DeSeM Engineering
At DeSeM we have been carrying out consulting and engineering design work for many years starting back in 1975.
Our design work includes pressure vessels, re-boilers and heat exchangers, chimneys, chemical plant, handling systems, municipal and industrial effluent treatment plant, oil containment and storage silos as well as varied structural designs for external lifts and buildings. 
We offer a range of services for bespoke equipment including the design, the detail design issue for manufacture (sometimes by our Clients) and calculations for insurance or others verification. 
We have our own thermal design engineer Bill Watson who ranks within the countries finest on heat transfer.
Pictures shown below are of some of our designs in tangible form and mostly manufactured by us. They are self explanatory and offer a taste of our skills
