MAXI GEOCOIL – MGC

Water heater custom designed for heat pumps up to 40 kW

Water heater 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.

Water heater MAXI GEOCOIL — MGC has been custom-made for maximum hot water production from heat pumps up to 40 kW (400 L = 25 kW / 600 / 1 000 L = 40 kW), with the large surface area, smooth piped, scale-resistant heating coil. The units are also suitable for solar collectors up to 40m². MAXI GEOCOIL has ultra-grade INCOTEC immersion heaters as booster located above the heating coil, raising the temperature to increase capacity and prevent bacterial growth. The booster heaters also provides maximum safety if there are any operational problems with the energy source.

The electric immersion heaters have optional effect 2.5–15 kW, 230–400 V + N 3-phase, and is thermostat controlled 50–75 °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 water heater MAXI series, with double sealing for an added layer of safety.

WHY CHOOSE MAXI GEOCOIL?

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.
