Our water treatment unit is also available as a stand-alone module for condensate treatment, filtering and automatic sludge removal. The treated water can be drained into a sewage network without additional cleaning.
CSX B is the basic model of the Caligo scrubber family. CSX B includes particle filtration and washing of flue gasses, one heat recovery zone, a water treatment unit and sludge treatment system.
CSX HPC is recommended when a basic scrubber is sufficient at the time of investment, but the district heating return temperature may rise in the future. In CSX HPC space has been reserved for a second heat recovery zone and connections to the heat pump (it does not include a heat pump). The design reservations in the amount and flow of the condensate are also taken into account.
CSX HP is equipped with a heat pump and the high heat recovery performance of the model is based on our patented heat pump connection. The heat pump connection insures maximum heat recovery even when the district heating return temperature is high. In this situation traditional flue gas scrubbers start to fail. Our heat recovering technology can reduce fuel costs by up to 30-35%.
Caligo scrubber technology is based on modularity. All of our scrubbers have two modules: a scrubber module and a water treatment module. There is a washing zone inside the scrubber module and, depending on the model, one or two heat recovery zones through which flue gases are led.
The condensate is led to the upper part of the water treatment module, which works as a clarifier that separates most of the solid content from the water. From there the water is gravitationally filtered in a sand filter situated under the clarifier. The filter sand is backwashed automatically with the purified condensate and the dirty washing water is led back to the clarifier.
Our product range includes four different scrubber and water treatment products. The letter X in the product code indicates the size of the boiler in megawatts.
