General product description TWL Combi- hygienic storage 90°

With a 90° combi hygiene storage unit you not only conserve resources, but also your wallet. If the heating system and the 90° combination hygiene storage tank are optimally matched to each other, the cash is worth it. Those who use modern storage technology efficiently can effectively save a lot of energy with the right devices.

Space-saving and efficient storage of drinking and heating water

When heating and generating hot water, you can not only save energy but also money with a 90° combination hygienic storage tank: TWL hygienic storage tanks are used in heating systems with integrated DHW heating in the tank. The drinking water heat exchanger is made of high-quality stainless steel - and thanks to its large surface, the stainless steel exchanger guarantees excellent hot water performance. Due to electrochemical corrosion, the heat exchanger is mounted on a flange plate with insulating separation in the tank.

Drinking water quality is a top priority with the TWL 90° combination hygienic storage tank

With the TWL Combi Hygiene Storage 90° you always get real fresh water, which is always heated precisely at the moment you actually need it. The formation of pathogens such as legionella is avoided by the low use of water supply. In contrast to classic drinking water tanks, no anode is required. For this reason, you do not have to bear the usual maintenance costs when purchasing a 90° combination hygienic storage tank.

Technical perfection guarantees optimum heating of drinking water

Thanks to a special design, there is no contact between the stainless steel exchanger and the steel buffer tank. On the top side of the tank there is a flange ring in which the stainless steel heat exchanger for drinking water with flange plate is mounted. Special insulation separations also ensure that the stainless steel of the heat exchanger is not connected to the steel of the buffer tank. This results in the following result: In contrast to other stainless steel exchangers there is no contact corrosion, often the stainless steel exchanger is mounted directly on the steel, which can lead to stress corrosion. The TWL 90° combination hygienic storage tanks are available with a capacity of 500 to 1000 litres. And the perfect insulation ensures excellent insulation values.
