SUPERSTREAM – OSI
SuperStream provides boosted performance for poor mains supplies. Cold water storage using patented accumulator technology guarantees unrivalled pressure and flow rates for multi-outlet demand. Traditional unvented cylinders depend on incoming mains pressure and water volume to produce high flow rates. When mains performance is compromised, SuperStream uses stored cold water in a large virgin butyl diaphragm to deliver enhanced performance to hot and cold outlets.
SuperStream has a composite construction which is resilient and lightweight and is guaranteed for 5 years. The system is typically used in in large properties with multiple outlets or commercial situations with high water demand. If static mains pressure is poor, a Charger Pump can be used. contact OSO for details. SuperStream requires an additional purchase of an Upstream fittings kit with is supplied separately in 22mm or 28mm to connect to the cold mains and hot water cylinder – 200 and 250 litre models can be installed horizontally in optional cradle.
A SuperStream Charger (not included) is perfect for use in conjuction with the SuperStream accumulator. It pumps directly from the incoming main, eliminating the need for break tanks. the SuperStream system increases water pressure, and has a Green Energy saving bypass offering low energy consumption and quiet running at max. 38 dBA. The Charger offers flexibility of location, minimal maintenance and 2 year warranty on the Charger MJ1 pump.
The SuperStream Charger has a patent protected design.
WHY SUPERSTREAM?
• Boost performance for poor mains supply
• No moving parts – silent operation
• Perfect with Delta PowerCyl DCF Cylinder
• 5 year warranty on the tank
