PROBLEM

Scaling reduces the heat transfer efficiency and therefore increases the overall energy consumption of the heat exchanger.

Scaling enhances cost and energy consumption from exchange, cleaning, or replacement.

SOLUTION

An ultra-thin coating that creates a barrier against scale growth.

SiOx apply the coating for producers or end-users using a patented technology.

Domestic hot water production - a field study

SiOx is testing its coating in the field of domestic hot water production.

Plate heat exchangers are efficient, space saving, and cheap compared to hot-water tanks but scaling becomes a problem on the consumer side of the heat exchanger in areas with hard water. After successful laboratory tests SiOx is now testing the coating in heat exchangers connecting households to district heating.

The tests are carried out in collaboration with a large heat exchanger manufacturer and a major energy supplier. Our solution enhances the manufacturer’s product, lowers the loss of heat for the energy supplier, and saves the end-user money.
