CG Thermal

What CG Thermal does

CG Thermal, LLC is a privately held US industrial process technology company founded in 2010 and headquartered in Twinsburg, Ohio. It specializes in heat and mass transfer equipment for harsh and corrosive process streams, designing and manufacturing proprietary graphite, silicon carbide ceramic, and composite heat exchangers, fluoropolymer components, and complete turnkey process systems. Its core technology platforms are organized around three proprietary material families: Impervite graphite (impervious graphite impregnated with proprietary resin), Umax alpha-sintered SiC ceramic, and the award-winning PPS-GR composite (68% graphite with polyphenylene sulfide binder) co-developed with Technoform. The product portfolio spans shell-and-tube, cubic block, and cylindrical (Multi-Blox) heat exchangers, high-temperature gas-to-gas recuperators (AirBTU VPRR), HTXP coils, fluoropolymer components, Pexgol piping, and full turnkey process systems for sulfuric acid, hydrochloric acid, nitric acid, sour gas stripping, and pyrolysis/specialty metal oxide applications.

Notable technical differentiators include the patented XD tubesheet design (US Patent awarded 2023) that enables larger-diameter corrosion-resistant heat exchangers at pressures up to 150 psig at 400°F, and a proprietary self-contained elastomeric tube-to-tubesheet sealing system that allows individual tubes to be field-repaired or replaced without full equipment change-out. PPS-GR received ASME Part UIG certification in January 2022 and won the 2023 VAALER Award for chemical industry innovation. CG Thermal's installed-base service life of 15–20+ years creates a long-tail aftermarket opportunity, which it captures through the Gulf Coast Graphite Services joint venture operating three US service locations (Port Allen LA, Mulberry FL, Twinsburg OH).

The company sells custom-engineered equipment and turnkey systems to enterprise customers through direct technical sales — no public pricing, project-by-project quoting. The go-to-market motion is enterprise field sales with engineering consultation, supported by major industry trade show presence (AIChE, SOCMA, CRU, ACHEMA, BCI, Chlorine Institute). End markets span chemical processing (sulfuric/HCl/HNO3/phosphoric acid handling), steel and metal processing (pickling, chem mill), battery manufacturing (lead-acid sulfuric acid dilution), fertilizer, mining and precious metals, environmental remediation (sour water stripping), plastics/VCM, and specialty chemicals/pharma. Geographic focus is North America (USA), though the company engages globally at industry events. The company is privately held with no disclosed external funding, revenue, or institutional ownership.
