OSO DELTA POWERCYL
DCF

Ultimate energy efficiency and maximum flow rate - ErP A

DELTA series is the most efficient hot water cylinder available, uitilising unique Vacuum Panel Insulation and is the only full range of ErP* A-rated cylinders available from 250 - 380 L. DELTA boasts 30 - 50% higher efficiency than rivals, translating into direct SAP gains. DELTA series can save enough energy to pay for the entire cylinder over its lifetime. Delta has holiday and anti-legionalla finctionality. * Energy-related Products Directive – 2009 / 125 / EC. 

DELTA POWERCYL— DFC can deliver nearly double the flow rates (up to 5 bar) of a standard cylinder with its 1” connections. The POWERCYL is an ideal choice for small hotels / guesthouses with multiple showers / baths. A PRV valve 1 - 5 bar, as well as oversized expansion vessels are supplied as standard. The POWERCYL is is a perfect partner to the SUPERSTREAM system where mains flow rates is insufficient. The DELTA series It is elegant and functional in its design, delivering class-leading insulation characteristics and is compatible will all boilers, using smooth piped, scale-resistant heating coil. The DC units can be controlled either via its own thermostat or using a thermistor probe. DELTA uses a high performance fully flooded design, with separate expansion vessel, and an ultra-grade INCOTEC immersion heater as back-up above the heating coil, providing maximum operational safety. A complete set of inlet control valves comes standard. DELTA COIL is also supplied with a digital thermostat compatible with both S & Y plan systems which displays the water temperature and offers holiday and anti-legionella modes.

Advantages: 

MORE HOT WATER
Substantially higher temperature (70°C+), highly efficient mixing valve (no scolding), minimal heat loss and optimal design features gives up to 20 % more hot water and class leading capacity.

PRO INSULATION
The use of NANOPUR™ with insulation values far surpassing Pentane, often in combination with VACUUM panels, ensures minimum heat loss and class leading energy efficiency.

STRONGER
EVERLAST™ titanium alloyed stainless steel in combination with OSO’s unique ULTRAWELD™ system and state-of-the-art passivation process equals class leading corrosion resistance.

LIGHTER
EVERLAST™ titanium alloyed, high tensile strength, stainless steel equals lower weight and efficient use of resources. OSO products are more than 40 % lighter than enameled products.

BUILT TO LAST
INCOTEC™ el. immersion heaters with ultra high-grade Incoloy 825 stainless, DZR brass, zinc-free soldering and carefully calculated surface loads results in maximum durability in hard water.
