ABSORBER MADE OF ALUMINUM AND COPPER
Using an aluminum plate allows production of a lighter collector with lower production costs. Laser welding provides maximum durability and mechanical strength through joining aluminum plate and copper piping and excellent transmittion of heat to heating medium.
SELECTIVE PVD COATING (95%/5%)
Selective PVD coating is characterized by highest work efficiency, due to absorbing of 95% of solar radiation and heat emission of no more than 5%.
TEMPERED GLASS (U1 CLASS)
Tempered glass is characterized by high transmittance of solar radiation – highest U1 class, almost 92% of solar radiation passes through the glass to the inside of the collector and therefore more accesses the absorber.
EFFECTIVE THERMAL INSULATION
The thermal mineral wool insulation at the bottom of the casing reduces heat loss and allows the collectors to operate efficiently in various conditions.
OPTIMAL FLOW
The harp system with 4 connections lowers the flow resistance, which reduces energy consumption, protects the medium against overheating and allows you to connect up to 8 collectors in a row.
10 YEAR WARRANTY
Since the 1990s, Hewalex has been granting its` Customers the longest warranties on the market for solar thermal collectors. The standard warranty on F TLP AC collector is 10 years.
