Sonnenkraft VK25

 
Sonnenkraft-VK25

Features of evacuated tube collector VK25

Higher output due to vacuum insulation
High temperatures – even in poor weather conditions
High output due to exploitation of diffuse and oblique radiation via CPC reflector and circular evacuated tube absorber
Simple maintenance – tubes can be changed without having to drain solar circuit
Simple assembly process – low assembly costs
High output even at lower outside temperatures

Evacuated tube collectors ensure high output at low outdoor temperatures, particularly when used with heating systems. Collectors are delivered as prefabricated modules for roof mounting. Collectors consist of a base frame, manifold housing, CPC reflector, heat exchangers and evacuated pipes including absorber. 

Works Well Even In Low Temperatures

The vacuum insulation ensures high output and high temperatures – even in poor weather conditions with low outside temperature. 

Simple Maintenance
It is possible to change the tubes of the VK25 without having to empty the solar loops. 

High Efficiency
The VK25 has a high output due to exploitation of diffuse and oblique radiation via CPC reflector and circular evacuated tube absorber
