Open-Loop or Closed-Loop Systems
Open-loop systems are both simple and economical. They are best suited for warm regions, because they operate with potable water only. Hot water from the collector mixes with the supply water in the storage tank, so a single freeze could destroy the system. Open-loop systems are not recommended in extreme hard-water areas, since scale buildup in the collectors is likely to hinder their operation.
Closed-loop systems prevent freezing and scale buildup. Heated anti-freeze solution from the collector flows into the tank’s heat-exchanger and then returns to the collector. An electric backup makes up the energy deficiency during periods of cloudy weather.
Mounted on apartment buildings, hotels, hospitals and industrial plants
Saga Energy’s central installations for home and commercial use, provide heated water in very large quantities by using an array of collectors. The number and size vary according to the water heating requirements. These installations are the perfect solution for apartment buildings, hotels, hospitals and industrial plants. They are generally backed up by conventional energy sources. Central installations can be operated with large storage tanks of over 1000 liters or with small individual storage tanks for each consumption unit Saga Energy`s manufacturer has vast experience in the design and implementation of large solar installations. Installations of this type require site specific designs. Not only are these applications resourceful they also contribute to a healthy environment by preventing air pollution and energy saving.
