PRE-heat, Inc. provides efficient, state-of-the-art solutions for customers in various industries. Recently, we were contracted by the oil refinery industry for a custom heat exchange that was attached to a thermal fume incinerator manufacturing project. What we are most proud of is the selection of our company in a competitive marketplace to directly replace a pre-existing heat exchanger unit. This opportunity allowed us to prove our capabilities to provide more efficiency, while simultaneously showcasing our proprietary free floating air seal expansion system. This system is the best in the industry and lasts longer than other units, while still maintaining the integrity of the unit and the seal between air streams.

Utilizing our in-shop, top-of-the-line equipment, we manufactured the entire thermal fume incinerator. The system consisted of CS hot air outlet plenum with internal insulation, stainless steel stacks and service platform, and stainless steel inlet ductwork. Some of the features of our system included 4 shell pass, vertical shell and tube heat, exchangers (each handling 15,000 SCFM) installed in parallel, and hot heat exchangers with 309l S.S. tubes and tube sheets. In addition, both exchangers have intrical cold side face and bypass dampers, and re-cover heat from 30,000 SCFM of 1,500°F.

Our ideas and equipment are only as good as our final product. To that end, we implement in-process testing of our products to ensure our client's standards are met. For this project, the shell was all die penetrated tested, and was built while using our standard Quality Control Sheets/system. When all units were completed within 12 weeks of receiving the approved drawings, we were proud of our work and our customer was satisfied with our quality and timeframe.
