Racold Advantage

Evacuated tube collector

• Evacuated tube – optimised length:

– 1800 mm long evacuated tube for high energy absorption.

– Higher efficiency as per international standards.

Racold Advantage

Evacuated tube collector

• Sun-Max reflector:

– V-shaped reflectors for superior absorption.

– Full length reflector fins – no gaps - for Max reflection.

– Special grade material for reflectivity of upto 90% - optimum reflection back to the tubes.
