Tube collector
CRK-12

The most efficient solution if you want to make use of the full strength of the sun even in spring and autumn.

The WOLF CRK 12 vacuum tube collector achieves excellent yields even with low insolation or less than optimal orientation. This assures you of solar-generated heat and hot water even in spring and autumn, and means you also save on costs for oil or gas during these seasons. The CRK can be designed on a modular basis, i.e. you can connect several collectors in series to suit the space available on your roof. Even if conditions on your roof are not ideal, you can still enjoy solar central heating and hot water with the CRK 12.

Short Info
Technische Daten

TUBE COLLECTOR CRK12

This high tech solution for maximum energy yield on the smallest of footprints offers the highest level of DHW convenience.

The WOLF vacuum tube collector achieves excellent yields even in spring and autumn, and is therefore ideal as a solar thermal system for DHW heating and central heating backup.

The clever design creates high output from a very small collector area
High yields enable DHW and central heating backup even in spring and autumn
The vacuum keeps the heat generated by the solar rays inside the tube and almost no energy is lost to the outdoors
The absorber is on the outside of the inner glass tube inside a high vacuum so it is protected from environmental influences. You benefit from the fact that there is almost no output loss due to ageing and you can enjoy a solar thermal system with permanently high levels of efficiency
Thanks to the modular design of the collectors, the solar thermal system can be easily adapted to the space available on the roof

IN SPRING, SUMMER, AUTUMN OR WINTER – GENERATE HEAT FOR YOUR HOME FROM SOLAR ENERGY

Small, sophisticated and powerful: with the CRK 12 from WOLF, you have a "high tech solar generator" on your roof that always delivers peak performance.

The WOLF CRK 12 tube collector provides central heating backup all year round, assuring you of a warm and cosy home and plenty of hot water. It harvests 15 % more solar energy than a flat-plate collector of comparable size. This means you can make optimum use of the sun's rays, especially in spring and autumn. What's more, the CRK 12 takes up only a little of your roof space and delivers its output even if the angle of inclination is less than ideal. Treat yourself and your family to the highest levels of energy efficiency, reliability and durability, as well as the satisfying sense that you are making the most of solar energy.
