DELTA POWERCYL — DCF can deliver nearly double the flow rates (up to 5bar) of a standard cylinder with its 1” connections. DCF is an ideal choice for small hotels/ guesthouses with multiple showers/baths. a 1- 6 bar adjustable PRV valve and oversized expansion vessel are supplied as standard.

DCF is a perfect partner to the SUPERSTREAM system where mains flow rates are insufficient. DELTA series is the most efficient hot water cylinder available uitilising unique Vacuum Panel Insulation.

DELTA series is a part of the award-winning Delta Coil range, and through the incorporation of Vacuum Insulation Panels it can save enough energy to pay for the entire cylinder over its lifetime.

Delta powercyl can be controlled either via using a thermistor probe or its own digital thermostat with digital display of water temperature.
