DELTA COIL – DC – is suitable for hot water production from high temperature energy sources such as. solar collectors, district heating, gas or bio-boiler up to 25 kW, or alternatively for inverter-controlled heat pump up to 5 kW. DELTA COIL has an electric heating element placed above the stainless steel heat exchanger for use as additional heat for increased hot water capacity or for summer operation / backup. Mixing valve can easily be retrofitted as an option if required.
DELTA is our most energy-efficient boiler series, and minimizes heat loss with increased insulation, the use of 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, solar collectors or bio boilers. DELTA also has unique corrosion protection and can withstand 3 × higher salt content than other boilers.
WHY CHOOSE DELTA COIL?
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.
