  Liquid Phase Systems

Thermal Engineering spans a broad range of technologies. We originate equipment & procedures for new product development, process enhancement and in support of our own undertakings.


HTF and Hot Oil Liquid Phase Heating

Dove Thermal Engineering has designed and built unblanketed Thermia B liquid phase systems for hot oil heating at 290 deg.C using conventional hot oil boilers, Therminol 66 thermal fluid process heating installations working to 340 deg.C at atmospheric pressure, and re-engineered Dowtherm A installations running at 370 deg.C and 6.7 bar(g).

Solid State Thermal Appliances

Thermo-electric devices allow unique heating and cooling design opportunities for compact applications – particularly in aerospace and electronic environments. Consumer Products we have prototyped and developed include a table-top wine cooler, a chill box with freezer compartment, an immersion cooler, cooling jug and various machine coolers.

Quench Media & Cooling Processes

We apply the practical maths of heat transfer & fluid mechanics to all types of process cooling plant design projects. Accurate modelling enables "right first time" results in the design and construction of (for instance) batch and batch-continuous cooling plant and equipment, with accurate prediction of processing times.

Heating Media & Processes

Many of the reverse flame heaters now firing industry-standard continuous baking ovens are of our original design, while more recent work includes plant and equipment for hot box buffer storage, pressurized HTF systems and biomass autoclaving processes. We have designed and installed several boilerhouses and steam heating plants driving a variety of manufacturing operations, where isothermal operations offer significant advantages over sensible heating mechanisms.

Process Heat Transfer and Fluid Systems

Effective heating and cooling design starts with a clear understanding of the host operation and its behaviour. This page reviews how the fundamentals of heat-and-mass transfer underly all natural and man-made operations. Following from our design and construction of host systems, we develop working profiles to match duty conditions and originate heat exchange plant optimized for process improvement.
