Collectors

Without doubt the most technological advanced evacuated glass tube system available today.
Developed by Diamler-Benz Aerospace
Proven track record (12 years international)
We have tested the system in local conditions, and found it to achieve the highest temperatures out of a number of different vacuum systems..
Recorded temperatures of 80 degrees celsius on heavily overcast days.
Commercial and domestic applications.
Direct and indirect applications.

There are a wide variety of solar thermal collectors available and we supply units from a number of different manufacturers. There are two basic kinds of collectors:

1. Flatbed solar collectors
2. Vacuum tube collectors

Flatbed solar collectors are robust, cost effective, sleek in their low profile design and have proven themselves over a long period of time. They can be used in all situations, even in freezing conditions, as long as glycol is utilized.

Vacuum tube collectors are more efficient in cold climates due to the vacuum inside the tubes. Air in vacuum provides a high level of insulation and therefore these collectors are not prone to freezing. Some vacuum collectors can be rotated for the correct angle to the sun, while remaining flat on the roof. This helps in not having to build unattractive frames on roofs that do not have a north facing slope.
