Caleffi Hydro separator

Hydraulically separate Primary and Secondary heating system circuits easily with improved performance and reliability.

Description

The Caleffi 548 and NA548 series hydraulic separator creates a zone with a low pressure loss, which enables connected primary and secondary circuits to be hydraulically independent of each other; the flow in one circuit does not create or interupt flow in another. Hydraulically decoupling primary and secondary circuits eliminates pump conflict. This device includes an automatic high-capacity air vent with service valve to discharge accumulated air within the circuits.
