DELTA TWINCOIL – DTC – is extremely flexible and can utilize several energy sources for maximum efficient hot water production. DELTA TWINCOIL fits most combinations of renewable energy sources (solar ≤ 12m2 / heat pump ≤ 5 kW) in combination with high temperature heat source (gas or bio-fuel boiler up to 25 kW.).The electric heating element can be used as backup heater, additional heating for added capacity, or legionella protection (controlled externally).
DELTA is our most energy-efficient water heater series, and minimizes heat loss with best-in-class
PUR insulation, vacuum panels and functional design. DELTA has been developed with a number
of smart technical solutions especially suitable for alternative energy sources such as heat pumps or
solar collectors. DELTA also features unique corrosion protection technology.
WHY CHOOSE DELTA TWINCOIL?
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.
