COPPER CYLINDERS CLOSED CIRCUIT


The advanced materials used and the attention to detail ensure ultimate efficiency and long-lasting lifespan for your solar heater. All products are manufactured in accordance with European standards, while the accurate tests and systematic inspections provide high reliability and security, both to the user and the environment.

Our full production line, consisting of closed circuit solar heaters with a capacity ranging from 160ltr to 400ltr, is especially designed to meet every need.

 

Technical Specifications – Closed Circuit Copper Cylinder:

  • Outer Casing: made of INOX or pre-painted white or grey metal sheets, depending on the customers needs.
  • Cylinder/Boiler: made of copper. Content: 99.90%. Cup-shaped copper (x2), according to standard EN1652, thus doubling its lifespan.
  • Second copper shell: made of copper. Content: 99.90%
  • Cold water entry/exit: copper tubes Ǿ 26mm with thread
  • Cold water exit to collector and hot water entry from collector: copper tubes Ǿ 26mm with thread
  • Pressure test: pressure tests are carried out on every cylinder manufactured up to 10 Bars.
  • Heating element: 3kw with a second safety thermostat (over low), ensuring hot water even when the weather is cloudy.
  • Heat exchanger (coil): Ǿ 18mm, enabling to connect it to the central heating (made to order)
  • Strong insulation: ecological polyurethane of high density 50mm with a thickness of 50kg/m3. Keeps hot water for a long period of time, even during the coldest days of winter.
  • Side covers: Posted without screw connections. Fully sealed.
