thermal systems engineering.

A high-tech development project starts with a fundamental understanding of the customer’s problem, the real question behind his initial request. Starting from that, we define the critical end-user requirements. Even when things become really complex, we take up the challenge to create a system architecture that provides the best multidisciplinary solution, in terms of functionality, quality, time and cost. We follow a structured systems engineering approach to translate the architecture into a validated design. Drawing on our broad knowledge, we design innovative concepts, explore creative solutions, and perform feasibility studies.


  • (thermal) architecture and design
  • system integration, testing and verification
  • prototyping, modelling & simulation, experiments
  • V-model methodology and agile way of working

from 2000°C down to -273°C.

Thermal Systems Engineering combines thermodynamics, fluid flow, and (sometimes) vacuum technology. Demcon kryoz specializes in this sub-discipline of engineering that deals with thermal energy and its transfer between different media, thermal storage, and conversion into other types of energy or work. This spans the entire temperature regime, starting from extremely high temperatures (2,000°C) down to cryogenics (-273°C).

Our thermal engineers are armed with extensive expertise in all aspects of heat transfer, system design, modelling, realization and testing, with a fully hands-on mentality.

"from concept to product"

“Whatever you want your high-tech machine or system to accomplish, very often at its basis are the fundamental physical interactions of thermal dynamics. From concept to product, as curious thermal systems engineers we combine a thorough understanding of these effects with our expertise in multi-discipline concurrent engineering and design, to achieve the optimal solution: your thermal issue – solved!”
