DELTA GEOCOIL – DGC – is specially designed for maximum efficient hot water production against all types of heat pumps up to 18kW (200 L = 15kW / 300 L = 18kW), thanks to the large heating surface (2.6 – 3.1 m²) on the heat exchanger. DELTA GEOCOIL comes standard with electric heating element at the bottom of the tank for maximum protection against legionella (must be controlled externally). The element can also be used as a backup for the heat pump when needed, which provides maximum operational reliability. 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 GEOCOIL?
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.
