Process Tank & Storage Vessel Upgrades

Please contact Dove Thermal should you need to enhance the process performance of a tank or vessel – by improving heating, cooling or mixing arrangements for instance. We can undertake all the necessary calculations for determining performance of planned retrofits and their process effect, and modify the equipment on-or-off site as appropriate.

Process Vessels & Steam Calandria

We design and engineer shell-type research and custom autoclaves working under vacuum or positive pressure, heated either electrically, with steam or by HTF media. Specifically, we have capability and experience in designing and building custom autoclaves – along with the heat transfer and manufacturing processes undertaken in them. Process vessels may be jacketed or quilted, fitted with coils, steam calandria, or arranged for recirculation of their contents through primary heating or cooling equipment. Primary fluid systems for chemical reactors may operate isothermally (as with saturated steam or refrigerant) or be set up for sensible operation (with thermal fluid calandria, for example); whilst endo- or exothermic reactions may be tempered accurately to follow optimum process conditions with respect to time. We provide steam calandria for new or existing process vessels, tanks and equipment, fully supported by thermal design calculations and mechanical specifications.

Dove Thermal Engineering has more than thirty years experience in the process and mechanical design of heat and mass transfer equipment, including absorption columns, gas quenching vessels and cooling tower packings.
