Crystal Clear (TM) Selective Coating

Crystal Clear (TM) Solar-Selective coating is technically a Quartz Encapsulated Bimetallic Alloy. Thousands of nanocrystalline growth projections dramatically increase the surface area of the absorber plate for maximum solar radiation absorption and performance. Crystal Clear (TM) has been tested for over 1450 hours at 617F continuously with minimal visible or physical degradation of its thermal characteristics. Furthermore, Crystal Clear (TM) by itself enchances the thermal perfomance of the absorbers by an additional 3%. The finished coating hosts an Absorptivity of > 0.96 & Emissivity of < 0.08

THERMAFIN (TM) Absorbers

AET introduced THERMAFIN (TM) absorbers into the AE-Series collectors in 1996. Through extensive research and development, we have employed the best heat transfer method in the world today. THERMAFIN’s high-frequency, forge weld process molecularly bonds the fin to the tube providing long-lasting performance and durability while allowing the highest heat conduction. The high-frequency welded joints will not weaken, expand, or pull apart and are backed by written 30 year guarantee. 

Baked Polyester C-Channel Construction

Our AE-Series Collector frames are fabricated in our state-of-the-art manufacturing plant located in Jacksonville, Florida. Crafted using extruded baked polyester (MB-40) electrostatic bronze painted aluminum and securely fastened with aircraft grade pin grip rivets, AE-Series Collectors are built to withstand the most demanding environments.
