Accumulator tank from the MAXI series has for 50 years shown outstanding operational reliability for larger water heater installations. MAXI accumulator tank is constructed with EVERLAST high-alloy stainless steel in combination with ULTRAWELD technology, and has market-leading insulation properties that provide large energy efficiency gains. MAXI is available in 300–1000 L with 10 bar pressure class and can be customer-specified if required.
The accumulator tank MAXI ACCU GEOCOIL – MAGC is specially designed as a heat accumulator tank for heat pumps or solar collectors, with preheating of domestic hot water by using the high-efficiency pipe coil. Suitable for most of the larger heat pump solutions. MAXI ACCU GEOCOIL can also be connected to a heat pump with domestic hot water prioritisation up to 30 kW, or to solar collectors with a heat exchanger in between. With preheating of the tap water, the accumulator MAXI ACCU GEOCOIL ensures improved operating conditions for the heat pump (higher COP), higher tap water capacity and stable temperature of the system. The pipe coil preheats the cold water and lowers the return temperature of the heat pump or solar collectors significantly, thereby increasing the efficiency (COP).
WHY CHOOSE MAXI ACCU GEOCOIL?
• Accumulator tank for heat pump or solar collectors
• Large preheating capacity of domestic hot water provides better COP
• 10 bar pressure class and market-leading corrosion resistance

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.
