The new GEO BASE Pro is a 3-stage heat pump with a built-in advanced control system. GEO BASE is designed for heating large buildings, such as apartment buildings and industrial premises.

Thanks to the use of separate cooling modules, GEO BASE Pro is capable to increase power output in three stages. As a result, the pump operates more smoothly and is better adapted to different requirements for building volumes. The number of starts/stops has decreased and the degree of thermal comfort has increased in comparison with the 1-step analog. In addition, the individual cooling modules also have a very low noise level.

GEO BASE Pro is available in three sizes: 25, 30 and 35 kW, which can be connected in series and generate power of up to 170 kW (5 ground pumps, model GEO BASE 435i Pro). The unique control system Logic Pro is built into GEO BASE Pro and controls, as well as regulates, heat pumps, solar panels, peak heating, buffer tanks, pool, cooling, etc.

To achieve the lowest possible energy consumption and the greatest savings, the GEO BASE Pro is equipped with a class A circulation pump with low power consumption, both on brine and on the heating surface.

Due to the newly developed refrigeration circuit and high-efficiency compressors, GEO BASE Pro can heat water up to 65 degrees Celsius.

This means that you can have more hot water and warmer radiators.
Ideal for premises with high primary flow temperatures.

GEO BASE Pro is designed to be connected to either new heating systems, or to already existing systems. The heat available in a rock, soil or lake water is used as a heat source.

The brine system can be easily connected to the right, left, top or rear.

GEO BASE Pro is a safe and obvious choice.
