MAXI COIL - MC

Hot water cylinder with unbeatable performance and energy flexibility

The hot water cylinders from the 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.

The hot water cylinder MAXI COIL — MC is ideal for direct electric operation during summer and can be switched to boiler operation during winter. It provides an attractive alternative to the TURBOSYSTEM when hot water demands are somewhat smaller. MAXI COIL comes standard with a smooth piped, scale-resistant heating coil with a capacity of up to 30 kW from boiler. The electric immersion heaters has optional effect 5–15 kW, 230–400 V + N 3-phase, and is thermostat controlled 60–90 °C in three steps with separate safety thermostats. Contactors are not required and the support cable is connected directly to the central. Installation kits for cold water inlet with shut-off valve, hot water outlet with mixing valve, plate heat exchanger with pumps (TURBOSYSTEM) and piping for connecting multiple units has been custom-made to fit directly on the MAXI series, with double sealing for an added layer of safety.

WHY CHOOSE MAXI COIL?
• Energy flexibility for summer / winter operation, or as back-up
• Extreme operational durability with el. heaters w/o contactors
• 10 bar design pressure and class-leading corrosion resistance

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.
