COMPANY HUSTERT GALVANIK IN RAHDEN, GERMANY

MIDSIZE ENTERPRISE INVESTS IN SOLAR PROCESS HEAT

• Location: Rahden, North-Rhine Westphalia, Germany
• Solar heat for electroplating processes
• Collector area: 221 m²
• Came into operation: Summer 2011

The main bussiness of midsize family-run company Hustert Galvanic is electroplating parts for the automotive industry. The dipping basins are heated by an oil-fired boiler plant. Since July 2011 this is partly done by a large solar system of Ritter XL Solar.

The target temperature for the galvanic basins is 80 °C. 45 vacuum tube collectors, in total 221 m² gross surface, feed directly into the hydraulic separator of the existing boiler plant with up to 90 °C. Since the solar output is mostly below the process needs, storage tanks are not necessary. Summer peaks are buffered in the dipping basins.

The expected annual yield of the solar system is 95.000 kWh, saving 35 tons CO2. Taking the average efficiency of the boiler system into account, the oil consumption will be reduced by 12,500 liter of oil every year.

The installation of the complete plant took place via the local resident company Schapka (building services).
