Not only is the MAXI range extremely efficient, with industry-leading performance it can also be modified according to customer requirements.
The 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 a large surface area; smooth-piped and scaleesistant heating coil. The units are also suitable for solar collectors up to 40 m². MAXI GEOCOIL has ultra-grade INCOTEC immersion heaters acting as a booster above the heating coil. This feature raises the temperature to increase capacity and prevent bacterial growth. The booster heaters also provide maximum safety if there are any operational problems with the energy source.
