Solar flat-plate collectors SUNSYSTEM PK Select CL

от 558,00 лв.

Due to their excellent absorptance rate of 95% flat-plate collectors SUNSYSTEM PK Select CL are the ultimate choice for domestic hot water supply and central heating support throughout the year.
The collector absorbs solar heat and emits it to the heat carrier circulating in the pipe harp.

Features

Absorber harp of copper fins

Inclined roof / Flat roof

Selective coating

Thermostatic regulator

Protective solar glass

Product features:

State-of-the-art selective coating boosts efficiency and protects the absorber from wear.
Weatherproof aluminum frame; installable in multiple positions.
Rock-wool insulation keeps heat from escaping the collector case.
Absorber harp of copper fins welded by ultrasonic technology. Ultrasonic welding provides for even and solid seam between the piping and the fins which withstands mechanical and thermal deformation.

Pipe harp with low flow resistance. 100% tested for liquid tightness.
Protective solar glass: prismatic surface patterned, low ferrous content (FeO ≤0.02 %), heat-tempered, weatherproof – withstands severe wind, snow and hail.
UV-proof silicone seal.
Certificate: EN 12975:2006-06; CEN – Keymark 011 -7S381 F.
