What Ceramic Furnace Construction does

Ceramic Furnace Construction (Keramischer OFENBAU GmbH) is a German industrial kiln manufacturer founded in 1996 and headquartered in Hildesheim, Lower Saxony. The company designs, engineers, manufactures, installs, and maintains industrial furnace and kiln systems for the global ceramics industry, operating at temperatures up to 1,800°C. Its portfolio comprises three core kiln platforms — roller kilns (Type eRO), tunnel kilns, and hearth car kilns — complemented by proprietary add-on technologies such as the EnerViT energy-efficient firing system (up to 50% energy savings, H2-ready variant), the eHWO fully electric shuttle kiln, the eTO fully electric tunnel kiln, and the IsoViT system for ceramic insulator manufacturing, along with process visualization (ProVis) and combustion control (LAMBDA) software. The company delivers complete lifecycle support including modernization, retrofitting, spare parts, and 24-hour service.

The firm serves enterprise customers across tableware and porcelain, sanitary ceramics, building ceramics, technical ceramics, battery cathode materials (for Li-ion batteries), and high-temperature fuel cell components (SOFCs/SOECs). Named customers include LAUFEN Bathrooms, Roca Group, Duravit, Villeroy & Boch, Seltmann, Sanindusa, Keramag, Steinzeug, Kyocera, BHS Tabletop, and various fuel cell manufacturers. Revenue is generated through one-time new kiln sales, modernization and retrofitting projects (with short payback periods), spare parts (including for competitor equipment), and recurring service contracts. The business operates a direct enterprise sales model with field sales engineers, international sales representatives, and a wholly-owned Indian subsidiary (Keramischer OFENBAU India / KOI) in Noida, serving customers in over 45 countries with a team of approximately 50 employees.

The company positions itself as a technology leader in kiln energy efficiency and decarbonization, claiming the world's first fully electric tunnel kiln for sanitary ceramics (built for LAUFEN's net-zero factory) and H2-ready combustion capability. It maintains research partnerships with German universities and federal R&D programs (AIF, ZIM), and pursues international market development through active trade show participation at ceramitec, ASEAN Ceramics, Indian Ceramics Asia, ISH Frankfurt, and EFCF Fuel Cell Forum. The company is privately held by its three managing directors (Thomas Alten, David McGuinness, and Dr.-Ing. Claus Thomy), has received the 2023 Lower Saxony Foreign Trade Award and the 2025 CrefoZert for outstanding creditworthiness, and reports strong order intake as of 2025.
