Non-Pressure Solar Collector
Evacuated Tube
Solar Collector
SolarMaster SNC series of evacuated tube solar collectors
are suitable for both residential and commercial applications.
The design of the SNC solar collector is a culmination of nearly
15 years of feedback from installers and solar professionals all
over the world and aims to meet their requirements with the
following key features:
● Easy and Safety Packing design 
● Stainless Steel 304-2B or 316L for inner manifold
● Zinc-Coated Galvanized Steel frames
● Extremely reliable inner manifold design, less soldering points
● All glass tubes have three absorb coatings with high heat efficiency
● Extreme High density Polyurethane Foam from Europe for            insulation layer
● UV stabilized components
● High wind load strength and High snow load strength
● Easy plug-in installation
SNC collectors are available in 15 to 50 tube sizes and have a number of options depending on the local market requirements.

How It Works
The SNC solar collector is comprised of three main parts:
Evacuated Tube
Absorbs solar energy and converts it to usable heat.  Vacuum between the two glass layers insulates against heat loss.
Insulated box containing the stainless steel inner shell and with the extreme high density Polyurethane foam for keeping the hot water.  The header with well design for glass tubes plug into.
Mounting Frame
Strong and easy to install with various options to match different mounting methods.
Step 1: The absorber coating on the inner glass tube absorbs sunlight and converts it into heat. 
Step 2: The cold water inside the inner tubes be heated and become hot water even to steam. The new cold water will go down and hot water will go up automatically.
Step 3: A pump circulates water or heat transfer fluid through the manifold, carrying heat back to the storage tank.  Gradually throughout the day the tank is heated up.
