MAXI ACCU – MA HEAT
Accumulator tank for heat
MAXI ACCU HEAT – MA – is the ideal accumulator tank for storage of hot water from heat pump / solar collectors, ensuring optimal working conditions for the energy source and providing stable temperature to the system. MAXI ACCU features dual sets of flow/return connections (400L = G2″F / 600L = DN80 / 1 000L = DN 100), which provide flexible connection and installation options, in addition to a separate G3/4″F connection for air vents, G1″M drain connection as well as G1/2″F sensor connection.
The commercial cylinders in the MAXI series have shown class-leading operational durability
for commercial hot water systems through the last 50 years.
WHY MAXI ACCU HEAT?
- Superior energy-efficiency
- Accumulator provides a stable hot water temperature for the system
- 6 bar design pressure
- Deliverable up to 10 000 liters on demand

Advantages
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.
