NIBE KB 25 Filling Kit

Description

NIBE KB 25 is a complete filling coupler and a functional filling kit adapted for filling brine and brine liquid for ground source heat pumps and geothermal heating systems with an output of up to 12 kW. This filling valve facilitates installation, commissioning and service by ensuring a smooth flow of liquid to the collector hose while protecting the system against contamination.

Robust construction and reliable protection

The unit is equipped with an integrated dirt filter that effectively prevents particles from reaching the circulation pump and heat exchanger. The included molded EPS insulation minimizes energy losses and prevents condensation around the valve housing, which contributes to long-term reliable operation. The valve body is made of durable brass and designed to withstand operating pressures up to 10 bar, making it a safe and durable component in heat pump installations.
