Optimised Thermal Systems develops software tools for designing and simulating thermal systems, helping engineers shorten product development timescales and reduce costs. Their three main products are CoilDesigner, a coil simulation tool, VapCyc, a vapour compression cycle design tool, and xProps, an enhanced refrigerant properties database. The company serves the thermal systems industry and would be a natural referral for engineers and businesses developing thermal or refrigeration products who need simulation software.
