Hydraulic balancing and air and (magnetic) dirt separation are combined in the Spirotech SpiroCross AX-J range. The hydraulic separator (low loss header) compensates for differences in flowrate between a primary circuit (supply) and a secondary circuit (demand). Combining three functions in one device not only saves on purchasing costs, but also on space, performance, installation, and total system maintenance costs.The SpiroCross AX-J range has been developed for small commercial applications and can also be used for low temperature heat pump systems. Examples include apartment buildings, shared house systems, villas, and small commercial buildings. Applications include the connection of combined heaters (supply) with different consumption circuits (radiator & underfloor heating) that are both designed as an active circuit in a system with multiple and separate circulating pumps.
