Since the housing and peripheral equipment can often continue to be used, a retrofit is a cost-efficient way of drastically reducing the operating costs of an older system. Installing catalyst modules lowers the required operating temperature from approx. 800 \u00b0C to around 300 \u00b0C, which saves enormous amounts of heating energy. A retrofit is often carried out in response to stricter environmental regulations or rising energy prices and offers a fast payback with minimal construction
