OSO DELTA COIL
DC

Ideal for boilers or inverter heat pumps

DELTA series is elegant and functional in its design, delivering class-leading insulation characteristics and ErP* A-rating with heat loss reduced by > 60 % compared to EPS insulation. DELTA has been developed with high grade material selection and intelligent technical solutions exclusive to OSO, and everything we’ve learned over the past 50 years of manufacturing stainless steel water heaters is embodied in the DELTA series. * Energy-related Products Directive – 2009 / 125 / EC. 

DELTA COIL— DC is custom-made for either high- or low temperature energy sources up to 25 kW (boiler) or 10 kW (inverter heat pump), with the smooth piped, scale-resistant heating coil. DELTA COIL has as an ultra-grade INCOTEC immersion heater as booster (or back-up) above the heating coil, raising the DHW temperature to increase capacity and prevent bacterial growth. The booster heater also provides maximum safety if there are any operational problems with the energy source. Sensor pockets for controlling the unit as well as thermometer comes standard. UX mixing valve can be installed for adjustable hot water draw-off temperature (prevents scalding) to the taps.

WHY CHOOSE DELTA COIL?
• Reduce heat loss by 400 kWh* / year with NANOPUR and VIP*
•  Hot water from alternative energy source with el. back-up
•  5 year warranty on the stainless steel pressure tank
* Compared to 200 L cylinder with EPS insulation

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.
