OSO DELTA TWINCOIL
DTC

Ultimate energy flexibiliy for hot water

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 TWINCOIL — DTC is extremely flexible and can utilize two different energy sources for maximum efficiency in domestic hot water production. DELTA TWINCOIL is ideal for low temperature energy source in lower coil (solar collectors up to 12 m² / inverter heat pump up to 10 kW), in combination with high temperature energy source in upper coil (boiler up to 25 kW.) This way, DELTA TWINCOIL always utilizes the most energy efficient heat source. Alternatively, the lower coil can circulate district heating while the upper coil can provide heating to the household. DELTA GEOCOIL has as an ultra-grade INCOTEC immersion heater as booster (or back-up) in between the heating coils, raising the DHW temperature to increase capacity if required. 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 TWINCOIL?
•  Reduce heat loss by 400 kWh* / year with NANOPUR and VIP*
• Hot water from alternative energy sources for ultimate flexibility
• 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.
