Vacuum tube collector CRK-12 12 tubes incl. manifold WOLF # 2484854

The CRK collectors meet the requirements of the Blue Angel eco-label according to RAL UZ 73, high performance in a small space, high yields mainly during the transition period, particularly suitable for the combination of domestic hot water heating with heating support.
Powerful directly flowed-through collector based on the thermos flask principle, enabling lifelong vacuum and thus high insulation, hail-tested borosilicate safety glass according to DIN EN 12 975.
Absorber with highly selective coating on the outside of the inner glass tube in a high vacuum and thus protected from environmental influences, no degradation.
permanently high efficiency.
Optimal utilization of sunlight through efficient CRC mirror.
Flexible modular design to adapt to the space conditions on the roof, elegant appearance due to small pipe diameter, optimized pipe spacing and successful design.
Easy to install, compact and handy, completely pre-assembled, ready for connection, for mounting the collectors on tile roofs and free-standing installation.
