The highest level of comfort

NEXUS M EVI heat pumps enable optimal room temperature with minimal energy consumption. They allow for achieving the right air temperature while also providing access to hot water to fully meet consumer needs.

Advantages of monoblock design

The pump is designed entirely for outdoor installation. Characteristic of the pump is the fact that the entire cooling system is housed in a single unit and only the pipes that supply the building with heat are routed outside.

Operation under extreme conditions

NEXUS heat pumps are innovative system solutions from SUNEX that keep your home warm even at extremely low temperatures down to -25 degrees Celsius. In operation, they offer exceptional efficiency, reliability, and cost-effectiveness.

Pump group GPO HYDRA DN 25

Two-way pump group with Hydra GPO 25-6-130 without mixing valve ball valve DN 25

The two-way pump group with ball valve serves to force the circulation of the working medium in the central heating, process heat, and cooling system. It is equipped with two ball valves with thermometer, a circulation pump Hydra GPO 25-6-130, thermal insulation, and a ball valve with rotary knob.

The GPO 25-6-130 pump can be operated at a constant pump speed, which can be set on the control knob. In addition, it is also possible to control the pump speed depending on the characteristic curve Δp-V.
