Is this "our" Fabrication Group?
HEAT TRANSFER INTERNATIONAL (HTI), formerly PRESQUE ISLE
ENGINEERING
HTI specializes in custom-designed, starved air systems that process solids, sludges
and hazardous liquids. The front-end gasifiers range from batch style tray furnaces to
ram-fed gasifiers to shredder-auger-fed rotary kiln gasifiers.
Successful permitting by our engineers has been accomplished in many states, including
Maryland, Michigan, Illinois, Colorado and Utah. Materials fired ranged from municipal
solid waste, hazardous PCBs, Saran fumes, explosive sludges, plastic scrap, trash,
medical waste and biomass. Several of the permits had heat recovery, primarily boilers,
however, in some cases the customers supplied the backend equipment and PIE was
responsible for material handling, gasification and oxidation front-end lines only.
For approximately 25 years, Robert G. Graham owned a shop and R&D lab in Sanford,
Michigan that employed engineers and skilled trades that designed, fabricated and lined
the custom equipment to meet customer specifications. In the future all of this
engineering and shop fabrication will be performed by Heat Transfer International (HTI).
David Prouty is President of HTI, (4720 44th Street SE, Kentwood, Michigan 49512,
telephone 616-551-5420). All of Mr. Graham’s intellectual property has been transferred
to HTI where he is under contract as the corporation's senior application engineer.
