MAXI ACCU

Accumulator in stainless steel for hot or cold water

MAXI series has shown class-leading operational durability for commercial hot water systems through the last 50 years. MAXI has been constructed with EVERLAST™ high-alloy stainless steel in combination with ULTRAWELD™ technology for optimal corrosion resistance. MAXI series can be modified according to customer requirements. 

MAXI ACCU – MA is an ideal accumulator tank for heat pump / solar collectors, ensuring optimal working conditions for the energy source and providing stable temperature to the system. MAXI ACCU is also suitable as accumulator for cooling systems with ARMAFLEX insulation (add-on). The insulation and the steel outer casing is diffusion proof to prevent condensation against the cold internal tank surface. MAXI ACCU with ARMAFLEX is suitable for room climate systems with refrigerating machines where the unit is the required buffer against the system.

WHY CHOOSE MAXI ACCU?
• Accumulator for hot / cold water provides stable temperature for system

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.
