1.1 Overview

• SFB, a split pressure solar collector, making use of high vacuum absorption ratio and low emission ratio coating characteristics of solar vacuum tubes, converts absorbed solar radiant energy into heat energy by using a solar vacuum tube. Heat energy will be transferred into copper runner by heat pipe principle, finally transformed into heat energy that can be utilized by solar heating systems.

• This energy can be used for domestic and commercial hot water heating,centralized supply of hot water in hotels and hospitals,pool heating, space heating,solar desalination and solar thermal power generation.

• SFB consists of 7 commonly used models, 10 tubes, 12 tubes, 15 tubes, 16 tubes, 20 tubes, 24 tubes, 30 tubes.

1.3 Working Principle

The solar vacuum collector tube absorbs solar energy and transfers heat to the runner through the heat pipe. The circulating medium is heated when going through the runner. At the same time, the heat energy is transferred to the tank, pool, or heat exchanger by heat transfer medium.

2.1 Characteristics

• Pressure-type solar collector, working pressure 0.6Mpa, test pressure 0.9Mpa.

• The solar heat pipe adopts a phase change heat transfer design, having fast heat start-up. The heat pipe can reaches 222 ° C under sunshine when it is stand-by. which can provide high temperature hot water. Double-layer solar vacuum collector tube, AL/N/AL/SS/CU coating, absorption rate >92%, reflectivity<8%. The service life is 15 years.

• Automated equipment production copper runner with high precision.

• Perfectly integrated with the building and integrated into one. Suitable for installation on flat roofs, pitched roofs and on the ground

• Seamless connection with water tanks, boilers, heat pumps, gas water heaters, etc.
