Carbolite Gero

What Carbolite Gero does

Carbolite Gero Ltd. is a UK-based, privately held manufacturer of high-temperature furnaces and ovens covering a temperature range from 30°C to 3000°C, headquartered in Hope, Derbyshire. Its product portfolio is organized into four temperature tiers: ovens (up to 700°C, including laboratory, industrial, clean room, and atmosphere-controlled variants), chamber furnaces (up to 1800°C, including laboratory, industrial, ashing, and annealing), tube furnaces (up to 1800°C, in universal, split, rotary, and gradient configurations), and vacuum furnaces (up to 3000°C, including chamber, hood, bottom loader, laboratory, and tube variants). The company also supplies modified atmosphere equipment, custom-engineered furnaces, and its AriesPlus touch screen temperature controllers, alongside specialized systems for applications such as metal injection moulding, debinding, crystal growth, graphitization, pyrolysis, and thermocouple calibration.

The company has over 80 years of thermal engineering experience and an installed base of more than 100,000 products worldwide. It serves three primary customer segments: research laboratories (university, government, and private), pilot plants, and industrial manufacturing customers across automotive, aerospace, electronics, and materials processing. Revenue is generated primarily through one-time hardware sales of standard and custom-configured equipment, with prices set per specification; the company has recently introduced formalized Service Plans to add a recurring maintenance, warranty, and spare parts revenue stream. Distribution combines direct manufacturer sales with a network of 90+ worldwide distribution and service partners, supplemented by co-marketing under the Verder Scientific division of the Verder Group alongside sister brands Retsch, ELTRA, QATM, and Microtrac. The company employs 210+ people and maintains localized web presence in 14+ languages.
