Thermal Hazard Technology

THT is a world leader in the design, manufacture and supply of specialised calorimeters for use in the chemical and battery industries. Application areas include process development, optimisation and safety of chemical reactions, and determining performance and safety characteristics of batteries.

THT has over 25 years’ of calorimetry experience and offer a full range of adiabatic, reaction, and isothermal calorimeters. THTs products allow measurement of heats of reaction, derivation of kinetic parameters, assessment of maximum safe temperatures, and pressure generation.

THT’s flagship product, The Accelerating Rate Calorimeter (ARC), is the world's benchmark adiabatic calorimeter and provides full adiabatic runaway information for both temperature and pressure events. More recently the ARC has been developed to study safety and performance of Lithium Batteries. With the advent of large format cells for high power applications, THT introduced the EV+ calorimeter, the world’s leading calorimeter for battery applications.

Operating to ISO9001:2015 THT enjoys an exceptional reputation amongst leading scientific and industrial organisations.

Erwan Lhermitte

Managing Director

Erwan holds a BEng in Electronics and Computer Science and more recently obtained an MBA (Strategic Leadership) from Warwick Business School.
After an initial experience as an NPI engineer for X-ray flat panel detectors for digital radiography and fluoroscopy systems at Thales, he spent 9 years at Airbus where he held various engineering, project management and leadership positions pre-launch of the A380 and A350-XWB programs setting up key partnerships in France, Germany, North America, China, and North Africa.
He subsequently joined Spherea UK, an Aerospace & Defence electronics test equipment specialist, where he was appointed Managing Director in 2014, in charge of turning it around.
Erwan joined Thermal Hazard Technology as Managing Director in 2023.
