Independent: Decentralised supply reduces costs for electricity

The curtain manufacturer UNLAND International GmbH made itself more independent of central utility companies, switched to natural gas and, as a result, significantly reduced the electricity costs. bwe built the decentralised supply for them and supplemented this with an additional combined heat and power plant (CHP). 

Thus the company can economically warm thermal oil and, at the same time, the washing water for the industrial textile washing.

Thermal oil boiler 

For this purpose bwe installed a natural gas CHP with 365 kWth and 240 kWel in addition to the already existing CHP with a capacity of 290 kW and two large thermal oil boilers with a capacity of 2500 kW. 

Now two CHPs and a photovoltaic system generate electricity for internal use in the UNLAND facility. The thermal capacity of the CHP makes it possible to heat eight cubic metres of high temperature thermal oil from 220 to 240 degrees and, at the same time, to generate low temperature. 

Energy costs reduced

A sophisticated controller connects the various elements.

The changeover to gas for thermal and electrical purposes and the intelligent use of the CHP technology had an immediate affect on the curtain manufacturer’s internal energy costs.
