JJ ETC Series Split Solar Water Heater Closed Circuit, Can Withstand Temperature As Low As -15℃
The best design and configuration for environments prone to frost, the JJ ECT Evacuated Solar Collector and Hot Water Tank Heat Exchange technology to maximise solar gain and protect against all weather extremes. The JJ ECT Series replaces water in the solar collectors with a special heat exchange fluid with anti-freeze properties. The design is both safe and efficient, as fluid drains out of the solar collectors to prevent freezing and heat loss in cold conditions, and overheating in hot climates.
JJ ETC Series Family has 150L, 200L, 300L, 400L, 500L.
Hurricane Resistant Mounting Frame is available.
Product Features
Titanium Blue Solar Water Tank
JJ solar tank enamel coating is made from titanium blue enamel powder, and meet drinking water standard. Enamel Solubility reach Y class, and resist against 85℃ hot water. Longer Tank Life.
Unique Appearance and Excellent Performance Solar Collector
High efficiency evacuated tubes to absorb the maximum available solar energy, withstand temperature as low as -12℃.
Over High Temperature Operation
When the water in the solar storage tank has reached 75°C , the circulator will be deactivated.
Strong Anode Rod
JJ solar tank is equipped with stronge anode rod can perfectly protect the water heater tank against the corrosion, and ensure the even longer life of water heater.
How Split Solar Water Heater Work
JJ ETC closed circuit solar water heater has its vitreous enamel lined solar storage tank installed at ground or floor level, remotely from the Evacuated solar collectors. This water heater is an indirect solar hot water system with a heat exchanger in the solar storage tank.
The heat exchanger is filled with closed circuit fluid and is connected to the Evacuated solar collectors forming a closed circuit. The closed circuit fluid is propylene glycol concentrate mixed with water. The closed circuit concentrate is used to lower the freezing temperature of the closed circuit fluid and provides protection against freezing.
As the sun heats the sEvacuated solar collectors, the increase in temperature activates the pump. The pump switches on whenever the Evacuated solar collectors are hotter than the water in the tank. The pump moves the closed circuit fluid from the solar storage tank heat exchanger through an insulated copper pipe to the solar collectors to be heated by the sun’s energy and then back to the heat exchanger. Heat transfers from the closed circuit fluid in the heat exchanger to the water stored in the solar storage tank.
