In the city of İzmir, Solimpeks have built a drain meander system consist of 152 Wunder Drainback collectors, which produce hot water, for the Pasha Hotel, which holds a base in the outskirts of the town. The system can produce 55.000 litres of hot water per day. The project which was completed in June 2010 after commissioning began in February 2010, is first of the largest drain meander hot water installations in Turkey to date. In this project consist of 152 pieces Wunder Drain collectors; in this series sealed with EPDM, glazed with low iron tempered glass and used titanium coated copper inside. The double meander absorber optimizes heat transfer and allows drain back system use and 10 collectors to be connected in a single row. As for the other materials, seven pieces expansions tanks were installed and boilers where hot water can be stored up to 110 C degrees in the afternoon hours. Solimpeks in conjunction with themselves engineer team installed the system on a concrete roof without any damage of the roofing insulation. In this project amazing thing is will payback itself nearly in 29 months.
The features of Drain Back Collectors:
The meander collector that differs from other solar thermal collectors because inside the panel there are 19 copper pipes instead of nine that produces hot water on demand. The double meander absorber optimizes heat transfer and allows drain back system use and 10 collectors to be connected in a single row.
