Hot gas test beds

Testing under heat and pressure.

Continuous temperature and flow control, combustion chamber without ceramics and accurate metering even at high pressure.

Using a combustion chamber we developed ourselves featuring precision selection of the gas and air mix and a sophisticated valve system for controlling flow and pressure means our hot gas test beds can deliver a continuously adjustable map showing temperature, pressure and flow rate across a wide load range. As a result, there are no problematic changes in temperature and pressure when switching conventional cascaded combustion systems. The hot gas systems we at KS Engineers develop from scratch are now the benchmark on the market and a typical example of the company’s capacity for innovation and the flexibility we demonstrate in responding to your specific needs.
