![]() ![]() Evacuated Tubes are are extremely efficient by virtue of the Tubes themselves. While both types of collectors capture the suns energy and convert it to hot water each have there own advantages.Įvacuated Tube Collectors are best used in northern climates where freezing can occur and can be utilized in areas where temperatures drop down to -60☏. Fittings: the size and type of fittings used to connect the collector to the piping system, in this case, 1” male NPT.Glass to Metal Seal Type: the type of seal used to connect the glass and metal components of the tube, in this case, hermetic.Manifold Socket: the type of socket used to connect the manifold to the tubes, in this case, soldered dry socket.Heat Transfer Method: the method used to transfer heat from the evacuated tubes to the heat transfer fluid, in this case, heat pipe.Heat Transfer Fluid: the type of fluid used to transfer heat from the collector to the storage tank, in this case, water/glycol.Stagnation Temperature: the maximum temperature that the collector can reach when there is no fluid flowing through it, measured in Fahrenheit and Celsius.Maximum Pressure: the maximum pressure that the collector can withstand, measured in psi and bar.Operating Pressure: the recommended range of operating pressure for the collector, measured in pounds per square inch (psi) and bar.Max of Tubes in series: the maximum number of tubes that can be connected in series.Orientation: the orientation of the collector, in this case, portrait.Tilt Angles: the range of angles that the collector can be tilted for optimal performance, measured in degrees.Flow Rate per Tube: the flow rate of the heat transfer fluid per tube, measured in gallons per minute (gpm) and liters per minute (lpm).Pressure Thrust: the maximum pressure that can be exerted on the tube, measured in Megapascal (MPa). Heat Loss: the amount of heat lost from the tube per unit of surface area and temperature difference, measured in Watts per square meter per degree Celsius (W/m2.oC).Vacuum: the level of vacuum inside the evacuated tube, measured in Pascal (Pa).Coat Emissivity: the ability of the coating to emit thermal radiation.Coating Absorbance: the percentage of solar energy absorbed by the tube coating.Thermal Expansion: the amount of expansion that occurs due to changes in temperature, measured in inches and millimeters.Tube Coating: the type of coating applied to the evacuated tube for maximum performance and efficiency, in this case, Al-N/Al.Tube Material: the type of material used to make the evacuated tube, in this case, borosilicate glass.Inner Tube Diameter: the inner diameter of each evacuated tube, in inches and millimeters.Outer Tube Diameter: the outer diameter of each evacuated tube, in inches and millimeters.Tube Length: the length of each evacuated tube, in inches and meters.Pool and spa heating: Large and small pools.Radiant floor heating: Systems of any size.Domestic hot water: Normal hot water for a house.SRCC Clear C Rating ( kBTU/panel/day ) 41.4.Inner Tube Diamete r (in)/(mm) 1.60 /43.Outer Tube Diameter (in)/(mm) 2.28 / 58.Hardware required for collector assembly.30 Revolutionary SunMaxx Evacuated Tubes.Assembly Time: A collector can be assembled in 1.5 hours.Packaging: Ships via freight on a pallet or is available for local pickup (1 pallet is available for residential or commercial delivery.). ![]()
