CWD of the latest generation

Our CWD of the latest generation measures the fuels for the glass industry independently of the gas type and will be presented at glasstec in Düsseldorf from 20 to 23.09.2022.
The product quality of the glass industry is particularly dependent on the fuel gas used and is therefore strongly affected by gas quality fluctuations.
We have been reliably and consistently determining the calorific value, Wobbe index and air demand for many years. For this reason, our calorimeter is already successfully in use. The special feature: the CWD measures all gas components (including the substitute gases) and is thus unique on the market.
Our sales partner STG Combustion Control GmbH & Co KG will present our CWD of the latest generation in hall 15 stand F14 and is looking forward to your visit!


UNION Instruments is the leading manufacturer of measuring instruments for the quality control of gas mixing plants. Due to the increasing demand, the company was able to achieve a significant increase in major orders for the instrumentation of liquid gas/air mixing plants. Customers include various globally positioned plant manufacturers, primarily from European industry, as well as regional and national energy suppliers.
Union Instruments GmbH has presented its new UV measuring technology to interested members of the specialist press. Its online measurement capability and the variety of different values which can be measured (such as H2S, THT, NH3 and SO2) – all of which can be determined simultaneously with very high accuracy, even in small concentrations – were especially interesting and positively received at the press conference.
