DXT was founded on thermal energy systems. We design heat exchangers and boilers, size the heating surfaces that make a plant efficient, and design the control systems that run them — the engineering behind the strength calculations.
Our thermal work spans single- and multistage absorption and ejector cooling, heat-driven cooling from low-temperature sources, and boiler and heat-exchanger design. We model the process and size the equipment so the thermodynamics and the mechanical design agree.
DXT has worked on heat-driven cooling that exploits low-temperature heat sources below 80 °C — single- and multistage absorption plants with LiBr/H₂O and NH₃/H₂O, and single- and two-stage ejector cooling based on water.
Denmark’s relatively low outdoor temperatures make it possible to use heat sources as low as 55 °C. Below the freezing point, water/ammonia plants are generally preferred; for gaseous heat sources with high water content, ejector plants have process advantages.
