hydraulic units is reduced to changing one belt and one filter once a year. The yearly fuel saving alone will normally cover the cost of the unit.

If you or your company finds any of this interesting, I can supply a lot more information prior to entering into any formal agreement. If you know of anyone who might be interested in this type of venture, please relay this to them. The transport market is in excess of 2 billion dollars per year and this unit design has been studied with a conclusion that it would achieve 80+ % of the market within 6 years. This may sound too good to be true but I am now retired and don’t want to see all my effort go to waste.
