UNISA has purchased all its Thermodynamics equipment from ESSOM, and herewith we would like to express our satisfaction with the products. The equipment is effective; experiments are repeatable with a high degree of accuracy and a great deal more value for money. We have commissioned some of the equipment and are now in the process on commissioning the Steam Power Plant. The Boiler is working well. I am pleased with the progress made so far. I hope we will have a good working relationship, throughout the considerable long life-span of this equipment.
