Product overview
Apricus AP range of evacuated tube solar collectors are suitable for both residential and commercial applications. The design of the AP solar collector is a culmination of nearly 10 years of feedback from installers and solar professional all over the world and aims to meet their requirements with the following
key features:
• Modular “plug ‘n’ play” design (Manifold, frame and tubes in separate packages)
• Lightweight manifold design
• Choice of Stainless Steel or Anodized Aluminium mounting frames
• Extremely reliable header design due to only 6 brazing joints
• Contoured header for turbulent flow even at low flow-rates
• All glass wool insulation for high temperature stability
• Patented heat transfer fin design for optimal heat transfer
• Long term stability under extreme conditions
• Extreme cold (freeze protected heat pipes)
• Coastal regions (salt spray)
• Harsh UV radiation (UV stabilized components)
• High Winds (up to category C cyclone)
• Snow loading

Solar Collector Operation
Step 1: The absorber coating on the inner glass tube absorbs sunlight and converts it into heat.
Step 2: Steam forms inside heat pipe which transfers heat rapidly up to the manifold.
Step 3: A pump circulates water or heat transfer fluid through the header pipe, carrying heat back to the
storage tank. Gradually throughout the day the tank is heated up.
