Solar Central Hot Water System SOL-T Series

The solar central hot water system uses solar collectors to convert solar radiation into thermal energy, combined with auxiliary heat sources to provide domestic hot water for hotels, schools, hospitals and other facilities. The annual sunshine hours in Harbin region are approximately 2500 hours, and the annual solar contribution rate can reach 50%-65%.

System Components

  • Solar collectors: All-glass evacuated tubes or flat plate type, collector area 100-2000㎡
  • Hot water storage tank: 304 stainless steel inner tank + polyurethane insulation, capacity 5-50 tons
  • Auxiliary heat source: Air source heat pump / gas boiler / electric boiler for automatic heating supplement
  • Control system: PLC + touch screen, differential temperature circulation + timed water supply + anti-freeze circulation + overheat protection

Anti-Freeze Design (Critical for Northeast China)

  • Dual-loop indirect system, collector circulation uses antifreeze (does not freeze at -35℃)
  • Outdoor pipelines with electric heat tracing + rubber-plastic insulation, automatically activates heat tracing when below 2℃
  • Automatically drains outdoor pipelines during extreme weather to prevent freezing cracks

Reference case: A five-star hotel in Harbin equipped with SOL-T system, collector area 800㎡, daily output of 40 tons of hot water at 55℃, saving approximately 45,000 Nm³ of natural gas annually.
