2010 new split solar water heating system Solarkey

Closed Loop Solar Water Heating SystemThese systems pump heat-transfer fluids (usually a glycol-water antifreeze mixture) through the solar water heater. Heat exchangers transfer the heat from the fluid to the water that is stored in tanks. Double-walled heat exchangers or twin coil solar tanks prevent contamination of household water. Some standards require double walls when the heat-transfer fluid is anything other than household water. Closed-loop glycol systems are popular in areas subject to extended subzero temperatures because they offer good freeze protection. However, glycol antifreeze systems are more expensive to purchase and install and the glycol must be checked each year and changed every few years, depending on glycol quality and system temperatures.Advantage:1.Simple Installation,No Maintenance,Effective operation2. Easy Retrofitting To Existing systems3. Suitable for single and multiple solar heating Application systems,4. Preferred option for extremely cold areas and questionable water quality.I.ncoming potable water is routed to the solar storage tank6. Porcelain Enemal or SUS316 Stainless Stee Storage Tank With Electrical or gas Back Up7. Double-walled Copper Coil heat exchangers in storage tank prevent contamination of household water.Detail DescriptionInner tank: 1.material:food grade stainless steel SUS304 2.thickness: 1.2mm 1.5mm,seal the tank by argon-arc welding 3.work pressure 0.6Mpa,test pressure:0.9 Mpa 4.copper coil in tank: Red copper(Ø=12mm and thickness:1.0mm) 5.qty of copper coil: Single or double coils both availableOuter tank: 1.color steel with anti-corrosion layer & thickness: 0.4mm; (Option: stainless steel), cut and punching by numerical control machine insulation: 2. constant temperature workshop at 25 degree, avoid secondary foaming process. 3. density :30kg/m3,thickness over 50mm,keep the water hot for 72-80hoursElectricity heater:1.Input voltage: 200V 240V AC 50HZ 2.Power: 1500W or 3000W; 3.CE mark, 1 shape, can be 3/4inch or 1 inchcollector: 1.
