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.
All Chromagen systems are supplied with a connecting kit that includes all the required accessories for installation.
Chromagen supplies a variety of stands and racks for flat or inclined roof installations. Chromagen stands are made of galvanized painted steel to ensure high durability in harsh conditions
