Function

The Caleffi SEP4™ 4-in-1 combination separator incorporates four

important functions for hydronic systems: hydraulic separation, air

separation, dirt separation and ferrous impurity separation.

The unique geometry and design of the separator causes the connected

primary and secondary circuits to be hydraulically de-coupled to prevent

pump conﬂict from occurring. An internal screen element facilitates the

coalescing and capture of micro-bubbles to facilitate high performance

automatic removal, while concurrently causing the capture of non-ferrous

debris particles down to 5 micron size. A powerful magnetic ﬁeld induced

by rare-earth neodymium magnets facilitates the capture of ferrous

impurities such as iron oxide down to microscopic size thus delivering

2½ times the ferrous impurity removal performance of standard air and

dirt separators.

The SEP4™ saves on system installation and maintenance costs as four

devices are combined into one. Additionally, all captured debris is blown

down through the purge valve without requiring to take the system ofﬂine.

Operating principle Hydraulic separation When a single system contains a primary production circuit, with its own pump, and a secondary user circuit, with one or more distribution pumps, operating conditions may arise in the system whereby the pumps interact, creating abnormal variations in circuit flow rates and pressures.
PAGE 4
-in-1 high performance functionality Microbubble air separation The SEP4’s internal air separation element (1) creates the whirling movement required to facilitate the release of microbubbles and their adhesion to the internal element surfaces. The bubbles, fusing with each other, increase in size until the hydrostatic thrust overcomes the adhesion force to the mesh. They rise towards the top of the unit from which they are released through a float-operated automatic air vent.
PAGE 5
Construction details Union connection models 5 The automatic air vent (A), located at the top of the units, has a long chamber for the movement of the float. This feature prevents any debris present in the water from reaching the sealing seat. A stainless steel float guide pin prevents the float from sticking due to accumulating residue in the flowing fluids, even when the SEP4™ is not installed perfectly vertical. A 59829 A replacement air vent assembly is code 59829.
PAGE 6
Insulation The SEP4™ comes standard with a preformed insulation shell for 1" to 2" union connections and 2" to 4" flanged connections. The insulation is made of a shell in closed-cell expanded PE-X foam. This insulation ensures not only perfect heat insulation but also the tightness required to prevent atmospheric water vapors from entering the unit.
PAGE 7
Maintenance Union connection models Dirt separation element To perform maintenance simply use a 26 mm hexagon wrench to unscrew the dirt collection chamber, to which the inner dirt separation element mesh element is connected, for removal and for cleaning. Air separation element The automatic air release valve, located on the top of the unit, has a long chamber for the movement of the float. This feature prevents any debris present in the water from reaching the sealing seat.
