What Ets Schaefer does

ETS Schaefer, LLC is a privately held, Ohio-based designer and fabricator of ceramic fiber refractory products and systems, serving industrial manufacturers with high-temperature heat-containment requirements. Founded approximately in 1954 and reincorporated as an LLC in 2010, the company operates a single headquarters in Macedonia, Ohio and self-describes as a global leader serving customers worldwide. Its offerings combine proprietary monolithic lining systems (Monster Module™, Perm+A+Lining®, Monster Lock™), commodity-grade ceramic fiber bulk and blanket products under the K-Lite™ brand (RT, HP, and HTZ temperature grades), fabricated items such as ladle covers, tundish preheater covers, furnace doors, and ductwork, and a dedicated endothermic fire protection product (EndoFlex Mat®) for electrical pathway integrity. The portfolio is sold direct to enterprise industrial buyers — customers documented in the source material include Titanium Metals Corp (Timet) in aerospace/titanium forging and Mittal Steel in integrated steelmaking — with engineered project work backed by structural steel fabrication capability and on-site installation crews.

The underlying technology centers on one-piece continuous ceramic fiber construction that eliminates through-joints (and the associated hot spots), combined with proprietary attachment systems that anchor linings to furnace shells. Customers report longevity benefits consistent with this architecture: Timet recorded no downtime due to lining repairs since a 1996 Monster Module™ installation and approximately $500 per operating week in fuel savings, and subsequently standardized the system across all eight of its ingot forge furnaces. ETS Schaefer supports customers through furnace surveys, fuel savings analysis, engineering consultation, demolition, and field repair services, with a dedicated RENEW™ program for replacement and refurbishment.

Commercially, the company operates a sales-led, direct-to-customer motion via phone and email, with a small digital presence limited to a brochure-style website and downloadable technical PDFs. Revenue streams span one-time product sales of both commodity and fabricated items together with installation and field service engagements; pricing is not publicly disclosed. The company does not list investors, parent companies, or acquisition history, indicating independent private ownership, and management team information is not disclosed in the available sources.
