OSO Delta PowerCyl F1 DF1

- Indirect unvented cylinder with high flow rate

The Delta PowerCyl F1 cylinders come standard with 1” hot and cold connections for high flow rates, and can operate at up to 6 bar pressure.

The Delta PowerCyl F1 l has large heating coils for fast heating times, and low heat loss due to the OSO ECO Foam insulation. Dedicated secondary return and a 25 year cylinder guarantee.

Delta PowerCyl F1 cylinders are supplied with an adjustable pressure reducing valve to be set between 1 and 5 bar. This enables the cylinder to supply showers requiring very high pressures and to locate the cylinder at low level and enable water to be been sent to higher floors and maintain good pressure at the outlet. Oversized expansion vessels are supplied to cope with the higher pressures involved.

1” hot and cold connections can deliver nearly double the flow rate of a standard cylin­der. Delta PowerCyl F1 is ideal where multiple showers/baths are fitted in the property. It is often used in light commercial situations such as hotels/guesthouses and can be banked together to increase capacity and flow rate. Where mains flow rate is insufficient, Delta PowerCyl F1 l is a perfect partner to the SuperStream system described opposite.

Delta PowerCyl F1 is designed to be supplied by mains water, but can equally work with boosted water from a break tank and pump set.

Heating coils in OSO cylinders are made of smooth coil that will not encourage lime-scale deposits and offer longer and more efficient life than finned or rippled coils. OSO coils have increased length compared to finned coils, carry more heating fluid and the­refore have a greater heat transfer capacity.
