OSO DELTA TWINCOIL DTC
Ultimate solar energy efficiency
DELTA TWINCOIL series is the most efficient solar thermal cylinder available, uitilising unique Vacuum Panel Insulation enabling ErP* B-rated cylinders available from 200 - 300 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 TWINCOIL— DTC is ideal for domestic hot water production from solar collectors up to 12 m² in combination with boilers, with the smooth piped, scale-resistant heating coil.
DELTA TWINCOIL is the most efficient solar cylinder available and can provide up to 60 % of annual DHW requirements from solar collectors. DELTA uses a high performance fully flooded design, with separate expansion vessel, and an ultra-grade INCOTEC immersion heater as booster (or back-up) between the heating coils. A complete set of inlet control valves comes standard. The DTC units can be controlled either via its own digital thermostat or using thermistor probe(s). DELTA TWINCOIL is compatible with both S & Y plan systems, displays the water temperature and offers holiday and anti-legionella modes.

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.
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.
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.
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.
