Solar Drain Back Cylinder

Solar Drain Back

McDonald Engineers UK has manufactured a bespoke 1000 x 200mm solar drain back cylinder for a renewable energy project in the Channel Islands.

The solar drain back cylinder is being used to allow the fluid in solar panels to empty when the circulation pump is not running, which eliminates the risk of freeze damage to the panels.

The cylinder was manufactured from copper and to McDonald Engineers UK’s superior quality standards and was finished in a white case to improve the aesthetics.

Technical Sales Manager, David Stewart, explained, “We have manufactured a large number of solar drain back cylinders for specialist installers of solar energy, who like the fact we can manufacture them to their exact specifications to suit the project.”

He continued, “As a result, we have manufactured a range of sizes and specifications, including a rectangular tank which was designed to fit into a wall mounted cabinet which also accommodated the pump systems.”
