Caleffi 549596A Hydraulic Separator Sweat Connection - 1

The Caleffi 549596A is a hydraulic separator designed for use in hydronic heating and cooling systems with a 1-inch sweat (solder) connection. Hydraulic separators — sometimes called hydrodynamic separators or low-loss headers — decouple the primary (boiler/chiller) circuit from the secondary (distribution) circuit, ensuring stable flow rates and optimal system performance.

The Caleffi 549596A features Caleffi's proven internal chamber geometry, which simultaneously performs four critical system functions in a single compact unit:

• Hydraulic separation — eliminates interference between primary and secondary pump circuits
• Air elimination — removes entrained air and micro-bubbles from the system water
• Dirt separation — captures suspended particulates and magnetic debris to protect system components
• Magnetic particle separation — uses an integrated magnet to collect ferrous debris

Constructed from high-quality brass with a compact, vertical installation design, this separator includes connection ports for air venting and sludge purging. The 1" sweat (SWT) end connections allow for clean, leak-free soldered installation in copper piping systems.

Key Specifications:

• Connection Type: 1" Sweat (Solder)
• Function: 4-in-1 — Hydraulic separation, air elimination, dirt separation, magnetic separation
• Body Material: Brass
• Application: Hydronic heating and cooling systems
• Brand: Caleffi (Italy)

The Caleffi 549596A is an ideal solution for multi-zone hydronic systems, condensing boiler installations, and any application requiring hydraulic decoupling between primary and secondary loops.
